Title: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on November 05, 2015, 01:09:01 AM
A bit of history on this thread first. At this year's Cabin Fever Todd and Joy Snouffer were offering their plans and castings for both the vertical and horizontal versions of the Parsell & Weed hit and miss IC engines. The plans looked very well done so I (and I think Stan also) bought a set with the intention of making it from bar stock rather than castings which I still think can be done. Anyway, about a month or six weeks ago I had an email from Todd indicating that he was making some changes to the drawings (reducing compression and a few other things) and once done would ship out a new set of the drawings to those that had purchased them already. Last Friday, I had another email from Todd saying that the new plans were ready and would ship out this week at no charge....but to those that had purchased them before he would offer a $50.00 discount on the casting sets as well. Well not being one to pass up a bargain...and not wanting Jo to get more than 100 casting sets ahead of me, a few email back and forth between me and Todd and I had a set of the horizontal castings headed towards NC, including the updated plans. Let me add here that Todd is a member of the forum under the name "littlelocos" and also add that the plan set covers both the horizontal and vertical versions of this interesting engine.

The castings arrived today in pristeen condition and very well packed and though I have no affiliation with littlelocos.com this level of customer service and care for details I just had to share. Below are some pictures of the shipment. Picture 1 is of the priority shipping box as it was opened, the plans in the back, casting in the front. Picture 2 is of some of the smaller castings (all bronze), the gear stock, and a couple of pieces of bronze bar stock all neatly packed in a plastic box and cushioned with foam peanuts. Photo 3 is of the two flywheel castings. Photo 4 shows the larger castings, a few more pieces of bar stock and the large base casting. Cletus you will appreciate the fact that the kit includes the CD of construction photos at no additional charge. Photo 5 shows the base casting alone, and the last photo a plastic tube containing a length of small music wire for one of the springs.

More information and pictures of these engines can be seen at www.littlelocos.com

In an age where we are often quick to point out poor customer service, inferior products, and inaccurate drawings...it nice to see a supplier to the hobby doing things RIGHT!!  Many thanks Todd and I am looking forward to starting on this one as soon as I finish the Vickie, if not before. Some of the smaller parts will be ideal for even the Sherline equipment. The Lil Brother casting set, equally inspiring, may be moved behind the Parsell & Weed in the build order as this one really intrigues me and seems to be a straightforward build. I will post updates as appropriate, but am one happy camper to add this set to the casting collection.

Those are some nice looking castings Bill.

This engine is smaller than the original; maybe 1/2 size?

I picked up an original hard bound book on the Parsell & Weed a number of years ago a Powell's book store in Portland OR. Fun to flip through the pages but I was never sure if I would build one or not.

Looking forward to seeing this one under construction on MEM.

They do indeed look nice castiongs, I'll be following along as I know someone with the larger casting set who I have built engines for in the past. I also have a copy of the book which I think can be found online.

Bill, great score it appears. It was nice to have the video "included". I think that's the difference one sees when dealing with a smaller, often times, owner ran business versus a big company. Can't wait for the build to begin. I went to the website and that "Puck" sure looks interesting :thinking: Tell everybody hey.

Thanks for the interest guys. I opened up the plans tonight to peruse them some and check out what has been changed/added. Interestingly enough the serial number of the set I got at Cabin Fever was 1505 (5th set sold in 2015 as I recall), the serial number on the replacement plans is 1505R (revised). Isn't it nice when people pay attention to the small details too.  Really looking forward to getting a start on this one, even if just some bits and bobs from barstock. More to come. The plans come in a comb bound book, just a couple of pictures attached, I don't think Todd will mind that.

It does look very desirable Bill, I think I might have space enough to mature a set of those castings if I just move a few around...   :naughty:

Well not being one to pass up a bargain...and not wanting Jo to get more than 100 casting sets ahead of me,

As you will recall Bill this years resolution was to try not to buy any more casting sets: I have tried and I have only added another 7 to the other 43 sets (excluding duplicates like the Triples  ;)) and I am/have built 5 so far this year,  I will try to do better next year :mischief:

P.S. I don't yet know  :hellno: that father Xmas has another 2 casting sets for me

It is a good buy for those of us this side of the pond as $50 shipping is about a third what I would expect to pay for a similar sized engine. Though as its free in teh US there must be some shipping costs built into the base price. Still a good buy.

Bill will you be doing it like the book - all made on a lathe without even a bench drill :mischief:
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: littlelocos on November 15, 2015, 01:09:46 AM
Thanks Bill and everyone else for the encouragement.  Joy and I are tickled that you like the kit.   :pinkelephant: :cartwheel:

Since the prototype we had at Cabin Fever went to Woody Sins in NY, I'll be building my own engines this year as well.  Hoping to build four between now and Cabin Fever 2017 both horizontal and vertical in both water and air cooled.  These should go a lot faster now that I've built one and won't be taking as many photos along the way.  I'm working on the air cooled patterns now based on a photo I found a few years ago on the Internet.

Thanks again,
Todd.

For those of you interested in the full sized versions you can have a look at mine. There is a  link to mine running on my site here:

http://davesage.ca/parcell%20and%20weed.html (http://davesage.ca/parcell%20and%20weed.html)

I built mine water cooled like the original.

I got the incentive to build it from Steve Kahler after seeing his at NAMES a few years ago.
Here is a link to Steve running his air cooled version.

https://www.youtube.com/watch?v=jgxaWPpy7yM (https://www.youtube.com/watch?v=jgxaWPpy7yM)

Both of our engines were built from the book and have 14" flywheels and weigh in at about 90lbs. They run on propane and have the original air/gas mixer intake valve instead of a carburetor and gasoline. Steve designed the nice pedestals and I copied them.

I also added a mechanical piston water pump and eccentric to one side of mine and hid a small computer radiator and fan underneath rather than have a water reservoir.

Enjoy.

Got a start today on the muffler. Some of the smaller parts are ideal for the Sherline equipment so that seemed like as good a starting place as any. Below are the pictures from today. Unfortunately I didn't take any of turning the angles on both the front and back of the muffler parts, but the Sherline lathe compound was used for that on both the outside of the profiles as well as the inside as shown in picture 4. Rather than riveting the two halves together, instead I threaded the back side for 1-72 and used three 1-72 SHCS's to fix the two halves together, making it easier to disassemble if ever necessary. The rest is pretty straightforward. I am excited about making the first few chips on this one!!

Thanks for looking in Vince, Alan, Roger, and Dave!  I got a bit more done today on some of the smaller parts, lath work mostly. First up was the Governor weight, just a simple cylinder of brass 3/8" dia. x 3/8" long with a .125 bore and a threaded hole for a grub screw/thumb screw for adjusting it. The three pictures below a self explanatory with the obligatory mini-mic pic :).

Bill
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on November 27, 2015, 09:17:46 PM
Next up today was the brass Mixer Body, also made from a short length of brass. This will eventually attach to the cylinder head but uses a 12-40 thread and I have neither the tap or die for that size as it isn't very common so will need to order those from MSC before I can thread the thin end of the Mixer Body (photo 1). Otherwise it is finished though. The big (inlet) end of the mixer is tapered using a 60 degree center drill as shown in photo 2. Photos 3,4 & 5 show drilling the holes for the Jet to attach to the bottom side (5-40 thread), and for the needle valve to attach to the top side (1-72 thread).

Bill
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on November 27, 2015, 09:28:41 PM
Lastly, the Jet was machined from a short piece of 3/16 hex brass, because that is what I had on hand. Photo 1 shows turning the diameters while leaving a shoulder on the end that will be threaded 5-40. Photo 2 shows it after threading the short end and using the compound attachment to turn a taper on the end.  Somewhere in here a 1/16" hole was drilled through the length of the Jet. After parting it off there wasn't much to chuck on to taper the opposite end so I drilled and tapped a 5-40 hole in the remaining length of brass hex (photo 3). Photo 4 shows the Jet threaded into this makeshift adapter and the turning of the taper on that end. Photo 5 shows the finished Jet (kind of small too) and the last photo shows it threaded into the mixer body.

Thanks it for now, thanks for looking.

I'll do what I can Don, still have the Vickie to finish too though and haven't forgotten her. Also making a dollhouse for the granddaughter for Christmas so what shop time there is has to get spread around. These fiddly bits are great for the Sherlines though and there are plenty more fiddly bits to go. This really isn't that large of an engine, though I will still have to do the base and flywheels at work on the larger machines. Thanks so much for the support. I'll try to keep it interesting.

Post by: b.lindsey on November 28, 2015, 06:17:25 PM
Thanks Kim and Achim!  I had a PM from Todd at Littleloco's last night noting that the bore in the mixer jet should have been .047" rather than the .063" I said in my past post. This was my error in looking at the old drawing set rather then the new updated set where the change was shown in the newer drawing. I made a new mixer jet this morning with the correct bore and will be working just from the new drawings from now on.

After that little correction, I began working on the needle valve and the speed adjustment screw, both of which are threaded 1-72. Rather than making them from solid 1/4" dia drill rod, I turned down and knurled a length of 1/4" drill rod to the .219" diameter called for and parted off 5 pieces ( a few extra since the shop gremlins already grabbed one ) after drilling and reaming a 1/8" hole thru for later attachment of the actual screw part. See photos 1 & 2.

With that done, I used 1/8" drill rod for the screw threads. After turning a .094" shoulder, and turning the remaining length to .073" for the 1-72 threads, the threads were cut using the tailstock die holder and the result parted off leaving enough of the 1/8" raw diameter to extend through the knurled heads (photo 3).  The same procedure was used for the needle valve after turning the sharp point on the end using the compound set to a 17 degree included angle (photo 4). The knurled heads were loctited to the 1/8" drill rod and once set, the excess was ground off, sanded flush and polished as shown in photos 5 & 6. The final picture shows the needle valve inserted into the mixer body opposite the jet and the speed adjustment screw.

Professor,  ain't it something what a couple of days off and some good sweet potato casserole will do  8). The parts and pieces are looking great and seem well suited for the Sherline.  On my last two builds I made each part per the drawing,  stockpiled,  and then assembled much like a mechanic's kit.  If there are no drawing errors to contend with, I think it makes you work harder at getting that "perfect part.  Tell everybody hey and I'm a watching from down at the diner  :popcorn: :DrinkPint:.

Post by: b.lindsey on November 29, 2015, 09:31:54 PM
Cletus, you about to recover from the holiday cooking yet?? Thanks for looking in.  Between yesterday and today I got a couple more parts finished up...the governor support and the governor rocker, both little brass pieces.

The support is pretty simple so I didn't really take any pictures of that other than photo 1.

The rocker is a bit more tedious and requires several different set-ups. I first milled a piece of .250"x .500" brass to length (photo 2), then located and drill the 3 required holes (photo 3). Then I began milling away the excess areas as shown in photos 4 & 5, resulting in the rough shaped piece shown in photo 6. With that done the 22 degree slope needed to be milled down the centerline and this required using the angle plate along with the Sherline vise as shown in photos 7 & 8. With suitably sized pins as a pivot, I milled the radii on both ends (sorry no photo of that) and then also milled out the relief in the larger end the same width as the sloped section.

Bill
Title: Re: Parsell & Weed Horizontal IC Engine

Post by: Don1966 on November 29, 2015, 09:44:56 PM
Boy those are some small fiddley bits Bill. Is the vise on your angle plate a swivel vise? I bought a sherline vise for mine last month and I will kick myself if that's a swivel vise.

Don
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on November 29, 2015, 09:53:52 PM
Don, yes the vise is mounted on a swivel base. You should be able to buy it separately from Sherline. I'll take a couple of pics for you, the vise just slides into it and is held down by four screws.

Bill
Title: Re: Parsell & Weed Horizontal IC Engin
Post by: Don1966 on November 29, 2015, 10:08:44 PM
Thanks Bill I thought the vise was a swivel vise as well. But it's like mine then just bolts to a swivel plate.

Don
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on November 29, 2015, 10:12:10 PM
Don, here you go...the vise is just a close slide fit into the base and you can see the 4 screws with washers that mate with the hold down groove in the vise itself. The other two screws are for loosening and tightening the swivel feature. Hope that helps. This is the vise  and base that came with my equipment about 18 years ago. It has held up well but I do wish they would make a similar vise out of steel. You can also see the witness mark for setting the angle. Keep in mind though that the spacing of the hold down screws on the four corners of the swivel base are spaced to fit the Sherline tee slots, so using in on another mill table would require some adaptations.

Bill
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: Don1966 on November 29, 2015, 11:03:51 PM

Professor,  thanks for asking, but to be honest,  not really.  From Monday thru Saturday I'd been there almost 68 hours  and we were closed Thursday.  Christmas parties start Friday  :facepalm:.

I may try to take the base to work this week and get it done, mostly layout and drilling some holes, but we'll see. Only three more classes till the end of the semester so things will be hoppin'.

Nothing to report yet but should make some more progress over the weekend. This week I got the 12-40 tap and die and a few pieces of metal from online metals when they were offering a 30% off sale on any size order. The shipping is still pricey I think but the 30% off the metal order made it a bit easier to swallow at least. Some brass tubing for the gas tank/cooling water tower, a piece of 3/8" brass square for one or two parts, some 1018 mild steel for the main side rods, and some 1/4" drill rod used for various small parts. Will post more as I make some chips.

Post by: b.lindsey on December 07, 2015, 12:30:48 AM
Aside from dyeing some dollhouse shingles today and making my hands a nice shade of reddish brown, I did get a few small things done on the P&W. As I had noted, the 12-40 die arrived this weeks so I finished up the mixer body by threading the end of that (photo 1). The now completed mixer is shown in photo 2.  Next was turning up the governor roller from a piece of .250" drill rod (photo 3) and a couple of 1/16" pins (photo 4). The roller (made from W-1 drill rod) needed to be hardened so that was done (photo 5) and then cleaned up and fitted to the governor rocker (photo 6). With those little bits made, I turned to working on the two side rods. The last photo shows the first couple of steps completed on one of them. The opposite end will be turned down smaller and the end threaded to 8-32 (as soon as I find my 8-32 die). I know I have one somewhere  ::)

Hi Bill

Will you be able to do any work on the castings on your Sherline equipment? Also I was wondering if you do single point threading on your Sherline Lathe; and if their system works pretty well?

Dave
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on December 07, 2015, 01:21:08 AM
Dave, yes, many of the castings can be machined on the Sherline machines also. Just haven't gotten to them yet. The main support casting will however require a full size machine or at least that is the best option for doing it. I do have the thread cutting attachment for the Sherline lathe but in all honesty, I have not tried it yet. I find it much easier and more consistent to use dies in a tailstock die holder though not under power. The die holder and live center just keep things centered as the thread cutting is done manually. I had purchased that attachment for some very abnormal threads that will be required for the Wright 1903 engine, though that one has been on hold for a long time now. Eventually I will get back to it though and that is when the thread cutting attachment will begin earning its keep.

Nice work, Bill!  I agree, you do take great photos!

That was one of my problems with my Taig lathe - no way to do threads.  There were several examples on the internet of way's people had worked around it, but I chose to work around it by asking for a new lathe for Christmas a couple of years ago :)  I've Never regretted that!  Still use the Taig lathe from time to time, though its currently lost it's bench space to the tool grinder I recently made.  I just need a bigger shop!

I'd love to hear how the Sherline thread cutting works when you get around to it, Bill. I'll expect a thorough report! :)

Sorry to interrupt ... A message for Dave Otto ... I also have the thread cutting accessory for the Sherline and have used it a few times. Set up is fairly easy and results are excellent. I have threaded brass, aluminum and 12L14 steel.

Now back to an excellent build thread.

Nice work Bill!

Regarding smaller equipment (Sherline et al) we had thought about following Parsell & Weed's approach in offering machined flywheels for those folks who's equipment wouldn't swing the 5" flywheels.  Not sure if there would be interest in that.  (The original flywheels were 14" and most home shops didn't have a lathe that large in 1902.)

The horizontal base should be do-able on tabletop equipment, but would definitely take a while to machine the bottom surface.  The vertical is essentially half of the horizontal, just a little wider.

Any thoughts?
Todd.

Todd, your could certainly run the idea up the flagpole and see if anyone salutes it as they say. I do have access to full size machines so it isn't an issue for me. You could well find some other tabletop machinists though who might like the idea of the base and flywheels already machined, leaving the rest to be done on smaller equipment. You could be asking for a lot of extra work though if it were to take off and it could also depend on the upcharge for buying these castings pre-machined. By the way, thanks for the mailing today, will respond to that separately via email tonight. I hope others will chime in here as to your idea though, such discussion can be helpful to all of us.

It's tough going on drill rod though. I only went far enough on some 3/8" rod so that I could get a die on straight.

In regards to sizes, the biggest problem I think is that most model ads don't really give a good indication of the size of equipment needed to make them. Flywheels are obvious but a lot of ads don't even give flywheel sizes.
Its often easier and safer to start with a dimensioned drawing and try to scale it to fit the machining envelope.

I look at the PM castings and mostly wonder if there is a reasonable way to do them on the Sherline machines that I have. If they were just a bit oversized it might be nice to get the bigger parts premachined.

Post by: wagnmkr on December 09, 2015, 12:58:24 PM
I agree with Alan ... Quite a few adverts don't give the info required to decide if the kit can be done on the machinery on hand.

I would also agree that being able to get a machined flywheel and possibly a base would be helpful. I am working on a Stuart beam at the moment and it came with a machined base due to most hobbyists of the time not having larger machines. It was a great help in getting started on the engine.

On threading drill rod, like Alan,  I had never been able to get a clean thread by single pointing. The crests were like a saw blade.
Out of curiosity, on an order from McMaster, I added a few sizes of "Ultra Machinable Drill Rod."
Not perfect, but a major improvement on the threads. I'm guessing it's some variant of 12L14 or at least has lead in the alloy.

This morning I finished up the first of the two side rods with the exception of threading the small end 8-32. Can't seem to locate that die at the moment...hoping it may be at work. This is shown in photo 1. The second side rod will follow along shortly.

Then I went to work on the crank journal that connects the two flywheels. This is a turning operation. After parting off a short length of .313" drill rod (Photo 2) and facing each end to the final length I drill a #19 hole through (photo 3). Both ends were then turned down to .250" as shown in photos 4 & 5). This is a push fit into the flywheels so I machined to dead on .250". Once this was done, I chucked on one end of the journal and used a live center in the other to take light cuts with a grooving tool (sorry forgot to take a picture of that) until the actual journal was close to the .250" called for leaving the shoulders a bit wide in the process. Then a left hand and a right hand facing tool was used to square the shoulders and bring them down to the .063" width called for leaving the journal with a width of .313". At this point I polished the journal. The actual spec for the journal diameter is .250" +.0000/-.0015. I polished it down to .0002" under for a final diameter of .2498" (photo 6). The finished journal is shown in the last two photos. The ends that will fit into the flywheels were left as machined at the .250" diameter.

That is looking great! I have the new plan set from Todd and, like Chuck, thinking about doing it from barstock. It should be doable between the Bridgeport and the big lathe. I will, however, look at the casting set at CF and discuss this with Todd at the Little Locos booth.
Keep it up. Work is certainly a distraction.

Post by: b.lindsey on December 31, 2015, 08:51:00 PM
Well nothing like ending 2015 with a mistake. I was machining away on one of the Cylinder Collar castings and was about done with it when I apparently miscalculated when cleaning up the final OD of the casting. Anyway I will show the pictures of the machining up to that point and shoot a PM off to Todd to see if I can get another casting.

Photo 1 shows the casting mounted in the 4 jaw chuck where the various diameter bores were made to the proper depths. After removing the 4 jaw (photo 2), I flipped the part around to face off the back side to the specified width (Photo 3). Then the 3 jaw was mounted to the rotary table, to locate the two larger holes though not drilling the one through the squared off tang yet (photo 4). To maintain alignment and squareness the rotary table was mounted vertically to tap drill the two #50 holes in the square tang of the collar (photo 5). With this done the larger two holes were drilled and then the width of the square tang machined to its correct width. Feeling pretty good so far about how things were going, I recentered the part on the rotary table (back in its horizontal position) to machine the major OD of the part down to the 1.38" called for. All I can figure it that I miscounted the handwheel turns and machined an extra .050" per side off the diameter because it ended up at 1.28" rather than 1.38. A few choice words ensued. You can see in the  final picture where the major OD should be equal where it runs across the square and rounded tangs, and it obviously isn't. Drats !!!  In hindsight I should have flipped the part over again before this step to provide a visual indication of when I was getting close. There are a few things I will do different on try #2. The other collar is substantially the same so I can work on it while seeing about the replacement casting.

Guess its better to end the year with a mistake rather than starting the new year off with one, but still  :slap:

Happy New Year Everyone!!

Hello Bill,
Tough break on the cylinder collar.  Sent you a PM regarding a replacement for you.  Don't feel bad.  I went through 3 of the original CI castings when machining the prototype -- one of which I snapped when locating it on a centering fixture.

Also, I just got a call from a builder in Iowa.  He found a discrepancy between the collars PW-6 & 7 and the pushrod guides PW-29 & 30.  He straightened his out, but I still need to revise the drawing for the guides so everything lines up.  I'll be fixing the error on Sheet E19.

I've also notice a few labeling issues on the exploded view and will be taking care of that as well.

Happy New Year,
Todd.
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on December 31, 2015, 11:34:51 PM
Thanks for the heads up Todd, I'll take a look at the drawings. Looking at Sheet E19, it looks like the hole spacing is off as far as mating with the holes in the collar ...is that the issue? In any case I am not working on PW29 & 30 yet so not an issue for me yet. I am assuming the dimensions for both collars remain the same though.

Bill
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: littlelocos on January 01, 2016, 12:40:37 AM
I checked the 3D model.  All is well there.  There was a dimensional scaling issue with the detail for PW-29.  The 0.100 dimensions from the edges of the parts should be 0.075.  (Dim Scale was 0.6667 for those two instead of 0.50 to match other dims.)

See attached rendering and revised drawing sheets.
Enjoy,
Todd.

Thanks Kim and Happy New Year to you!!  The castings machine fine, it was my head that slipped a gear :). Already got it sorted out with Todd from Littlelocos, replacement will be on the way, we have communicated several times this evening on this and another matter he noted above as well.

Just so everyone knows, Todd offered and to add some photos along the way of things that he did while prototyping both the horizontal and vertical versions of the engine.  So if you see some additional photos from him, I took him up on his offer to tag team in the thread. More info can't hurt and may help future builders as well.

Yes I did stop for tonight at least. Watched the Clemson vs. Oklahoma game and now the Alabama vs. Michigan St. game is on. Dogs laying next to me on the couch...life is good !

No shop time today as I drove up to Raleigh to visit my younger daughter, son in law and grandson. Finally the rain subsided for a day or so, so it was a cool but beautiful day. The grandson (now 4) loves the airport (or "airpork" as he calls it), so we visited the Raleigh/Durham airport for an hour or so among other things.

Anyway, yesterday I spent so shop time working on the cylinder and have attached a few pictures of that, Still need more lapping of the bore and a hole drilled and tapped for the oiler, but so far so good. The last couple of pictures show it fitted up to the now defunct collar, which I am still using to check fits. Tomorrow I hope to finish up lapping the bore and machine the brass water jacket which will fit between the two collars and over the part of the cylinder that isn't polished in the pictures.

Though the winter break is now over for faculty, the students don't return until next Monday so its has been a rather quiet week before the coming mayhem!!  While I had  a chance  today I went down to the machine shop and got a start on the base casting. I got the stands milled off to the proper height (photo 1) and then turned the casting over to clean up the bottom side. There were four gates protruding down from the underside of the base so I milled those off first (photo 2) and then took a series of cuts to bring the overall height to size (photo 3). It cleaned up nicely though I need to do a bit of file clean up along the edges. I hope to get the 8 holes (two on the top of each stand) located and drilled tomorrow morning with the help of the DRO's on the mills at work. Once that is done I will also drill the four mounting holes through the feet. That will be about it for the base, but will give me something to start hanging things on as they are completed :)

OK Bill I have to ask:  I have been wondering what others are thinking when it comes to the brass and bronze on these little engines.  Paint it, or polish it?  :-)  If left unfinished, it will likely take on a nice patina.

I'm torn as to how to finish my engines, so I will likely opt for both.

Post by: b.lindsey on January 06, 2016, 02:29:25 AM
Todd as to the base, I will leave it as cast except for the machined surfaces meaning I won't machine the other non finished surfaces. My thought for now is to paint the base and flywheel spokes and polish the flywheel rims and the other bronze / brass parts. Not sure yet about the side rod support castings, will see how it looks down the road in that regard.

If I were doing one I would be painting anything that would have been iron on the original including the flywheel rims as the engine has a pully they would not have been left bright. Just some of teh small bras items and moving steel ones would likely be left bright and then only to 150grit abrasive not polished. But thats just my way, others will have their own way.

Using the steel surface plate and some 220 grit paper I removed the burrs raised by tapping the holes in the pillars and got rid of the Dykem as well (Photo 1). Just to make it look a bit better (even though it won't be seen) I did the same to the underside of the base casting to get rid of most of the machining marks (photo 2).

Then it was on to the water jacket and finishing up the last detail on the cylinder. After squaring up one end of the brass tubing supplied for the water jacket, I parted it off just over the required length and then faced the parted off end to the final length (photo 1). The inlet and outlet tubes of the water jacket are 180 degrees apart so to insure that was the case I used one of the lathe chuck arbors in the mill vise to drill the first hole (photo 2) and then rotating the arbor 180 degrees to locate and drill the second hole on the opposite end (photo 3). After tapping both holes 3/16"-40 and a little clean up and polishing, the water jacket is complete as shown in photo 4.

I still needed to drill and tap a 5-40 hole in the back end of the cylinder for the oiler shown in photo 5. After deburring the inside of that the bore is now looking good and smooth (photo 6), and the last picture shows how the water jacket will fit over the cylinder (not sure if I have it oriented right or not but you get the idea). Both the ribs on the cylinder as well as the ends of the water jacket will be sandwiched between the two collars. I will likely get bock to work on those this evening and tomorrow.

Thanks guys, yes Don I spent a lot of time on the cylinder until I was happy with it...boring first, flexhone, then lapping with some clover compound I had on hand...rinse...repeat (not the boring of course).

Vince, I know what you mean...it is satisfying and I often have the plans handy to look at or think about the next part too. If that doesn't do it, I can always work with the brown stuff too. Actually I stopped by the big box store this week to get the oak for the skid it will be mounted to. I am modifying Todd's plans a bit so that it will look more like the one I did for the Briggs engine.

I was missing the brown stuff a bit and had already gotten the necessary red oak project boards I needed for the base. Yesterday at work I laid out the side rails and sliced through the areas to be removed with the small table saw there (sorry no pic of that).  This morning I clamped the two side rails together and using the mill cleaned up the slots depths and widths to the required dimensions shown in the plans (photo 1). I should note that I am modifying the base to a design more similar to the one I used for the Briggs engine. I wanted there to be a radiused underside on the ends of each runner (forming handles in a way) so I used the band saw to rough those out and then back to the mill to mill closer to the layout lines (photo 2) and then finished the contour with a sanding drum (photo 3). It dawned on me that once everything was glued together I wouldn't  be able to chamfer the inside bottom edges of side rails so I did that before gluing anything together. I will have a picture of that in the next post. The last three photos included here are just of a rough fitting up of the side rails and cross pieces with the engine base shown in its approximate position. More to follow later this evening.

Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on January 16, 2016, 10:34:40 PM
Thanks Don. I had mentioned chamfering the edges in the above post. The first picture below shows the results of doing that to the lower edges only of both side rails. I have a small Bosch router I got years ago mainly intended for use to chamfer formica laminates on countertops. I have always just used it to break the edges of all my bases. The second photo shows the base after gluing up the second side. Those little hand squeeze clamps available in various sizes come in real handy for things like this. Once the glue sets up I will use the belt sander to make all the joints flush on the sides and top and then use the router again to chamfer the top edges and the inside edges of the rails and cross pieces. Then it will be ready for staining and finishing. Meanwhile I haven't forgotten about the metal parts...I've been working on a few of the smaller fiddly bits as well and will post those later or tomorrow.

I like that bit of joinery, Bill.  Oak can be a bit touchy, but I like working with it anyway.

Are you going to stain it, or just go for a clear coat?

Joe
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on January 17, 2016, 03:39:50 AM
Thanks Joe. It will be stained then finished with polyurethane. I use red oak for all my bases and minwax golden pecan stain so that the color remains consistent from base to base aside from the natural variations in the wood. Boring perhaps but works for me.

Bill
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: Don1966 on January 17, 2016, 03:48:00 AM
Bill if you have any gaps in your joints just put some glue in it and sand over it. This will fill it with saw dust and make a perfect joint. Learn that one from old Norm on this old house.

Don
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: sshire on January 17, 2016, 04:13:04 AM
I was always a big Norm fan, but...
Filling gaps with just glue and sawdust will prevent stain penetration. The part that Norm missed was to stain first, then mix the glue and sawdust with stain to match the color.
The real cabinetmakers mix the sawdust with a mix of stain and shellac, not glue.

Post by: b.lindsey on January 18, 2016, 04:15:04 PM
Here are the rest of the pictures of finishing up the base. The first two are after the belt sanding to get all the joints flush both with the side of the rails and along the top of the rails as well. Next I used the "mouse" palm sander to go over all the main surfaces again. This oak really cleans up nice and smooth...I like working with it. With that done I went back to the router to chamfer the inside of the top rails and the boxed in areas formed by the cross pieces as shown in photos 3 & 4. Photo 5 shows the whole base up to this point and the last photo is after one coat of the stain. Back to some metal work today...

Thanks Joe and Kim. Now back to metal dust. The flywheel shaft running side and flywheel shaft off side are more polishing tasks beginning with 1/4" drill rod. The running side shaft does require turning for a short distance down to .188" +.0000/-.0005, and for now I left it at dead on .188" (photo 1). On both shafts there is the journal region which is specified as .250" -.0010/-.0015 and a fit into the flywheel region specified as .250" +.0000/-.0005. So lots of polishing here with the fine Micro-mesh sticks to get to the specified tolerances but both are done (photo 2). The through holes in the running side shaft will wait till later as I may use small taper pins rather then straight .047" pins. That's it for the moment.

Many thanks guys, that's it for the brown stuff fir this build though. Got a couple of more little bits done this afternoon, first was the piece that goes through the flywheel journal that joins the two flywheels. Just a simple turning and threading job as shown in the first three photos. Then I knocked out one of the pushrods except for a notch at the non threaded end that has to be located at assembly. Nothing much there, it looks bigger than it is...its 1/8" drill rod and 2.69" long so rather small. Getting down into the teens tonight and the garage is getting cold so that's it for the moment.

The base is a beauty. Perfect complement.
Since Todd was right across the aisle, I kept waffling on taking the castings home. Changed my mind about 6 times. I've decided to wait as I have to finish the Coventry and have just received the metal for a "big" build.
Anxious to see yours completed (as I'm sure you are.)

Thanks for looking in Roger and Stan.  Stan, I still have the 'little brother' casting aging under the workbench too once the P&W is completed. I am sure Todd will keep a set warm for you :).  Did he send you an updated set of plans, since I recall you did buy the plans at last years CF show. It's been a most enjoyable build so far but I still have a long ways to go. Like Chucks signature line says...."so many projects...so little time."  At least until I can retire !!

A few more little bits over the last couple of days. First is the pushrod (photo 1). This is just a length of .125" drill rod threaded on one end. There will be a notch at the other end but that is located and machined at assembly.

Next up was the link pin. This is a simple turning operation with threads on both ends...2-56 on the small end and 4-40 on the other (photos 2 & 3).

The link rod is again threaded 5-40 on both ends and then a double bend of 15 degrees to make the offset. After doing a little trig to find the overall length needed, I threaded both ends (photo 4). In order not to mess up the threads I cut two pieces of brass  tubing to fit over the threads (photo 5) and held this in the vise to bend to the 15 degree angle, checking it with an angle block (photo 6). The finished piece is shown in photo 7.

Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on January 24, 2016, 12:30:15 AM
The next part is the timing gear shaft which is also a turning operation for the most part. I didn't photograph the turning operation, but after cutting the part off the parent stock and facing it in to length in the lathe, I transferred the part and chuck to the mill and set up the slitting saw to put the slot in the face. The thread is 6-32 LH so I had to wait on the die to do this one. The finished part is shown in the last photo.

Bill
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on January 24, 2016, 12:47:32 AM
Finally, I got a start on the links. For the moment at least I am going to make these from brass since I had some square brass on hand. After milling it down from .250" to .188" square, I turned, drilled and tapped the shank on the first length, then parted it off to do the same to the second link (photo 1). The two blanks are shown in the last two photos so you can see there are a few more things to do yet to finish these up. That will be on tap for tomorrow.

Bill

Note to Todd if you check in. On the Pivot Yoke, if you drill to the call out depth of .375" its mighty close to breaking through to the slot!  I reduced the drill depth to .250" on this part. There is more mean on the Yoke so I did drill to .375" there.

Post by: b.lindsey on January 25, 2016, 12:04:13 AM
One more thing done this afternoon. From the supplied gear stock, I machined the hub of the timing gear, drilled and reamed it to .188" and parted it off. After reversing it in the 3 jaw I faced the other end until the overall width was .250". This is shown in photo2 1 through 3. I then located the center of the timing gear shaft and drill #56 through both the gear and the shaft. Another hole the same size was drilled .250" further out. The inner hole is obviously to secure the timing gear to the shaft and the outer is for the pin which is engaged by the starting crank. I took an extra #56 drill bit and used the dremel cut off wheel to cut two .313" pins from the shank portion and then loctited these into the previously drilled holes. The last photo shows the timing gear assembled to the shaft and the secondary pin for the crank handle.

Shouldn't be a long delay though. I also want to go ahead and get the cam gear made up too. Something to attach a couple of the previously made tiny parts too before the gremlins grab them.

I fully understand about not always being completely happy with the parts we make; we can be our own worst enemies.  But if you don't challenge and push yourself to do better what's the point? You just end up making more of the same old thing over and over. I think we have talked about this on the forum before; I'm doing things today that I would have never dreamed possible 5 or 10 years ago.

In the end we just need to do what makes us happy in this great hobby that we have.

Over the last week I took the wood base to work and applied several coats of Minwax Polyurethane Gloss finish to it (temp and humidity in the garage aren't condusive to it this time of year at home). With that done, I brought it back home and located the holes for mounting the bronze engine base to it, applied tape to both the top and bottom sides to prevent any splintering and drilled clearance holes in the two cross pieces. The base was then temporarily mounted to it with 5-40 hardware. so that is done and shown in the first 3 pictures below.

Had a little more time this evening so also got a start on the timing gear. Faced it, turned the hub, then drilled and reamed it. After parting it off the gear stock, I flipped it around and faced the other side to the overall thickness needed and then checked the fit of the timing gear shaft shown previously. It fit like a glove and looking at it from the hub side, the shoulder of the shaft extends just .001 or .002" beyond the hub to give it some running clearance. I still need to drill and tap two holes in the face of the timing gear but that will require a rotart table set up on the mill and didn't have the time for that tonight. The last four pictures show what was done so far though.

Zee, a short (but long enough length) of gear stock for both the timing gear and the crankshaft driving gear (I think I called that the timing gear in an earlier post by mistake) are supplied with the casting kit. I believe they are both cut from 12L14 stock and machine beautifully. The only issue I had on this larger timing gear was that I couldn't get it centered in the 3 jaw chuck, the jaws grabbed two teeth at the peak and one valley between teeth. Just switched over to the 4 jaw to machine the hub and do the drilling and reaming so I could get it centered well enough.

Hello all,
I purchase the gear stock (actually called pinion wire) from Stock Drive Products in 5' lengths.  They list the material as "carbon steel;" however, I'm pretty sure it's 12L14 leaded, screw machine steel.  With the hubs, stock gears were out.  Pre-machined gears would have cost me about $35/set so they were out as well.  We felt the gear stock was a good compromise as it fills the goal of not having to cut your own gears and fits in the project budget.

The original kits called for brass, hubless gears with the driver adhered to the crankshaft via Loctite.  Adding the hubs for stability (in the case of the timing gear) and security (in the case of the driver) are among the changes I made along the way before re-releasing the kit.

Although holding directly in a lathe chuck works, a better way to hold the stock is with a collet or a ring.  The driver's od is 3/8" and holds nicely with a collet.  I machined a ring to hold and protect the larger gear.  Accurately bore a hole thru a piece of 1" stock, insert gear stock, tighten the chuck a little to secure.  The small machined section around the outside of the ring is used to indicate and be assured all is centered well.  See pics below.

Incidently, I didn't bother with a rotary table for the tapped holes for the pushrod crankpin or the timing button, but centered the gear under the mill spindle with an edge finder.

Enjoy,
Todd.

Not much to add tonight, but I did get the timing gear drilled and tapped for the pushrod crankpin and the timing button. I did use the rotary table and both drilled and tapped these two holes using the same setup so that the threads (especially for the pushrod crankpin would be perpendicular to the gear itself. A couple of pictures of the set-up and the final results are shown below.

Thanks Hans!! Zee it called a timing button. I really haven't gotten into the "sparky" parts of this engine yet and will likely end up using the S/S CDI system so it may not even be needed. If not I assume it will be replaced with the magnet for the Hall sensor, but again am not that far along yet. At the moment it is a 1-72 cap screw whose head has been rounded over. If I end up needing this, I will likely make one from steel so as to avoid the dimple, or a 1-72 hex head screw and machine/round its head. Just didn't have one of those on hand out of steel and don't fancy buying 50 or 100 from Micro Fasteners to use only one.

I was out of town last weekend so didn't get a lot done in the last week but should make some progress today. I have ordered some 3/8" round bearing bronze to remake the links, but before re-doing them I made the third larger link this morning that fits on the cam gear. Mostly just some turning work and a bit of milling but nothing special. The pictures below show this part. Hope to get more done this afternoon before the Big Game.....go Panthers!!

You must be getting closer to completing Bill? I been seeing some fiddly bits getting done. But progress is progress no matter how small and she's shaping up. Did the gear come with teeth already for trimming or did you cut them? Another question about the Chuck in the vise, what is holding it?

Don
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on February 07, 2016, 04:23:19 PM
Still a long way to go Don, but yes, still making some progress. Even the little bit do add up. The gear stock came as a length of what is called pinion stock, teeth already cut, just had to machine the hubs, bore, etc.  I have two adaptors for the lathe chuck, one is 6 sided, the other is 8 sided. Both screw into the back of the chuck and then can be indexed in the mill vise. They are very useful for many things and are a standard Sherline accessory.

Kim, I still have most of the castings to go yet. I have been concentrating on some of the smaller parts since they are ideal for the Sherlines and I can work on them in shorter spurts of time and still complete them. Nearing work on some of the castings though. The flywheels are the only other larger ones that will require the larger lathe at work.

I did finish up remaking the links this time starting off with some round bronze bar. I am much happier with this set. Didn't take any new pictures since the procedure was almost the same but below are a few pictures of the newly finished set of links.

Back to work on the collars, one of which I had messed up if your recall. This time I will be doing them together as a pair after the initial machining.  This morning I got the inboard side of each collar machined and fit as closely as possible to the diameters of both the cylinder and water jacket. Didn't take a lot of pictures of the machining as it was straightforward in the 4 jaw chuck. The last two pictures show the fit up of how these pieces will fit together to form the water jacket around the cylinder. Now it's on to machining the back sides of both collars, the final OD (where I messed up before), and then some drilling, tapping and final clean up of the "ears" on either side.

Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on February 27, 2016, 10:11:53 PM
Got the collars pretty well finished up today except for tapping the holes and this time it went better. These guys  have a good bit of work to them so I am glad to get them behind me. In photo 1 I was drilling the two holes for the rods that hold the whole assembly together. I use the rotary table and lathe chuck to hold the collars as shown. Once this was done for each collar individually I sanded the back sides of each one smooth then butted them together to hold them in the mill vise to trim off the square end as shown in photo 2. With the same set up I milled both sides to bring the overall width of the tangs to size (photo 3). Brackets will attach to these points with 2-56 screws so the next step was to drill the holes for tapping (photo 4). Since these holes break into the previously drilled hole for the rods, I did have to drill them from both sides. Todd suggests in the plans to drill these holes first before the larger cross hole for the rods, and I did that on the first attempt but actually prefer doing it this way better even if it took a bit more time.

The front collar only gets a hole pattern where the cylinder head will eventually attach so that was done next...back to the rotary table again and using the lathe chuck to hold the collar. To get the locations as precise as possible, I set the rotary table to zero and then used a square against the column of the mill to locate the part before tightening it in the chuck (photos 5 & 6)

Bill
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on February 27, 2016, 10:18:51 PM
So far so good...but this is where I went awry last time...cleaning up the OD's of the collars. I was more careful this time and with much the same set-up as shown above, I got both cleaned up to the correct size (photo 1). As you can see I had marked the front and back collars with an F and B mainly to avoid drilling the bolt hole pattern in the wrong one since there are slight differences between the two. The last two photos show a family shot of this sub assembly. The end of the rod still needs to be threaded 8-32 and I still have to make the second rod as well but that will go pretty quickly on the lathe. Thanks for looking in.

Bill

Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on February 27, 2016, 10:42:17 PM
I could have eyeballed it and come close Zee, but the square was easier and likely a lot closer than my eyes. I didn't want the cylinder head to end up at some wonky angle however small :)

The cylinder certainly turned out well Bill. I like how you blended the OD of the rings to the tangs. Always a bit of pucker factor when you tear into a major casting and have a bunch of hours in it...your careful persistence shows in the end product. Paul

Thanks for checking in guys. I did get all the tapping done on the collars so that was a relief too. They are done now. I did some roughing work on another pair of casting but no pictures of that to show yet. Also played around with bending the blue tempered spring steel and that went pretty well actually. I need to shear off some pieces closer to the width dimensions I need tomorrow at work so more to follow on that front as well in the next day or so.

Today I got the two cylinder supports done. The top part of the castings was slightly out of round but I managed to find a location in the 3 jaw chuck that worked so that the through bore looked fairly centered. Before doing that though it dawned on me that the mounting plate at the bottom is .064" shorter than the round top (lengthwise or .032" per side). Once that light bulb went on I figured I could machine the base plate and then back the carriage off .032" to machine the end of the round part in the same chucking, before turning the casting around and doing the same to the opposite end. This is shown in photo 1. With that done I center drilled and drill the .166" through hole (photo 2). The critical dimension is the length from the bottom of the base to the center of this hole, so transferring the casting to the 4 jaw chuck I first machined the bottom flat and then took it out to make this measurement. In order to get the casting back square each time I had to take it out for measurement, I used the 90 degree sides of an angle block to check it both vertically and horizontally as shown in photos 3 & 4. Once this dimension was reached I machined the inner surface until the .130" thickness of the base was reached (photo 5). That being done, all that was left was to drill the two mounding holes in the base and do some clean-up (photo 6).

Cool Bill and glad to see progress. I do have a question about the hole. You drilled the hole before milling the flat, how do you know how true the hole is to the bottom? Would it have been better to mill the bottom and clamp it to an angle plate and then drill the hole? Just talking out loud here and nice work buddy...... :ThumbsUp:

Don
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on March 06, 2016, 07:17:30 PM
Don, there was plenty of material to be taken off the bottom of the base so once I got down to flat metal, I measured from the bottom of the hole to the bottom of the base. Slight adjustments could be made in the 4 jaw as needed and this got me within a couple of thousandths as measured from each side. A little fine sanding on the surface plate at the end and both are well within .001" which should be more than close enough.

Thanks Mosey, I have had a few errors along the way also though, and the cast parts aren't all that shiny, but several members here have been most helpful in sharing their finishing techniques and procedures as far as machined parts,  though I still have a ways to go.  Thanks for looking in.

Not a lot to add tonight but some hex head screws came in today. The shortest I could order were 3/8" and I needed 1/4" so I had to cut them off. Someone was talking about this the other day and since I only needed four screws, I took a scrap piece of 1/4" brass and drilled and tapped a hole, screwed the hex screws in and milled off the excess on the other side.  These were used to affix the "deer whistles" to the main frame. The other thing I did last night was to make some brass nuts to clamp the cylinder assembly all together on the support rods. Just a few pictures of this small progress follow.

Slowly Don, but still a smidge of progress. It will look better once I get the head on it but at least the cylinder assembly is attached for the moment. Thanks for following along my friend and for your support.  BTW, I ordered another batch of micro-mesh sanding thingy's today...I love those things!!! Now...a while back, you and Cletus were talking about Moody open end wrenches for hobby sized work. Do you have a preferred vendor that you have used before for moody tools?

That might be an option Mosey. I made these with a much more  rounded head and a small undercut on the bottom to make a round bearing surface. I will see how they look as things progress more and once the head is added. Easy enough to change down the road if need be.

Hello Bill et al,
Remember that the side rods take all of the explosive forces.  The brass nuts are pretty, but make me a little nervous.  On the prototype I used a pair of SS small pattern nuts on each rod.  That's also why I left the rods a little long.  Let me know if you have any trouble finding fasteners.  I buy them 100/box from McMaster and Amazon.

Keep up the good work.  The engine is looking GREAT!

Todd.

BTW, I was just about to update the drawings with the new part name.....  :-) 
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on March 11, 2016, 07:01:18 PM
Thanks Todd, you make a good point. I do want something more than just two standard nuts though, and you are right there is a generous amount of thread exposed for that purpose. Maybe a larger pattern steel hex nut and then as Mosey suggests an acorn style nut to act as a locknut and finishing touch.

Bill

Post by: littlelocos on March 12, 2016, 01:07:31 AM
Bill,
I did some quick calcs this evening and, assuming your brass nuts are 1/8" tall they should be at least as strong as the 8-32 steel threads.  Using a base diameter of 0.1257 and a UTS of 60ksi yields 744lbs.  Using shear strength and pitch diameter of the brass threads yields about 2,000lb/each.  (1/8" tall yields shear area of 0.0607 sq in.  360 brass has shear strength of 34,100psi)  Assuming an ultimate cylinder pressure of 500psi at ignition (somewhat high given 4:1 CR) we have a force of about 300lb to deal with and thus have a factor of safety of about 4 on the rods.

In short, the brass nuts should be fine.  :-)  I could do some closer calcs if needed.
Enjoy,
Todd.

BTW, the original line drawings show heavy-hex nuts on the rods.  See pics below.

I have been piddling around lately with some .010" blue tempered spring steel stock for the 7-8 springs required for this build. I sheared the stock on the sheet metal shear at work to get good clean edges. First up was the exhaust spring (one of the more difficult ones). After several false starts, errors, screw ups etc. I think I finally succeeded though that may not be fully known until final assembly. Todd provides some .010" spring wire with drawings for alternate sprint  styles so that remains Plan "B". Anyway after annealing the sheared stock I punched the 1/8" hole required (photo 1). I had made a mandrel to bend the "U" around and this worked well enough. I finally got the ciphering (math) right after a couple of missteps there (photo 2). After cutting off the longer leg even with the short one I used a rotary diamond plate hone to round the ends to the proper radius. (photo 3) and used the dremel with a cut off wheel to slot the bottom leg. This last  photo was actually taken of a previous try which later failed due to improper tempering after heat treating. I inserted a 1/8" dowel pin into the hole to heat the spring cherry red with minimum heat sink and quenched it in oil (photo 4). With that done, I used the propane torch to reheat until the spring was just turning blu-ish and then let it air cool. The final result is shown in pictures 5 & 6. After repeated pinching of the two legs together it seems to return to its original form and with a good springiness to it so we will see it if works down the road. On a part this small and thin this is really some seat of the pants metallurgy (or metal urology as my former student said).  I had mentioned in an earlier post the need for some better open end wrenches...which arrived today from Amazon. Nice looking tools and they work much better than the cheap imports they are replacing. More on spring making tomorrow.

Post by: b.lindsey on March 12, 2016, 01:47:50 AM
Thanks for the calculations Todd. Better safe than sorry though. At the very least I think I will remake the nuts out of steel or still explore the option of nuts plus lock nuts so there is no chance of them loosening over time and. As I had said earlier, I just want something a bit less plain the two standard nuts.

Bill,
10-4 on the calcs.  Great job on the spring.  That part must've been a problem on the full size engines as well.  The design for the alternate spring first appeared in the 2nd edition of Gas Engine Construction after a paragraph that started "As the flat steel spring shown in Fig. 113 is somewhat difficult to make, the builder can substitute a spring of steel piano wire...."

I love the description of quenching and tempering the flat valve spring.  (see below)  Congratulations on completing the spring!

Enjoy!
Todd.

Two more springs made this morning. First the governor tension spring which only required a 45 degree bend on one end so didn't even have to anneal the spring stick. That is shown in photos 1 & 2. Next up was the governor retainer spring which required two 90 degree bends so this piece was annealed then drilled and bent (photo 3). After heating to red and quenching, I decided to try the method described in Todd's post last night. Repeated three times as described and seemed to work well (photo 4).

Zee asked for a family shot last night as well so here it is in photo 5. Several of the parts shown were made up from multiple other parts so there is more there than it appears.

Finally I got a start on the cylinder head bringing it down to the correct OD. It will remain in the 3 jaw chuck for several additional operations on the mill, but more on that tomorrow I hope (photo 6).

Bill

Edit: picture 4 is now showing a picture 6.  The original file gave me the file server error so I resaved it and it worked, just out of order.

Post by: b.lindsey on March 13, 2016, 12:33:51 AM
I had ordered some pyrex tubing this week and it came in todays mail so this afternoon I diverted to see if I could come up with an oiler for the back end of the cylinder.

After using the dremel with a cut off wheel to cut off a piece of the thick walled tubing to apprx. .800" , I used the diamond hone again (photo 1) to clean up both ends until they were square and smooth (photos 2 & 3). This was a slow process but I liked the results. The it was back to the lathe and some brass stock to begin forming the base, designing as I went along. I bored the top side until the tubing just slipped in (photo 4). The tubing is 16mm OD with 2mm wall...pretty stout stuff. Then I turned it around to form the bottom side (photo 5). For the central tube I cut of a piece of 3/16" OD brass tube to a suitable length and threaded both ends 3/16"-40. The upper side of the base was drilled and tapped for one end of this tube but to limit the amount of oil going through I plugged the bottom of the tube and drilled a #60 hole in it. This plug only extends into the tube about 1/8" or so (photos 6 & 7).

Bill
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on March 13, 2016, 12:48:55 AM
The I took a piece of mild steel and began forming the "valve" (photo 1). I had previously threaded the ID of the brass tube 6-32. The head was then knurled (photo 2) and the point sharpened to seal off in the #60 hole in the upped end of the brass plug at the bottom of the tube. After cutting it off and chamfering the head the valve is shown in photo 3 finished. The last photo gives some idea of where it stands now. I still have to make a top, cross drill the lower end of the tube so oil can enter it and go down through the valve, and make some gaskets for both the top and bottom of the glass piece. I'll see how it looks tomorrow. It's a smidge large but I think once the 5" flywheels are in place and all the other monkey motion, governor, etc. is attached to the near side of the frame, I don't think it will be a distraction. Once I get it finished tomorrow I put some oil in it an see if it even works. It doesn't show in the pictures (I'll take one tomorrow but the nipple on the bottom of the base piece where it attached into the cylinder is milled on both sides so you can see into the drip chamber to make sure it's working in operation. That is about it for todays installments.

I like your description on making springs. I've always had trouble with doing that.

Concerning the nuts on your rods I have always used a thicker nut like would have been used back in the day. The supports for your cylinder will take most of the shock. On a couple vertical half scale models I've built I could actually see the support rods bend when the engine hit.

I finished up the oiler today. First picture is all the parts to it. Then the assembled oiler, and third the oiler in place and shown with the flywheel castings. I did give it a try and it works and is controllable as to the time between drops so I am happy about that.

I also remade the nuts for the cylinder rods...not as esthetically pleasing but not just plain nuts either. Since I didn't have any 1/4" hex stock on hand other than brass, I made my own out of some drill rod. These are 3/16" long and should do the trick. The last two photos are of these.

Beautiful oiler. The family is growing. This is such an interesting looking engine, especially the horizontal version. Following along at each step. I do like the heavy nuts.
BTW, when I made oilers for the ľ horse, I chucked the glass tube in the lathe (5c collet) and use a Harbor Freight diamond wheel mounted on the Foredom hand piece in a shop made QCTP holder.

Don, you are right its big...the more I look at it the more I think too big. I was a fun exercise and I think I can now make another on in half the time or better, just scaled down a bit. I have sourced some 12mm OD by 1mm wall tubing that may be more to scale so I am thinking of ordering that. Stan what size did you use?

Its hard to tell until you see the whole thing put together and in place.

Bill you might get away with shortening the existing glass tube and maybe thinning the top and bottom plates which would reduce the overall size of what you have before making a complete new one.  This one (http://img.photobucket.com/albums/v156/jasonballamy/Hit%20n%20Miss/1-3rd%20Scale%20Allman%20c1890/DSC00942_zps43nljegb.jpg) is the same diameter but the reduced height makes it less imposing.

Having said that I have used 1/2" tube on an engine with a smaller 5" flywheel like yours and that looked about right with the same height proportions as the one above.

Post by: b.lindsey on March 15, 2016, 12:14:16 AM
Didn't have much shop time this evening but had taken the length of brass tube I acquired for this project to work to cut off a 5" piece to form the combined gas tank, coolant hopper. The cut off piece sanded smooth on both ends stands 5" tall for the sake of size and is 1.375" OD tubing (photo 1). Then I turned a plug to form the baffle between the two chambers to a very snug but not press fit and tapped it in until it reached the proper depth from the bottom end of the tube (photo 2). Since this isn't a pressure chamber of any sort, I used the low% silver solder from PMR (the same as supplied with their boiler kits). The purpose was only to seal the joint so the cooling water in the upper chamber won't mix with the gas in the smaller lower chamber (photo 3). After soldering I did a light leak test, blew in one end to see if there was any air leaking, and finally a water test to see if there was any seepage through the solder joint. So far so good.  Now I need to drill the holes for the filler tube and gas out lines on the lower gas tank chamber and the inlet and outlet tubes in the upper coolant chamber. I also need to cut a slice off of some 2 1/2" brass to machine the base that this tube sits on and which gets attached to the wooden engine base. More tomorrow...

Not  even a full ring Don, I cut three pieces about 1/2" long each and laid them around the joint 120 degrees apart and then heated. Once it began to melt it flowed perfectly. Remember this is a fairly low temp solder with like 4% silver and is a breeze to work with. It will be used for soldering in the various tubes as well. Thanks for looking in my friend.

A few more steps done tonight. I set the base up on the rotary table in the mill to drill the four mounting holes 90 degrees apart (photo 1). Then back to the lathe to turn the final OK and thin the base down to .125" (photo 2). The result is shown in photo 3 and where it will fit on the engine base in the last photo. All that is left is to mill out the spaces between the four mounting lugs and round the ends of those. More tomorrow. Oh the 12 mm tubing arrived today also!!

Don, I should have noted (not that you can't tell already, the brass tub has not been polished at all yet. I will do that once I drill the several holes in it for the tubing, and to locate one of those holes I needed to have the base finished. So, it will look better soon.

Most of my tips on polishing I  have gotten from Don. I'm still a newbie on that front. Jim, I don't recall a specific thread on it which is why a search doesn't turn it up. There was some discussion though as I recall in Don's E&A build log so you might glance through it. I have said before that the MicroMesh sanding sticks were a huge help and Don put me on to those as well though they are cheaper buying them direct from the MicroMesh folks. This is the product I am using  http://micro-surface.com/index.php/products-by-type/dual-angle-detailing-files/dual-angle-micro-mesh-regular-files.html

Another "tool" I love is the Foredom bench lathe:  http://www.foredom.net/blbenchlatheandkits.aspx  A bit pricey but a high quality too in a small footprint hobby size.

Maybe we can persuade Don to start a thread on this topic.

Bill thanks for the vote of confidence. I am not by far an expert on polishing but for my engines I get good results with my process. I am sure there are some who could do it better then I. This is a link to my E&S thread at the point where I showed my sanding and polishing setup. I do have the buffer missing and my finishing station as well as my Foredom with some of the attachments. I will try to put something together for you Jim and take a few photos of some of my equipment that I use. Here is the thread and look for reply 105.....http://www.modelenginemaker.com/index.php/topic,4629.270.html

Thanks Don and Bill. Each of your posts have already been quite informative. I'll look forward to the next installment.

Don, I remember looking at your beautifully finished E & A project the other day. It'll be nice to learn a little more about how that was accomplished.

Been working this evening on the new smaller sized oiler. No pictures tonight but will have some for you tomorrow. Have to work a recruiting event half the day though. The new junior version is looking much more to scale though I must say. Pleased with it so far.

No more work on the junior oiler today but still have a couple of pics of what has been done for comparison. First up this afternoon though was to drill the tank for the five nipples that will be soldered into it. These were located, drilled and reamed to size (photo 1) and then fitted together and in place (photo 2). I still need to finish up the base for the tank tubing and will do that tomorrow. The new base for the smaller oiler is shown in photo 3 as I hold the original oiler next to it. In reality the new oiler looks even smaller by comparison. The last photo is of the new oiler for scale comparison on the engine frame. I still think it about right but will need to finish the other components to finish it off tomorrow as well. Also the height of the new glass piece is going to be reduced further, its still a little too tall I think.

Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on March 20, 2016, 03:31:17 PM
Jim, the two 3/16" nipples on the upper end of the tank are for the coolant lines to and from the water jacket. The 1/8" nipple directly below those two is at the bottom of the fuel section of the combined tank(s) and is the fuel out connection to the mixer. On the opposite side of the tank but still in the fuel section there are two 1/8" nipples side by side. My assumption is that one is for filling the fuel tank and the other provides venting during the fueling operation as well as an overflow outlet. Otherwise fueling would pressurize the tank. That's my take on it.

Post by: b.lindsey on March 20, 2016, 03:47:01 PM
So far today I have been working on finishing up the tank base/mount. I centered the rotary table on the mill and with the base upside down in the lathe chuck I mounted it to the RT. I used the small Starrett square against the vertical mill way to line up as close as I could eyeball two 1/8" pins in the mounting holes (photo 1). It turned out that the mill table was at 196 degrees and the plans call for a +/- 29 degree rotation (using a 1/4" end mill) to each lug. Just to keep me straight, I wrote down the 196 degree position and the other three positions 90 degrees advanced from that to define the center point between each pair of lugs. Then I added and subtracted 29 degrees to each center point to define the limits of rotation for each of the four sides (photo 2). I milled about .015" per pass working all the way around until the final finished diameter was reached. In total .188 was removed from each arc. The result is shown in photo 3 and as can be seen in photo 4, the base now fits neatly within the width of the wooden crosspiece it will fit on. Still remaining is to round over each of the lugs.

I think the cone in the bottom helps to keep the bottom empty when it gets there. No lingering of fluid in the bottom of your tank, because the is not enough surface area to settle.

A shame your sherline doesn't have the provision Bill, sure makes life easier.

Other than lightening the part, it's purely "decorative".

If it were a casting (and it may someday be), it would keep the section thickness uniform and prevent shrinkage voids.

Bill,

I don't know this for sure, but I think the hand wheel on the RT could be replaced with a zero resettable hand wheel.  I'll call when I get a chance and find out.

Jim
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on March 21, 2016, 12:12:46 AM
Jim, it isn't the handwheel that is the issue. I think what Don was referring to in a resettable ring on the table itself that can be reset to zero. In the case of this part, when I got things lined up the degree mark was on 196. These index marks are etched/engraved into the table. It wasn't a problem just makes for an oddball starting point but that is why I did the math and wrote it down, so I would know the start/stop degrees for each quadrant.

This afternoon, I finished up the new smaller oiler. I am much happier with it.  No machining pictures as the processes were the same as for the larger one but I have included some comparative pictures below. See what you think. The second and third pictures are the old (larger) and new (smaller) mounted on the engine from approximately the same perspective. The last two pictures are strictly of the new oiler.

Thanks Chris. Still not perfect but I am living with this one for now. I think it will fit in better when it isn't stuck up there alone. The central brass tube is down to 1/8" from 3/16" on the larger oiler. The threads on the needle valve are now down to 1-72. Not sure how much smaller I can scale it.

Bill
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: crueby on March 26, 2016, 12:17:46 AM
The oiler is controlled by the needle valve, which drips oil down through the pipe with the opening on the side? What keeps the oil from just running out the side? I've seen them in pictures but never dug into how they work.

Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on March 26, 2016, 12:49:35 AM
Chris, there is a small cross hole near the bottom of the pipe inside the glass. The valve seals below this cross hole. When the valve is opened slightly, oil goes into the cross holes, down through the bottom cover, and in this case into the set screw used to attach the oiler to the cylinder. The set screw has been drilled through (#60), so oil can then very gradually enter the cylinder. If the flow (drip) is small enough, it doesn't seem to run out the side of the viewport holes at all.  Is that confusing enough??  ;D

Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on March 27, 2016, 02:20:05 AM
As, planned, almost all of today was spent on machining the head casting. After turning the main OD as shown in a previous post (before I got diverted on the oilers), I had left the casting chucked in the lathe chuck for the further work. To begin I located, center drilled, drilled and reamed the two holes for the valve stems and just cleaned up the ends of the holes to make them flat (photos 1-3). I then had to reset the rotary table to a vertical position and figure a way to make sure the two valve stem holes were both horizontal to the table. I did this by inserting two 1/8" dowel pins into the holes and using the caliper as shown in photo 4, adjusting the rotary table until the two pins just touched the caliper jaw equally. With that done the dowel pins serves a second purpose by allowing me to use the edge finder to locate the center of each valve stem hole in order to drill the intake and exhaust port holes. This is shown in photos 5-7. Rotating the table 90 degrees I did the same for the other port hole as shown in photo 8.

Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on March 27, 2016, 02:33:25 AM
Next up was drilling the hole for the rocker arm pivot pin (photo1) and cleaning up the pivot arm to the proper width and height below the exhaust valve stem hole (photo 2). Photo 3 shows the mixer body, and exhaust pipe in place awaiting a 90 degree ell fitting to attach the muffler.

The excess material on the back of the casting still had to be removed and to do this I made a small fixture (photo4) to insert the head casting into in order to machine the back off leaving a register ring to push fit into the end of the cylinder (photo 5). The live center was used to keep the casting secure in the fixture which was machined to a close fit to the head casting OD.  Photo 6 shows the head bolted onto the cylinder again with the mixer body and exhaust pipe in place.

Looks Good Bill. Thanks for the great explanation.

It looks like it was somewhat of a project just to make the fixture to hold the casting in order to remove the unwanted material off the backside.

Are there any instructions that came with this project or are you just having to work from drawings?

Jim
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on March 27, 2016, 03:05:11 AM
Jim, I am just working from the drawings. Todd does supply a CD of photos with the casting kit which helps on some parts, but not any detailed machining instructions. I am just kind of figuring out what works on the Sherlines as I go along. The little fixture was about all I could do in this case as there is so much sticking out in the outboard side of the head casting. Obviously with a larger lathe, the jaw depth would be sufficient to just hole the part in the lathe jaws....not so with the Sherline chuck...just not enough depth there. That's the fun though of castings and working with smaller machines :)

Thanks Kim!  I got a few more fiddly bits done today, but not set-up or machining shots. I got the rocker arm made with a few dimensional changes from the plans to better match the cylinder head geometry, the rocker arm pin, and the tappet. I would show these assembled, but I loaned my only 4-40 tap to my senior design group at school and won't have access to it till tomorrow. I need to order a couple so I have more than just the one. Photo 2 is where I had screwed the pivot pin into a 4-40 tapped hole I had on hand in a piece of brass just to check that the rocker arm swivels as it should.

A few pictures of todays parts are attached below.

Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on March 28, 2016, 01:46:36 PM
Thanks for looking in Jim and Achim. Jim the rocker arm was pretty simple and made from a piece of 1/4" square brass. As I noted earlier one aspect of the head geometry seemed off to me. The plans call for the top of the rocker arm bracket to be .110 below the centerline of the valve stem hole. I though I had this dead on as I had oriented the valve stem holes vertically, found the center with an edge finder and then used a 3/16" end mill along the top of the rocker arm bracket. That should have put the surface at .094" below the valve opening, so I stepped close by .016 to take another pass which should have put it at the .110" dimension. From there I cleaned up the underside as well. After looking at it afterward it didn't appear to be .110 at all. All I can figure is that may have only moved the edge finder .050" instead of .100 to locate the center of the valve stem opening thus putting the rocker arm bracket .050 higher than called for.  Not wanting to redo the entire head, I just decided to "adjust" the "pads" on either end of the rocker arm by lowering them relative to the mounting surface. Ideally the rocker arm should be symmetrical about the centerline. It looks ok on the valve stem end now, won't know on the tappet end until I get a bit further along. Worst case is that I may have to remake the rocker arm again, but that is far less demanding than remaking the whole head.

All I can figure is that may have only moved the edge finder .050" instead of .110 to locage the center of the valve stem opening thus putting the rocker arm bracket .050 higher than called for.  Not wanting to redo the entire head, I just decided to "adjust" the "pads" on either end of the rocker arm by lowering them relative to the mounting surface. Ideally the rocker arm should be symmetrical about the centerline. It looks ok on the valve stem end now, won't know on the tappet end until I get a bit further along. Worst case is that I may have to remake the rocker arm again, but that is far less demanding than remaking the whole head.

Bill

Thanks for the explanation Bill. I'll be looking forward to , as they say, "the rest of the story" as you get further along.  :)

Before I can finally settle things on the rocker arm, I need to make the front and back pushrod guides that fit the square extension off of the cylinder collars. The 3D view of these is shown in the first two photos. Though some suitable pieces of bronze are supplied with he casting kit, I elected to cut a couple of pieces off a piece I had on hand. Tonight I got a start on the back pushrod guide by  milling the piece of bronze down to the overall dimensions required for the finished part (photo 3). Since two of the dimensions are really close I oriented it correctly and sketched out the outline with a  sharpie just so I wouldn't do any further machining with the wrong orientation (photos 4 & 5). More on this and the other guide tomorrow and over the weekend.

Just a couple of baby steps this evening.  Milled out the gap where the back pushrod guide fits to the collar (photo 1), drilled and reamed the through hole for the pushrod (photo 2), and did a trial fit to the collar (photo 3). Tomorrow I will drill the clearance holes for the 2-56 screws that mount it to the collar, and finish off the contouring as per the drawing, then start on the front guide.

Post by: b.lindsey on April 03, 2016, 01:16:17 AM
Well to start the morning off I finished up the rear pushrod guide and installed it on the rear collar (photo 1). With that done I set out to whittle the block for the front guide out of the oversized piece of bronze I had previously cut off for that purpose. Once I got it to size I did the drawing thing again (poorly I might add) just to keep things straight in my mind (photo 2). The next five pictures are just a sequence of milling out the various bits of metal that weren't a part of the guide.  There were a lot of set-ups on this little guy...not tricky at all, but time consuming as it took most of the afternoon to get to this point.

Bill
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on April 03, 2016, 01:22:12 AM
At the end of the day both pushrod guides are finished except for some rounding and clean up things and amazingly they both fit and with just a little polishing of the pushrod it fit and slides very well in the guides. Photo 1 shows the finished front guide. Photo 2 shows it installed along with the rear guide, and the last photo shows a bit of the governor mechanism in place as well though I still need to make the pin keep it in place.

Thanks all for today, doesn't look like a lot but as noted above, lots of tedious time consuming work and I am pleased with the results.

Thanks Dave and Zee. Its getting to the point where finishing up some of these "attachments" lets me also add some of those numerous little fiddly bits I had made earlier in the build, so its kind of motivating. I think tomorrow I will try to finish up the head. Drilling and tapping for the sparkplug and counterboring from the inside of the head for the valve seats. Or maybe the rear tie rod supports so that I can start hanging some of the flywheel/cam gear mechanisms on. Thanks for looking in!!

Thanks Don. The rounding wasn't all that scientific to be honest. Basically I pit a 1/8" dowel pin in the hole and let the pin rest on the vise jaws. Gradually rotated the part around and clamped it after each move and used a 3/32" ball end mill and very light cuts until it looked 'bout right  ;) As I said, not scientific but it worked.

Thanks guys!  I thought I had shown how I did the rounding in the first guide but I guess I didn't. There will be another occasion to do so shortly I am sure. Kim, the RT could be used but this in this case might have been more set-up than needed. The rounding is strictly aesthetic so doesn't have to be that spot on as long as it looks decent.

I did get the pin made this morning though it took two tries. Nothing special there but there are a few pictures below. You can see in the last picture that there is a gap between the head of the pin and the pushrod guide. this will be filled in by the governor arm outboard mounting lug. The inboard mounting lug will fit in the gap of the center piece thingy (the one with the roller) :)

Thanks Charlie, Zee and Cletus.  Zee, the first pin was a bit tight in the pushrod guide holes and I buggered up the slot some trying to get it in and out. Since I had already parted it off it was all but impossible to chuck it up again and polish a few tenths off of it. So I just made a new one and checked the fit PRIOR to parting it off. Should have done that the first time. The slotting saw works well. I just touch the lower side of the blade to the top of the screw....lower it by half the thickness of the saw blade, and then lower again by half the diameter of the screw head.

A couple had asked about the rounding procedure. This isn't as good an example, but I made a new rocker arm today as well (there was one aspect of the other one I wasn't happy with) and did the same things though it wasn't quite as long on rocker arm. The original square area where the mounting hole passes through needs to be rounded into as near a circle as possible. In this case I inserted a 1/8" pin, rested it across the vise jaws and set the cutter above the center of the pin by the prescribed radius of the desired circle. This its just a matter of taking cuts (along the y-axis), rotating the part a bit and taking another cut, etc.  Then I did the same to the opposite side. A little filing to smooth the resulting facets and its plenty good for a non critical job like this one. Maybe the couple of pictures below will give a better idea.

Yogi, it certainly isn't original with me. In fact I probably saw someone else here do it and filed it away myself. 

Achim, I meant to reply to your comment as to the fixations (screws) for the pushrod guides. Four 2-56 screws per guide...yep...I don't think they are going anywhere, but that is what the plans called for  :shrug:

Title: Re: Parsell & Weed Horizontal IC Engine
Post by: littlelocos on April 05, 2016, 03:18:54 AM
Bill,
Really enjoying the build.  Outstanding work!
The four 2-56 screws were an addition from the original plans which only called for two located on the top.  I added the wrap around and other two in fear that the two would work loose.  The full-size engine had two lower screws coming in horizontally; however, the size of the cylinder collar didn't allow room for that so I moved them all the way around.

I never cease to be amazed at the different ways to go about skinning a cat.  I did the pushrod bearings both at once and then cut them apart to finish.

I also use filing buttons for many of my rounded parts.

See pics below.
Enjoy!
Todd.

Title: Re: Parsell & Weed Horizontal IC Engine
Post by: littlelocos on April 05, 2016, 11:49:34 PM
Hello Mosey,
The filing buttons basically serve as guides to help produce flat sides and square corners.  They rotate as the file passes over, keeping them round and guiding the file over the part.  For small radii, this method works very quickly and is reasonably accurate.  The one photograph shows a rounded foot next to an un-rounded one.  Filing took less than 5 minutes per foot.  The part can be held in a vise or run along a flat file laid on the bench and using the button as a wheel.

Enjoy,
Todd.

Post by: b.lindsey on April 06, 2016, 01:34:11 AM
A few pictures I didn't get posted last night and a  new part started tonight. I had loaned my only 4-40 tap to my senior design group so couldn't tap the rocker arm support arm or the through hole for the tappet. Ordered a new 4-40 tap from amazon last week and they sent a 6-32 labeled as a 4-40. The replacement came in yesterday so I got that tapping done to show how the rocker arm looks in place. Good thing too, I was informed today by the senior design team member that obviously chose the short straw that my loaner tap had been broken. I kind of expected that to be honest so no big deal. Anyway that's what is shown in the first three pictures.

Then I got a start on the governor arm. The shape of the part is shown in picture 4. I started with a length of 3/8" square brass and milled it down to the required dimensions. I thought it would make the profiling easier to go ahead and mill out some of the unneeded stock like the gap between the legs but milled the entire length of the part (photos 5 & 6). While I still had a basically square part, I went ahead and located and drilled the holes as shown in the last two pictures.

Tomorrow I hope to turn the round end while there is still enough parent stock to mount in the 4 jaw chuck, and then the rest of the profiling can be done or that is the plan for now.

More done on the governor arm tonight. From where I left off last night, I milled off some of the material on the front end, leaving enough stock on the back end to chuck in the 4 jaw chuck (photo 1). With that done I turned the round section to 1/8" dia. as this is where the governor weight fits (photo 2). Next was to begin removing the remaining material leaving the legs (photo 3) then turning the part 90 degrees to do the same to the top leaving just the arm for the latch mechanism. The results for this evening are shown in the last two photos. I still need to round the arm and legs but that will have to wait till tomorrow and then do some finishing to get rid of the machining marks.  More to follow in the next installment.

Got the legs rounded on the governor yesterday. A little careful filing/polishing got the governor mechanism working freely. I have added one picture below of where this end of things stand at the moment. Still a bit of cleanup and polishing to the governor I needed but its close.

Kim, you really cant see it in that picture. It simply sits sandwiched between the governor arm and the lower support (the part that has the roller in it. The little finger screw presses down on the top of the spring to presumably adjust the sensitivity of the hit and miss action. Its stable as long as the engine is horizontal, but my work is that in transport, it could easily fall out.

It just sits there, fixed between the walls of the Governor Rocker.  I had to wonder about that one myself.
The full size worked that way as well.  See below.  For the vertical, a second spring presses against the back of the Governor Arm to hold everything together - including the main governor spring.

Enjoy!

Bill,
Glad to help!

If you look carefully, you can see differences between the governor on the Vertical I completed for Woody and the redesigned governor on the Horizontal you're working on.  The governor is one area I spent a lot of time on in the redesign -- mostly to make it look more like the prototype.

Also, on the prototype drawings I posted earlier, note the horizontally-facing bottom fasteners on the pushrod brackets.  I moved these around to the bottom in order to stay compatible with the original model casting sets.

Hello Mosey,
I angled the spark plug to take care of an interference issue on the original kit and still remain compatible with the original castings.  The full-size engines used separate valve cages and a built-up spark plug.  In this scale, the head becomes one casting incorporating the valve cages and the head "plate". 

Another alternative would have been to go with a tiny, 10-32 plug and leave it straight.

Thanks,
Todd.

I spent most of today working on one of the rear supports. I faced off the bottom using the 4 jaw chuck in the lathe and then turned the part around to turn the oil spigot on the top (photos 1 & 2).  Taking it to the mill I added the clearance holes for mounting it to the engine base (photo 3). In order to get some reference points for further machining, I made a simple fixture to mount the support in and proceeded to do the additional machining required (photos 4 & 5). After tapping the hole for the side rod, and the side hold for the cam gear pin, the support was mounted to the base (photo 6). I then checked the gears for proper meshing (photo 7) and finally added the linkages for the governor pushrod. After a few minor adjustments things seem to be working smoothly. The final picture shows things pretty much as they will be at final assembly.

Hi Bill, not an easy to make part. All machinings have to be acurate to the datum face and this started by this tiny casting. Well done and looking nice. This engine has more tricky corners than seen at the beginning.

Many thanks guys. I have found that there are several parts/castings that are a bit trickier that they seem at first glance. The other support should go a bit faster given what I learned on the first one. The trick will be to make sure they line up side to side so the flywkeeks won't bind. More to come today.

Post by: b.lindsey on April 17, 2016, 11:12:30 PM
I did make a little progress on the other support but changed gears to knock out a couple more fiddly parts needed for the governor mechanism. These were the two tiny latch pins needed for the rocker arm and governor arm. Each one has an 11 degree angle milled onto the end and a "v" notch filed into the side to provide a "catch".  To mill the angle I used the angle table with the 3 jaw chuck attached as shown in photos 1 & 2. The notch was just filed into the side of the part using a triangular needle file (photo 3). The finished part is shown in photo 4 and installed in the rocker arm in photo 5 though it should be shown sticking out of the top of the arm, not the bottom.

The mating part for the governor arm was done similarly but was hardened after machining as per the drawings. This is shown in photos 6 & 7 and installed in the governor arm in the last photo.

The two photos below hopefully show how the latch pins work...the first shows them in the locked position, and the second in the unlocked position, enabling the exhaust valve to close. The tolerances at this small size are very close. I know it is supposed to work but I will feel a lot better once I see it "working!!"

Thanks guys, haven't had any evening time this week so far, hopefully tonight though. The only good thing about these couple of tiny parts is that they are pretty simple so if I have to remake them for some reason its not a big deal. Got me thinking though about probably the smallest more complex part I have made was. I am thinking it was the crosshead yoke (the brass part in the below picture) for Jerry Howell's half scale Miser LTD sterling engine. Not just small but had have the opening in the middle of it for the mating delrin piece to fin and work smoothly. My recollection is that it was much like machining aluminum foil!!  :lolb:

I am still trying to wrap my feeble brain around this inertial governor system. Most of the videos I have found seem to be too jerky or to not focus on this particular part of the engines for long enough to really see what is going on. I did find one helpful reference here: https://books.google.com/books?id=pbdfmgEACAAJ&pg=PA43&source=gbs_selected_pages&cad=2#v=twopage&q&f=false  beginning on page 219. A snippet .pdf of the relevant pages is attached below and provides one of the better explanations of how this thing works though a slow motion video would be even more ideal!!

You may have to enlarge the .pdf to full size to see the drawings better, particularly Figures 122 & 123 which are the relevant ones.

Title: Re: Parsell & Weed Horizontal IC Engine
Post by: ogaryd on April 20, 2016, 04:18:03 PM
Hi Bill,   I've been working on this engine for a couple months and my opinion is the latch pins engage to open the exhaust valve at low RPM when the roller falls in slot of the .125 rod, at high RPM the the pins cannot connect because the roller moves to quickly past the slot to fall down, therefore the exhaust valve stays closed unlike what we're use to seeing with the exhaust valve held open in the miss cycle. Dose this make any sense? It sure doesn't seam efficient. Gary
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on April 20, 2016, 05:33:41 PM
Gary, yes it makes sense in a way. What I have trouble seeing is that given the weight of the governor mechanism I can't really imagine the roller NOT falling into the slot regardless of speed. When the engine is running faster that is when you want the roller to fall into the slot, thus locking the exhaust in the open position so you get a "miss" cycle. My understanding is that when the engine is running slow and needs to "hit," somehow the latch pin on the rocker arm must already have travelled beyond the point where it will latch with the pin on the governor arm. Just seems a bit counter-intuitive and why I say a slow motion video of it working would be helpful.

Thanks Chuck, I watch your vertical at the SC show and that did help. I am at the point of figuring out where the depression in the pushrod needs to be machined however, so turning it over by hand would be a tremendous help I think!

Bill
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: littlelocos on April 21, 2016, 01:21:14 AM
Hello all,
I'm working on a few diagrams and some written descriptions as to how the governor functions.  Should have the diagrams posted this evening.

Bill,  The roller definitely drops into the depression.  If the engine is running too slowly, the spring is stiff enough to allow the rocker arm (and counterweight) to rise to the point that the catches just miss each other.  When the engine is running fast enough, the spring flexes when the roller climbs out of the depression, leaving the governor arm down and allowing the catches to catch.  The whole thing works on the back stroke of the pushrod.

Adding to the possible confusion is timing the exhaust valve to open and close when it needs to and to have the pushrod open it to the point that the catches pass each other enough to catch when needed.

Here's a video from a builder in Iowa showing the engine running on the governor.  You may want to go to YouTube and switch to full screen for a better view.

Thanks Todd, I had seen that one and watched it a few times. Running at that speed and at that distance away its hard to see many details, but every little bit helps. I think once I get the flywheels done and added and can actually play with the mechanism more, it should make more sense. It obviously works and works well when set up right.

Post by: b.lindsey on April 21, 2016, 11:51:47 AM
Todd, your drawings and explanation help greatly. Judging by that though, it would seem that the front edge of the depression in the pushrod is the critical one from a location standpoint...is that correct? The rear edge would appear to not even come into play in the sequence of events. Many  thanks for taking the time to do this...it is a real help!! 

Bill
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: littlelocos on April 21, 2016, 12:39:17 PM
Hello Bill,
Glad to help.  The front edge is definitely the critical dimension.  I made the length of the pushrod adjustable to help with set-up.  The length can be varied in 1/32" increments and then locked with the nut.

Todd.

Post by: b.lindsey on April 24, 2016, 01:57:33 AM
Finally got the rear offside support finished today and was anxious to see how it would line up with the near side support finished previously. After a little fiddling and adjusting I got the both aligned to the point that I would insert a 1/4" piece of drill rod and turn it easily with a drill chuck...fingers were too slippery with oil to do it with fingers alone but it should be close enough. Tomorrow I will start either on the piston and rings or the crank or the valves, not sure yet which :) In the second picture below, it looks like the bore is a sloppy fit. After seeing the picture, I had to go check it again myself...what looks like a huge chamfer on the inner side of the bore is actually some oil seeping out. The supports still need a bit of fettling but they are close to finished.

A little shop time today, enough to make the exhaust valve (twice)!  Actually the first one was totally useable but I wasn't happy with the finish on the .125" section that slides within the cage (head). Much happier with the second one. Nothing much to show in the machining, but after turning the .125" section and the reduced .094" section, I used the Sherline compound to machine the angle (photo 1) and the A.R. Warner grooving tool with the .031" insert to machine the groove (photo 2). The end result after the second attempt is shown in the final photo. Thanks to those of you following along.

Jim, it is a great tool for just that kind of operation. Fortunately I was able to extend the head of the valve through the chuck jaws and chuck on the .125" stem so the grooving could be done as close to the chuck as possible. Didn't want to risk bending the stem at this point !!

More progress today finally. I got the intake valve made (again for the second time). Didn't take pictures of the process as it was similar to the exhaust valve but the results are shown in  the first three pictures below.

With that done, I spent the rest of the afternoon finishing up the cylinder head. The valve cages still had to be drilled to .250" from the inside, chamfered and then the valves themselves seated until a good seal is achieved. Photos 4, 5, and 6  show the results of this. For me at leas this can be and usually is a time consuming job so I am glad it is done now and that the head is finally complete.

The last two photos show the assembled head with the valves and springs installed and both seem to be working. I did have to put a small collar under the intake spring. Without it, it wasn't fully closing the intake valve, but with the collar it seems to be working perfectly. Also I was dubious as to whether the leaf spring was going to work on the exhaust valve, but with a little fiddling, it also seems to be doing its job so for now I am going to stay with it instead of the alternate wire spring shown on the plans.

Funny Zee, but I will beat that today by 5+ hours  :atcomputer: 

First up was the small end that will fit in the piston. I fabricated this from two pieces as shown in photo 1. I had previously turned down a length of bronze .219" in diameter, drilled and reamed it to .125" and then parted off two pieces .375: long, one for the small end and one for the crank end (photo 2). With one piece I transferred it to the mill and put the .188 radius on one end to match the .375" diameter of the bearing (photo 3). Then for the bearing part, I drilled the oil hole and 90 degrees around I put a shallow 1/8" hole about half the depth of the bearing wall thickness (where the dowel pic is sticking out in photo 4). I cut a piece of 1/8" OD brass tubing maybe .200" long and inserted this into the hole to align the mounting arm centered on the face of the round bearing piece (photo 5). Holding the two parts together snugly but not tight in a 4" vise grip, I silver soldered the joint (photo 6). This was a perfect size job for the "little torch." After cleaning it up, the final small end bearing is shown in photo 7.

Bill
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on May 01, 2016, 08:28:04 PM
Next up was the main rod piece. Starting from one end, I turned the .125" diameter which will fit into the small end assembly (photo 1). After checking the fit (snug but not a press fit) as shown in photo 2, I set up the compound to .75 degrees and turned the taper with tailstock support as shown in photo 3. The same procedure was then done to the opposite end and the entire length polished up (photo 4). Finally the completed rod is shown with the small end fitted to it (photo 5). Ultimately, both the big end and small end will be silver soldered to the rod.

Dave, the "fixture" barely got warm. The little torch flame was aimed at the fat part of the bearing and as soon as the flux turned liquid, the solder melted and flowed nicely around the joint. At any rate for $2.00 or so a new fixture can be had at Harbor Freight  8).

The lack of comment on mini-mic and the Warner tooling was a test to see who was paying attention and you passed with flying colors  :lolb:  You will note however, mine ain't got no hole in it  :LittleDevil:

Last week of the semester here so no shop time... even had to go in today for the final exam. Next week will be getting all the grades in. Even so I found a few hours this afternoon to continue with the big end bearing. I had left off last time squaring up two small pieces of bronze. So picking up there today I stacked them in the mill vise, drilled a 4-40 tap drill through then opened the other side for a clearance hole as shown in photos 1-3. After screwing the two halves together, I drilled and reamed the 1/4" hole for the crankpin (photo 4). Then it was off to the 4 jaw in the lathe to relieve both sides (sorry, no photo of that). Then back to the mill to reduce the thickness of one half of the bearing (photo 5). Still have to do the other half and then reassemble and finish contouring the area around the shoulder (photo 6), locate the position for the attaching arm and silver solder it, do some finish cleanup work, and finally assemble and silver solder the whole con rod assembly together. Should have time for that tomorrow, maybe even some initial work on the piston.  Thanks for looking in.

Thanks Kim. I did get the con rod finished up today but it took the better part of the day. Some of these parts can take a while to get them like I want...need more hours in the day I suppose.

I started out by finishing up the rounding on the big end bearing using the RT and a 3/32" end mill (Photo 1) followed by a lot of filing with a needle file and the micro mesh sticks to get it looking decent (photos 2 & 3). Then it was a trial fit of all three pieces as shown in photo 4.

IN order to get every thing lined up properly for silver soldering and to get the required C to C distance, I made a simple fixture (photo5) to hold everything in alignment while soldering.  The two pins, sized for the holes in the big end and small end respectively, were drilled and tapped the required center distance. Photo 6 shows the assembly after silver soldering and before cleaning things up. Photo 7 shows the finished con rod assembly and the last photo shows the big end with the crank pin captured between the two halves of the big end bearing.

That's all for today...

Many thanks Don. Not sure why I am fretting over it so much. The little end is hidden in the piston and the big end hidden between the flywheels. I was pleased with how it fit the crank pin though...smooth as silk and no slop whatever. Functionality over looks I suppose, but I was relatively please with the appearance also.

Couple of questions:  Do the short sections of brass shaft fit into pockets milled into the bearing at each end?

                               Were they soldered into the bearings before the steel connecting shaft was soldered?

Post by: b.lindsey on May 09, 2016, 12:14:52 PM
Thanks guys! I appreciate the comments.  Jim, what I did on both ends was to use a short piece of brass pin pressed into the end, which would then locate the "arms" that join to the steel con rod shaft. A radius was also put on the end of each arm to better fit to the ends. I am hoping it will be strong enough since the explosive force of combustion as well as the compression stroke will serve to compress the entire assemble. Any tensile forces should be more minimal.

Yes I used the little torch on all of these with the largest tip....#5 I think. I have rarely if ever used any of the smaller tips.

Both the big end and small end were soldered prior to attaching them to the central part of the con rod. Hope that helps.

Post by: b.lindsey on May 15, 2016, 12:34:32 AM
Today was spent working on the piston and wrist pin. The wrist pin is simply a piece of 3/16 drill rod with a flat on either end (photos 1 & 2). The piston is pretty straightforward but took several set-ups and not quite finished yet, but more on that later. I started with a piece of .875 aluminum and turned it down to about .005" over the final dimension, then cross drilled and reamed for the wrist pin (photo 3). After drilling a 15/64" hole the depth of the cavity for the con rod small end I bored the base of the piston to .725" (photo 4) and chamfered the skirt using the compound (photo 5).

Bill
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on May 15, 2016, 12:44:54 AM
Then it was over to the mill and mounting the chuck on the RT, I lined up the wrist pin hole perpendicular to the y axis and used a 1/4" end mill to mill out the cavity for the con rod in steps(photo 1). Then stepping to the side I drilled the holes (and later tapped them 4-40 for the screws to secure the wrist pin in place (photo 2). The next 2 hours or so were spent getting a scant slip fit of the piston in the cylinder. I turned all but maybe .001- .0015 " and then kept polishing until it fit both ends of the cylinder. Actually this took longer than making the piston but I was happy with the result (photos 3 & 4). The piston slips into the bore of the cylinder but if I close off all the holes and blow in the end of it there is little if any leakage of air. Still remaining is the oil hole in the top of the piston, a v groove just above the wrist pin, and the two grooves for the cast iron rings. I will get that done tomorrow.

Nice update Bill!

Is School out?

My thoughts are that an aluminum piston in an IC engine running rings will need some clearance; I would do at least one to two thou. Can you share your thoughts on creating such a precise fit?

Dave
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on May 15, 2016, 01:27:51 AM
Dave, the plans call for .0005" -.001" clearance. As best as I can measure I have about .0007 now. After making the rings and fitting them I will be able to tell more. What I didn't want to do was to get too much clearance from the get-go. I can always relieve it a bit more if needed, but too much now and the piston has to be remade.

Finished up the piston this morning by putting in the oil hole and the v groove and the two ring grooves. Not sure if I have enough CI stock for the rings so may have to order some. All I have is a couple of very short lengths of 1.5" CI but can maybe squeeze the two rings out of it. A couple of pictures of the piston and con rod are show in photos 1 & 2.

I realized I hadn't made the off side pulley either so I got that done before the gremlins found that piece of brass and made off with it :) I did everything I could in one chucking...facing to final width, drilling and reaming the center hole, putting the relief in the first side and then cutting the 3 degree face angle (photo 3). With that done I was able to turn it around and chuck on the inside of the finished side, to add the relief and the face angle to the other side (photo 4). The plans call for drilling straight down through the rim of the pulley and then into the hub and center bore but that leaves a hole in the rim which I prefer not to do. Instead I angled the pulley in the mill vise and was able to drill and tap an angled hole instead for a 4-40 set screw (photo 5). Photo 6 shows the pulley in the approximate position where it will be once completed.

Is the V groove in the piston intended as some form of oil control?
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on May 16, 2016, 02:03:04 AM
Roger, I assume it is to spread the oil coming from the drip oiler up into the cylinder since it passes right under it on each stroke.

Bill

Well the afternoon was just as productive as the morning. It turned out I had enough CI on hand though it was a bit large at 1.5" diameter. Before the description starts on the rings, keep in mind the end goal was two rings .850' diameter with a .032" wall thickness. The plans call for .047 wide rings but since my Warner grooving tool doesn't come with a .047" insert I opted to make them .062" wide instead.

The scrap piece of CI was turned to an OD of about .870" and an ID of around .765". These dimensions are critical so long as they give room for later machining as will be shown. The result is shown in photo 1. There was enough stock to part off 5 rings of about .070" thickness which ended up being a good thing :) (see photos 2 & 3). My first though to split them was to make a diagonal score mark with a triangular needle file and then to grab either side of the score with pliers and break it (photo 4). This unfortunately didn't work so instead I cut through them with a dremel cut-off wheel also on the diagonal. I was down to just two remaining viable rings at this point so it was looking like more of a practice run. Making additional raw rings wouldn't be that big a deal anyway. The next step was to make the two fixtures needed for the next steps.

The first (photo 5) is to clamp the raw ring so that the gap is closed and so that its OD can be turned to the .850" required for the cylinder as shown in photos 6 & 7.

More to come but too may pictures for one post.

Bill
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on May 16, 2016, 03:07:16 AM
Then it was on to the second simple fixture. The purpose of this one is to hold the ring by the OD in order to turn the ID until the desired wall thickness is achieved. This is shown in the first picture. Given the small size of these rings, only the natural spring of the rings keeps it help in the fixture,  so the raw ring ID was chosen so that only a few thousandths would need to be removed from the ID and this is done in very small steps of half a thousandth or so. Believe it or not with a little patience this does actually work and results in a truly round ring without the need for any heat treatment.

Photo 2 shows the final wall thickness with the ring sprung open slightly. That leaves the width of the rings still to be finalized to the .062" needed in this case. That was done by working both sides of the ring in a circular motion on some 220 grit paper (photo 3) until the dimension is achieve all around the perimeter of the ring (photo 4). The last photo shows both rings installed on the piston.

Once this was done the piston was inserted into the cylinder, slightly compressing the rings as needed. At this point for me at least it is a matter of feel as to how things are fitting. It should take a little finger pressure to move the piston back and forth in the cylinder and obviously feeling more friction than the raw piston alone. Given that the rings will run in over time I want to feel a moderate amount of friction though its hard to put into words, as noted its more a matter of feel. So what I though was going to turn out to be a trial run, ended up with the rings done and I am  more than happy with the fit as it stands now.

That's a small micrometer you've got there  :)  :)  :stir:

There is a theory that piston rings should be thicker on the non-gap side to give an even pressure all round but I'm not sure it is really relevant in these sizes. I have just given my rings a final skim after heat treating.
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: zeeprogrammer on May 16, 2016, 01:27:04 PM
Nicely done Bill.

I first read your posts at home this morning and was confused as to how you turned the rings after making the gap.
Now at work I reread and see. Very good.
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: zeeprogrammer on May 16, 2016, 06:03:11 PM
Still pondering this.

Why did you cut the break and then turn to size?
Why wouldn't you have turned to size and then make the break?

I'm guessing the OD changes because of the break? Wouldn't the ID as well?
 :thinking:

I'm not pointing anything out. I just don't know.
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on May 16, 2016, 06:55:07 PM
Zee....here is the reasoning. When making the break as I ended up doing with the dremel cut-off wheel, the gap will be larger than working gap for most rings. In the case of the P & W the gap is sipposed to be .002" though I am sure mine is probably closer to .005". The ring will also spring open a bit once cut. Using fixture #1 the ring is squeezed until the gap is almost closed and then clamped with the outer part of the fixture so it won't open back up during machining. Remember the raw ring is made oversized on the OD and smaller on the ID before any of this is done. This fixture #1 then gives you a "round" OD the exact size of the cylinder ID. Of course once you take it out of the fixture it springs back open again a bit. Thus the opening of fixture #2 is made to this same cylinder dimension...in my case .850". The ring is then squeezed closed again until its OD fits in the fixture which leaves the ring ID open for machining. There is no good way to hold the ring in this second fixture other than its natural springiness...though I suspect Stan's crystal bond glue stuff might could be used to do that. At any rate, as long as you take teeny cuts the ring will usually stay put. Also as long as fixture #2 is true with the axis of the lathe, the ring ID will be concentric with the ring OD and in the compressed state both will be truly round. When the finished ring is removed from fixture #2, it still has the original springiness which is ultimately what presses it against the bore of the cylinder.

This is not my original technique, but was taught to me by Doug Kelley (snow engine) who still uses it for all his rings. I did it this way on the Briggs as well and its still going strong.  Hope this helps explain it better. If not let me know and I will try again.

Post by: b.lindsey on May 17, 2016, 03:45:25 PM
Thanks guys. For our purposes as modelers with low run time hours on most of our engines, I think that leaving the rings in the natural unhardened state is sufficient, and keeps me at least away from the black art of heat treating and then tempering properly so the rings can still be fitting over the piston without breaking due to brittleness. Would be different perhaps if I had a nice heat treat oven! In the case at hand, both of the rings I got to the completed point fit over the piston and snapped back into the ring grooves without incident and seem to be exerting enough pressure against the cylinder wall to seal properly, though proof of that remains to be seen of course.  Being down here in the heart of NASCAR country, it would be a different thing if the rings were for an 8000+ rpm racecar engine, but that is a whole different world...some amazing engineering to be sure, but well beyond my capabilities.

My point exactly Cletus, though for anyone interested, the next two weekends will be full of activities here at the Charlotte Motor Speedway. Probably a few blown engines along the way too. As a side note, one of the salesmen for the Haas Machine Tool distributor in Greensboro moonlights as an announcer for some of the races. Super nice guy, he has been doing it for years. Occasionally, if I had some business with him, like when I bought the two CNC machines for the school, and happened to forget it was race week, he would still call me back if only to say he was at the track and would get back to me ASAP. While I am not a race fan, I did have occasion to visit the speedway once for a tourism event and got to tour the "garage." Actually dinner was being served there and while they didn't make us, you could have eaten off the floors....they were that clean.

I had previously made the pin that the brass handle fits over and spins on but didn't take any pictures of that. The business end of the crank handle, the part that engages the pins on the gear shaft was cut to length, drilled out to .187" then cross drilled .052" The pins are .047". Then I set the angle on the mill vise and used a small burr to finish the angled slots as shown in photo 1. Photos 2, 3, and 4 show this part as it engages the pins on the gear shaft. Sadly, I should have measured before making this part, since it was not long enough to allow the finished crank to clear the wood base the engine is mounted on...so a second one was made .500" longer. Thankfully I discovered this before silver soldering it to the body of the crank.

The main body of the crank is made from .375" x .188" mild steel. All I had on hand was some .500" x .250" so after some flycutting and milling I ended up with the blank shown in photo 5. I did make a mistake by drilling our the smaller end (where the brass knob attaches) to .188" rather than the .136" of the pin diameter, but a small bushing fixed that. After some bending, silver soldering, and a LOT of clean up the finished crank is shown in photo 6, and then shown in place in photos 7 & 8. The little torch was again used for this silver soldering and worked well even given the thicker mild steel body of the crank.

Hey Bill,
Looking at your crank, scratching my head, and then comparing it to mine, I'm finding out that the 3" dimension shown on the drawing should be 2".  (A scaling error in the dimension.)
Your's should work fine; however, I'm a little worried about the moment arm on the extra long pawl on the small crankshaft.

My apologies for the error.
Todd.

Post by: b.lindsey on May 23, 2016, 12:40:55 PM
Thanks for the info Todd. Disappointing to say the least, but nothing to do but remake the steel part. I looked at the one I made and the locations of the curves just don't allow for shortening it. On the plus side the brass part and likely the pawl can be reused, and the steel part will only require 2/3rds the machining  ;D.

On a separate note, when I do drawings in AutoCAD LT, the only thing that scales in the dimensions is the font size of the actual dimension number, not it's value. Meaning that if I know I am going to print a particular layout at 2X scale I will set up a separate dimension style to be used only with those layouts. For example the height of the dimensions will be half that used for a layout to be printed full scale, so that when the 2X layout is printed the size of the dimensions doubles but the values remain the same. That way when looking at a full scale sheet and a 2X sheet side by side the dimensions appear to be the same size. On the other hand I rarely if ever use associative dimensions which might act quite differently. Anyway, something you might want to look into to avoid these scaling errors.

Bill

Title: Re: Parsell & Weed Horizontal IC Engine
Post by: littlelocos on May 23, 2016, 05:50:13 PM
Hello Bill,
Associative dimensions are a must for my projects.  In TurboCAD there are several variables that can set the dimension scale.  The first sets the overall scale of how the dimension is drawn (like you describe).  The other sets the units of the dimension to whatever the user decides.  In this case, all other dimensions on the sheet were set to 0.6667 to correctly dimension the details.  The 3" dimension was set to a unit scale of 1.000.  You would think that something as simple as matching the scale of the dimension to the scale of the object being dimensioned would be automatic.

What you describe is my understanding of the AutoCAD way and is the same as I was using in AutoCAD waaaay back in 1988-1991 drafting my way through college.  This is still done when the text resides in model space.  When the text and dimensions reside in paper space (as I do), dimension scaling is easier, but unit scaling is more difficult.

It's also surprising how long some of these errors persist.  I recently had a builder of our little Puck flat head engine point out the same issue with an entire section -- on a 10-year old set with 100+ copies on the street.

Again, my apologies for the error,
Todd.

Thanks Bill,
You may notice that the crank I made for Woody's engine is a little fancier in that the hub for the crank handle is rounded.  I simplified that for the final design as it was a pain to make it that way.  I do like the way it looks though.

Post by: b.lindsey on May 24, 2016, 12:16:58 AM
Todd, I have the new steel part almost finished...its all tapered, rounded on both ends and drilled for the pawl and handle pin. I will sand it smooth tomorrow evening and hopefully get it bent and silver soldered together as well.  Then its just all the finishing sanding to do to make it a smooth as the one made previously. I will reuse the brass handle and if I de-solder the longer pawl I should be able to cut it off and use it on the new one as well. As with most things, it went faster the second time around.

The new improved crank handle is now finished!!  The old one (1" too long) is shown in photo 1. The new one is shown in photo 2 from approximately the same viewpoint. You can see that it clears the wood base now and allows for the pawl to be shorter as well which was Todd's concern and I tended to agree with him. Photo 3 shows the new steel body after bending. Once the steel is heated to a dull red it actually bent pretty easily. Photo 4 shows the new crank handle from a different view and the last photo is of the old steel part alongside the new finished crank assembly.  Looks better don't you think Todd? Sorry about the slight detour but we're back on track now and happier that this part is now correct.

Post by: b.lindsey on May 25, 2016, 02:21:08 AM
Don, I guess it will depend on how easy the engine starts. A couple of turns wont be too bad. Much more than that and you might be right. But I have a back up plan in that case...a pawl attached to a drill :). Or possibly just turning the flywheels over as well if it starts easily. Even so I still wanted to make the crank handle, just hadn't planned on making it twice  :ShakeHead: Got some good practice with finishing techniques though.

Bill
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: littlelocos on May 25, 2016, 02:35:40 AM
Bill,
I think you'll be pleasantly surprised on cranking the engine.  The handle is about like a nice fishing reel.  At 4:1, the compression isn't so high as to make it hard to crank over.  At 6:1, as originally designed, it was a bear to crank and didn't have enough momentum in the flywheels to carry it over to the next cycle.

Here's what that looks like:  0LT_Te66_cw
A whole different animal at 4:1.  oJ_aC_2xaCE
Enjoy!

Hello Bill,
I used points as shown on the drawings.  This seems to work well.  My understanding is that Woody uses a buzz coil with the points on his.  I like the ignition modules from S/S.  A hand cream "tin" worked great for the prototype.  I may eventually build a nice oak box around one.

Hi all, after a 2 month hiatus on the P&W, I am pressing on now. It has been too hot to do too much out in the garage but have managed to get a few things done while working on the flywheels at work.

While the gas tank/cooling tower was completed a while back, I had yet to add it to the base so I got that located and done this morning (photo 1).

Have also been giving some thought as to how to finish the model once running and am leaning towards a medium brown (chocolate) color as shown in photo 2. Likely not prototypical at all but I think it will work nicely with the brass and bronze surfaces and fit well with the wooden skids also. This is not finalized yet, but I am liking it the more I look at it.

This afternoon I will get the two tubes cut and threaded and soldered into the water jacket. More on that later.

A question for Todd.  I am thinking as to connecting the water jacket piping to the cooling tower, and have ordered and received the necessary fittings (ells) and brass tubing from PMR.  I also ordered two 3/16-40 unions as I was thinking about using those rather than a short length of silicon or pvc tubing for the final connection. I realize that the length of the tubing would need to be very close since both the tower and engine base are hard mounted to the wooden platform. Is there a reason I should NOT give this a try and just go with flexible tubing?  I think the all metal tubing with the unions would look better but not if at the expense of function. Any thoughts?

Bill
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: littlelocos on August 07, 2016, 05:19:10 PM
Hello Bill,
Hard-piping is fine.  I prefer that myself as it looks better.  As long as you've got a pair of unions in there you should have no problem.  The plastic or rubber tubing is easier to pipe up as it adds a little more flexibility.  :-)  At this scale expansion due to heat is negligible.

Todd.

This afternoon I modified the coolant outlets on the cooling/fuel tower, in order to add threads for hard piping unions. Photo 1 below shows the way it was with just plain 3/16" OD tubes sticking out. Photos 2 & 3 show the modified arrangement with the unions temporarily installed.  I did have to de-solder the old tubes and replaced them with two new ones already threaded on the union end.

Post by: b.lindsey on August 08, 2016, 12:50:55 AM
Thanks Jim, it will be a little tricky getting the height of the vertical tubes coming from the water jacket just the right height so that the horizontal tubes are both level and parallel to each other, but doable I am sure. Also getting the lengths just right as well. But I agree it will look much better than flexible tubing.

Oh by the way, you had asked about solder on another thread as I recall. I used the PMR solder in this application and it worked perfectly.

Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on August 08, 2016, 02:11:50 AM
Pete, on the horizontal pieces, the threads themselves can make for some adjustment.  For the vertical tubes, the ells will have to end up facing the tower, so I can adjust the height .025" per revolotion based on 3/16-40 threads but since the tubes also thread into the water jacket, I should be able to get even finer adjustment as needed. Once I an happy with it the vertical tubes will be soldered as well as threaded into the water jacket collar.

Plan B on the flywheels. The lathes at work, need some fine tuning and tightening of gibs, etc. which I haven't had the time to do. So another route. Today I ordered the riser blocks for the lathe head and the tailstock, and the tailstock extender which has been on the want list for a while. This will allow the flywheels to be done here. Part of the decision is that the next project will require them as well. So stay tuned. This weekend I will finish up the piping instead.

The piping is now done. Photo 1 shows a close up of the upper union. Photo 2 shows the upper piping complete but not het soldered. Photos 3 & 4 are after everything was done. All the threaded joints were soldered to prevent any leaking. After doing the soldering I did find one small leak on the underside where it went into the water jacket so I resoldered that and tested again and all was good. The only way it will come apart now is to de-couple the unions and take the water tower off the base, but that shouldn't be needed. All in all it looks good I think and as level and parallel as I can get it.

When polishing the brass, do you guys end with a coating to prevent tarnish, like a lacquer or something?
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on August 14, 2016, 02:32:48 AM
Don, not sure if I will ever get my brass as shiny as yours. Chris...I will let Don answer your question, but I don't put anything on mine. The Maas polish helps I think by leaving behind a protective layer.

Don, the little sander thingy saved my butt today. Paid for itself in one use. While soldering the lower union where it threads into the tank, I let the little torch get a little errant in its direction and the end of the flame singed the top of the wood cross piece in the area shown in the photo below.  Once I took the tank off I used it to sand this area back down to bare wood, then restained it. I still need to add a coat of urethane on top of it but it got it back to wood color rather than an unsightly dark singed look.

Like Bill said I use Maas and it does leave a small protective coat but I don't lacquer my engines because of the moving parts. They stay in doll case with the top completely sealed. The only air that exchanges is through thermal expansion so less humidity. They get a nice patina on them and don't change after that. I polish them when I feel like it.'
Bill glad the sander works for you buddy. The more you use it the more you will find it's uses. If you haven't tried it on brass you need to. It helps remove some of those deep scratches in you work also great on steel marks..... :popcorn:

The last time I polished brass was in the service, Brasso was the answer put it on let it dry and then wipe it off and that would leave a nice shine, occaissionally we would use hairspray to seal it, but I have no idea how it would handle the heat, on the other hand another coat of brasso would polish it up again.

Post by: b.lindsey on August 16, 2016, 07:47:11 PM
Hi trackwelder, and welcome to MEM. I have certainly heard of modelers using shellac or other clear coatings over cleaned brass, but there is also the risk that if any moisture or other contaminant gets sealed in under the coating, it can still cause tarnish or discoloration in localized areas and then you have to remove the coating as well to clean it up again. I am more like Don in that regard, just repolish as needed before a show or whenever you wish to for that matter.

Not to repeat what he said, but yes please do take the time to post an introduction in the "introduce yourself" section. That was more can say hello and welcome you than may be just following this thread. Thanks for looking in to.

Photo 1 is the headstock riser, photo 2 the tailstock riser, photo 3 the tailstock extender (this one will come in handy often I suspect), and photo 4 the higher toolpost which is supplied with the headstock riser block.

Ready for the next big flywheel!   :cartwheel:

I have the riser blocks for my Sherline too, think that I use the headstock riser more often on the mill to give more horizontal reach than on the lathe, but comes in handy on both. The tailstock extender is most handy for getting the live center to reach in farther, especially when the QCTP is angled for some cuts. I don't use it much for the drill chuck. 
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on August 22, 2016, 12:31:58 AM
Got a bit done on one of the flywheels this afternoon, though in spurts, it was still HOT in the garage today. A couple of pictures are shown below. Height was not a problem with the riser block, but as I knew already, working that much farther out from the centerline of the lathe does put more strain on the motor. Rigidity seemed ok once I got past the interrupted cuts on the periphery of the flywheel from the casting gates, etc. I played around with several toolbits...the Warner insert bits, a 1/4" ground HSS toolbit, brazed carbide, and the tangential.  Actually the tangential seemed to work the best and is easy to keep sharp which is critical. This will work but not fast. Even so it will go fster than trying to get it done at work the way things have been lately. In the pictures, I just about have the OD of the flywheel down to the 5" specified. Now working on getting the thickness faced down on one side and then will do the other side. More to come over the days ahead.

Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on August 22, 2016, 12:51:37 AM
Kim, the riser blocks themselves are plenty rigid given the capabilities of the machine. The taller toolpost is the only place  I see less rigidity since is it about 1.25" higher off the crossslide then the normal height set up with the QCTP. This was particularly evident working on the rim of the flywheel with the interrupted cuts as noted earlier. This set-up certainly adds versatility, but at the expense of torque and toolpost rigidity for larger diameter parts. I am confident I can git 'er done though with a little more experimentation.

The tailstock extender I am very happy with, wish I had bought that years ago!!

Bill

Looking good so far Bill. I've been shying away from any project that had a flywheel larger than 3", but will be looking beyond that now.  :whoohoo:

Did you have to go to the lower speed pulley setup?

I'm going to emulate the setup you have for the flywheel and figure out if I need the Tailstock Spindle Extender with my Tailstock that has the cut-away.

Jim
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on August 22, 2016, 11:54:53 AM
Jim, I had upgraded my tailstock several years back with the newer version that has the cutout. I still find numerous circumstances where the extender will be useful, particularly when the toolpost is in the cross slide t-slot closest to the lathe head, which mine almost always is.  You can determine that for yourself but I suspect you will eventually come to the same conclusion.

The flywheel is coming along nicely, Bill. Always a challenge to work at the limits of your machines size capability. I've had good luck finishing the lion's share of the spokes with one of those teeny belt sanders. Although with the size, it may not accomplish much. Shouldn't be long now.... Paul

Bill,
I'm looking forward to more progress reports when you get there.

In the meantime a request: Dealing with setting up a casting for working on it (lathe or mill) still seems like a bit of a "black art" for me. When you have a time, could you elaborate on just how you mounted the casting in the lathe accurately and got it turned to the point where it is in the first picture?

Also: Did you have to change the motor belt to the lower speed position for turning?

Second "Also": What is a tangential" toolbit?

I've sure been learning a lot from this build thread.

Thanks, Jim
Title: Re: Parsell & Weed Horizontal IC Engine
Post by: b.lindsey on August 24, 2016, 03:49:40 PM
Jim, In this case I am chucking on the center hub of the flywheel...not the most rigid option but the only one available given the geometry of the flywheel casting. I did center drill the outer end and am using a live center to add some stability. I will see how this goes and modify if needed. I did not try changing the motor belt but may give that a try to boost torque. As to the toolbit, I should have said tangential toolHOLDER rather than toolBIT. They are also known as diamond tool holders. There are a few threads on here about making your own in fact. Mine was bought years ago from bay-com enterprises, but I was surprised to learn that they apparently no longer make the one utilizing 1/8" square toolbits and now start at 1/4" instead, likely a bit large for the Sherline. I will try to get some better pictures here tonight if I can.

Jim, I,  like you,  was leary of castings at the beginning.  It did seem like a "black art ", and me being a non conformist,  only led me deeper.  I have determined they are much like women : each is different,  each must be held and treated differently,  however,  when and if,  you figure out where and how to hold them ; they are well worth the trouble.  Just a redneck POV.  Now being a true redneck,  can't let any of this wane your desires,  pick you one and give her a whirl  :lolb: :lolb:

Much more eloquently said than me Cletus, darned fine analogy too!!  Jim, some of the PMR casting kits are great to start out on, like the small oscillator or the small horizontal mill engine. And if you do happen to mess up a casting they are also great folks to work with as far as getting a replacement.

Thanks for the analogy Cletus..........I like that! :naughty:

I think it was Jo that said that the part you need is buried inside of a casting. The trick is to cut it out in such a way that the whole part is contained where there's metal.............................or something like that!  :Lol:

Bill, it's interesting that you mentioned PMR casting kits. I actually have this one: http://www.pmmodelengines.com/shop/steam/steam-engine-2/ The nice thing is that I was also able to buy a companion DVD where a fellow shows how he built it....................using a Sherline Lathe and Mill no less!  :whoohoo: I've watched about 1/2 of it now and think it's going to help a lot.

Hello Bill and Jim,
Bronze is more expensive than aluminum, but for an engine that small it still should be do-able.  We use bronze because I like it and have designed the foundry patterns to economize on the number of pours and on casting weights.  So far, we plan to stick with it, but might offer an aluminum base option on our next engine to keep some of the costs down for the beginners we're working to on that one.

Glad to see the flywheels turning Bill!  Keep up the good work!  :-)

Finally at long last, a little shop time. Work has continued on the first flywheel and with the exceptions of cleaning up some of the flash on the casting, narrowing the width of the hubs, and drilling for the crankpin hole, this one is just about finished. I will be the first to say that doing this on the sherline with the riser block setup is far less than optimal. Doable yes, optimal no. But I will press on. I am attaching a couple of pictures just to prove that some progress has indeed been made :)

It IS nice to have a lathe/mill that will fit in the house without major structural support or riggers to bring in, will fit through doors, and will fit on a benchtop that you can pull a chair up to!

It's great to see you back at this project Bill.  :ThumbsUp:

I'm also pleased that you're persevering with doing the flywheels on your Sherline lathe. I'm watching this process closely.

Hello Bill!
Glad to see you back at it.  I stopped by today to check progress and maybe send you a note to see how you're doing.  Delighted to see the progress.   :pinkelephant:

If it's any encouragement, when times get busy, stopping for an hour even if only to work on one surface of one part is still moving forward (and taking a much-needed break). 

Keep up the great work.  LMK if I can be of any assistance.

Enjoy!
Todd.

I was never happy with the mounting hardware for the cylinder and crankshaft supports. Then 4-40 hex head screws are somewhat of a pain to put in as well. Anyway, I had ordered some 4-4- studs and a length of 3/16" hex stock from McMaster and got the nuts made. I think it looks a bit better and so far seems easier to put them on and take them off which will be needed for final painting, assy., etc.

Wow, over two years since I last updated, but a productive hiatus none the less with retirement, shop revovation, and new house taking up a lot of time. But it now time to make some swarf 1again and get this one finished up.

One of the main issues was machining the flywheels. I tried this on the sherline with risers, but was never pleased with the results. Photo 1 shows some of the chatter due to lack of rigidity. Not an issue in the larger lathe, now back in service (photo 2), with much better results (photo 3). So this is where things stand currently (photo 4), pretty much everything is done except finishing this flywheel and doing the second one, then a disassembly and good clean-up, painting, reassembly,and seeing if I can make it run. Nice to be making chips again and I promise updates will be forthcoming more rapidly.

Hello Bill,

That must make you feel good to turn something in that lathe that has so many memories. Good to see the chips again.

Have a great day,

Yes the Little Pearl is waiting to, but these two are nearly done. The Pearle has a ways to go yet and want to be able to concentrate on it by itself.

Thanks Kim!! The spring weather has been a boost too, though believe it or not we actually had some snow yesterday. Only lasted an hour or so and didn't stick at all...too warm for that.

Well I was. Shop time has been limited lately, trying to get moved to the new place. Should resume shortly though.
