Title: Newbie building a PMR 6CI
Post by: vdubjunkie on April 23, 2018, 04:18:01 AM
Hello all,

I found this site while desperately searching for the existence of a Corliss kit, believing they are not produced by anybody in the states at this point.  I'm still not sure there are any kits, and I don't really have capacity to start one, but better yet, I found this site.

After finding the MEM plans and following the build pages for two members here, not only was I excited about the prospect of doing this myself one day, but I was also inspired to post a build page of my own.

My engine is nothing fancy, and it's not likely to wow anybody with my amazing skills.  I am new to machine shop, and it is my first project.  My shop is VERY modest, and it has taken me a couple of years just to build my tooling to a mostly usable shop.

I'm certain there will be a number of people from this site I would add to my list, but for now, I'd just like to thank some #Invalid YouTube Link# folks who have made a significant impact on my learning curve.

Keith Appleton
THATLAZYMACHINIST aka Marc L'Ecuyer
Clickspring


Also, in person, I received some fantastic help from Bill Wing.  There have been a number of other resources I appreciate for various reasons, but here is where I've learned a bulk of what I've used to progress my own craft.  It is amazing to me the effort people will put out to help others in this way, and I cannot say enough about how I feel toward these people.

I could go on, but instead, let's get into my project.  I chose the PMR 6CI engine because I found a detailed build log on a website, and often the best way for me to get into something is to basically "copy" what somebody else has done.
There will be, and have been some differences not only with how I accomplish certain work, but in the final product.  However, I like how he did nearly everything.
So, here is that build page, and a huge thanks to RC Don! 
http://rcdon.com/html/6ci_steam_engine_project.html (http://rcdon.com/html/6ci_steam_engine_project.html)

He also did a great job putting together his own boiler, and I hope to do the same at some point.

For those who can use help visualizing the finished product, here is the image on the PM Model Engines website.

The oldest pictures I have are dated 2/23/2016.  This is effectively when my project began. 


How exciting is it opening and inventorying your first casting kit?

Here I am practicing setting center height, and putting my carbide tooling to use.  Later I decided to focus on HSS for a variety of reasons

The only critical measurement on the flywheel being the bore, it was a good choice for the first part machined.

It's time to start making my own tools.  That didn't take long.  This was my first week, come to an end.

Is the only way to do better images to have them hosted externally?  Maybe somebody can offer some advice.

 :hi:

Looks like you are off to a good start on that model engine and started with a very nice looking set of castings  8)

Would you like to put a separate introduction post about yourself in the introduction area so the members can get to know you :)

Great to see a new member and new build log at the same time, so thanks for jumping right in!!  The 6CI is quite a large engine and as I recall there have been a couple of #5's build here on the forum as well. Best wishes as you move alone on your project and just holler for help if you get stuck anywhere along the way. That is partly what the forum is about.

I've posted a bit about myself.  Thanks for helping out with that.  As usual, I go for the meat, and there's no telling how long it would have taken me to find the introduction section.

So, these next couple of pictures were from the week of 3/6/2016.  I wasn't able to do anything the week in between.  This Sunday, I had returned from a Scout climbing and rappelling event we do each year, and got right to work.  However, I only had pictures from two days this week.

The weekend of 3/19 & 3/20 I tried my hand at using a reamer with very good results.  I've seen several people use the same method to cut a keyway inside a bore, and again I was very pleased with the result.  I knew it would be important to get the width of my cutting tool just right, and spent a fair amount of time considering how the metal should taper away from the cutting surface.

If anybody isn't familiar, I locked the flywheel in the headstock and used my cross slide to slowly scrape away layer by layer.  I took my time ensuring the tool was positioned properly, and at the correct height.

My calipers confirmed that the keyway was precisely the right width.

Between 3/29 and 3/30, I was able to move on to a crank disk.  Being VERY new to all of this, I spent a great deal of time ensuring that it was aligned and centered to the best of my ability.

Can I just say how much I love watching a part progress through being turned?  I started off with a center drill, then moved on to a smaller drill.  Next, I was able to move on to a drill just under my final dimension.  Here, I was supposed to be shooting for about .0015 to .002 under .625 so that I could press fit a wonderfully perfect 5/8" rod into the hole.

Unfortunately, this is not what happened.  This being the first time I had attempted such precision, I failed, and the hole wound up a perfect slip fit for the 5/8" rod.

What a valuable lesson to learn so early.  Turning appropriate rod for this would later become a pretty challenging process, with lots more lessons to be learned!

Drills are primarily bulk material removal tools.  They drill holes that are neither round, straight or on-size.  Drill undersize to remove the bulk of material then, if necessary, bore to make the hole round and straight.  Follow with a reamer to bring the hole to size.

For jobs like this you may want to simplify your life by obtaining a set of over/under reamers for aliquot sizes, e.g...

https://www.amazon.com/14pc-Chucking-Reamers-Under-Sizes/dp/B01N0XXBA4/ref=sr_1_2?ie=UTF8&qid=1524502822&sr=8-2&keywords=over+under+reamer+set

That's a great point.  A set of over/unders is a very good idea.  I knew about drills being very inaccurate, but I hadn't previously seen the idea of boring between a drill and reamer.  Of course, at this point I'm primarily buying my tooling one at a time.  A big exception was my set of collets for my milling machine.

Between 4/5 & 4/9, I did two things.  If you'll notice the picture of two crank disks, look closely.  There is a void in the otherwise lovely surface on one of them.  I was unable to get past the void before going past dimension.  PMR was great about this issue, and simply sent me a replacement.

I know I'm going to come across like a broken record on this point, but I just don't seem to get over how fun it is to watch a part slowly go from rough and nasty to smooth and pretty.  For me, it's a bit like watching fire.  It's almost therapeutic.  The methodical elimination of more and more sections of rough surface never fails to hold my fascination.  Am I alone here?   :shrug:

You may have noticed a bit of a grinding gouge which remained prevalent throughout a majority of the turning of the outside of the flywheel.  Now it begins to disappear and my joy is inversely related to the elimination of its presence.

7/10 brought me what I'm willing to consider completion of the turning on my flywheel.  There's still more to be done before it will look nice enough, but nothing that will be done on the lathe.

7/23 afforded me some clean up and this ugly effort.  Not having a large enough machine to handle this properly, I decided I could get it close enough without using precision instruments.  Ultimately, it was a sacrifice I felt I had to accept.  Again, here was a learning opportunity.  At least it shouldn't affect the overall operation when it all comes together.

Looks like pretty good progress!  :ThumbsUp:

I know I'm going to come across like a broken record on this point, but I just don't seem to get over how fun it is to watch a part slowly go from rough and nasty to smooth and pretty.  For me, it's a bit like watching fire.  It's almost therapeutic.  The methodical elimination of more and more sections of rough surface never fails to hold my fascination.  Am I alone here?   :shrug:

Nope.  ;D

Thanks for the encouragement gentlemen.  I think maybe it tends to work this way.  After a big "break" for working on my project, I tend to get more work done in a shorter amount of time afterward.

The week of 7/31/16 was this way for me.  I was able to complete my inboard head and get the second crank disk complete.

I enjoy the feel, sound, smell and appearance of turning cast iron.

Isn't that just beautiful?  I've seen people discussing how they felt like a casting was cheating until they worked with it.  This sort of opened my eyes to the idea that you can make complex parts from blocks of steel.  However, even if I thought it was a bigger accomplishment to create from a block, I would always want to continue using cast iron too.

The one thing I don't care for is that initial layer of sand.  I'm certain I have room to grow with experience of tearing through this initial layer.  Many, if not all of my cast pieces were turned with the carbide tips I purchased as part of a kit of tooling for my lathe.  I've since moved on to nothing but HSS.  I'm enjoying that very much.

Not all of my efforts at precision came together well, but I've generally been able to "make it work" anyway.  This is an example of a successful part due to efforts at precision.

I know I should be over this, but I'm just not.  I did this two years ago and I still get excited when I see it.  I'm fighting the urge to begin a new project.  Fortunately my lack of funds makes it much easier.

You may have noticed that I began by using black marker until I felt I could pony up the $$ for Dykem.  It worked fine, but Dykem is definitely more visible.  I've also still not put any real effort into lighting.  I have a cheap aluminum flare housing for a bulb clamped up high over my lathe, and I often employ a camping headlamp.  One day I'll get some real lighting for the shop.

Remember how I said chunks of time go by sometimes?  Well, we're now picking back up on 1/1/17.  At one point, I picked up this lovely 1946 Burke Army milling machine.  It's a 3 phase motor, and I had to wait for some Christmas money to get the VFD so I could spin it on a 220V breaker.

I also met a real machinist who practically laughed at my little machine.  I didn't take offense.  He also hooked me up with quite a few horizontal machine cutters.  I've learned that most people don't bother with horizontal machines anymore.  I also got a very pleasant surprise when I bought the machine.  After we agreed on the price, we all learned together that it had a vertical attachment.  I use the vertical attachment probably 85% of the time.

This would become one of my crank rods.  As much as I hate to admit it, the whole reason I had to turn these is because I failed to sneak up on a press fit diameter on the crank disks so that I could simply use 5/8" CRS.  Worse yet, I then failed to sneak up on the diameter of the crank rods, and later I will have rebuilt these!    >:( :(

Looks like it is coming along nicely. That mill is a beauty - what a find!

I now work in a decent size manufacturing concern, with a lot of machinists. Machinists do tend to snicker at our little home machining projects, but they have a very different set of goals to the home model maker. I've found the guys at my place to actually be genuinely interested in what I do at home on these projects. They have a bit of a giggle too but it's all good, they are a wealth of knowledge when it comes to needing help on fixturing and set ups. They seem to be somewhat impressed - or pleased - something positive anyway - that one of the design engineers actually has a try at some "real work".

Anyway - off topic a bit there. Nice looking engine, I shall follow along with interest.

Time can get away from us can't it? Happens to me a lot. It's been over 2 years since I worked on a model engine, but I'm coming back to it at last. But that's another story.

There is probable a need for greater skill, setting up and using to a high standard on a small hobby mill than a large industrial one.

Thanks for the encouragement guys.  I would definitely agree with you about "real machinists."  This guy I know snickered a bit about my machine, but he is really nice and very helpful.  At one point I realized he was taking time to answer my simple questions when he needed to be focused on a deadline, so I've given him a break from me.  I need to call him soon.

While the project hasn't turned out perfectly, I still think he'll be impressed.  When he heard I was doing this project as my first step into machining, he was skeptical for sure.

I'm trying to "bang out" some of these posts so I can get you all caught up with where I am now.  I have quite a bit of the parts made, or very close at this point.  There is a need to purchase more stuff again, so we'll just see how it all plays out.

Happy freakin' Birthday to me!  1/22/17 I returned home from a "Polar Bear Campout" with our Boy Scout Troop.  If memory serves, it was about 50 degrees, so we didn't exactly earn a Polar Bear patch.

However, this week was very eventful for my project.  First, I began by shaving down my pillow blocks.  I really enjoy the action of my simple little machine.

Same deal on my cylinder.  At the time of this writing, my cylinder is complete with tapped holes, etc and I actually just finished the valve today, so it's crazy seeing this early stage.  Sometimes I take for granted just how much I have already achieved.

The week of 1/29/17 saw some decent progress too.  Before I was able to save up enough money to get a set of collets, I used this old drill press.  This is NOT a recipe for precision, but I've often done what I felt necessary when I felt the risk to reward ratio was reasonable.

Since my lathe is VERY basic, I found it helpful to manually add a gauge to my saddle travel to assist in obtaining the precision needed while trimming down the length of the cylinder.  The only issue with this method is that I have to be VERY careful not to bump the magnetic base.  Yes, I learned this from experience multiple times.   :zap:

Look at that finish!  I know..  broken record.  Anyway, you can see the less than perfect nature of the holes for the piston and valve.  We'll take care of that later.

Within this same week, I was also able to begin spinning my cross head.  I had already learned how carbide tips don't appreciate interrupted cuts.  I'm using a homemade boring bar with a small piece of HSS.  Later I will learn that the design sucks as it doesn't allow me to bore right up to the end of the length of the bar.

I'd really like to thank everybody for your kind words so far.  This project has been so much fun, and being new to all of this, I had to get over the fact that I continue to make mistakes.  I found this forum while looking for Corliss plans and I really liked the community.  That is why I decided it was time to start sharing my experience.

Nobody yet has even mentioned how unbelievably disgusting my work space is.  Yes, you have seen bottles of old antifreeze in the background.  It took me quite a while to remember the exact right Saturday of any given month so I could take them to the waste disposal facility.

Finally, please don't encourage me about step by step pictures.  Believe it or not, I'm sparing everybody A LOT of extra pictures!   :LittleDevil:

The week of 2/12/17 brought more excitement as I began to fit big pieces together.

Here we have the end of the cross head and bore essentially complete.  I'll still need to improve the finish of the bore and actually as I type this, I'm preparing to do just that.

This is a pretty bad picture, but shows an important process.  In order to ensure I kept a consistent depth of cut on the cylinder side of the cross head, I utilized my dial indicator as previously shown.

I truly am a simple creature.  It still fascinates me to see how I'm making a perfectly smooth cut at one point in the diameter of the part, yet not even penetrating the outside layer in another.  This is the case despite my strong efforts to ensure the part is centered, square, etc.  I'm sure this is par for the course with cast parts, but...   :shrug:

There's the same location of the part after taken to dimension and you can see that we have a wonderfully consistent cut across the diameter.

Cross slide with inboard head in place.  The dimensions came out very nicely.  It is a snug fit internally and the outside diameter is right on the money.

 :facepalm: I'd forgotten that. I wish I'd read this two days ago. But I'd lucked out and managed to make the part. (A flywheel rim from plate.)

I'm enjoying the thread.  :ThumbsUp:

Yeah, I've certainly had success turning interrupted cuts with it, but I at least know intellectually that it's not ideal.

I'm really glad y'all are enjoying the thread.  I've been getting quite a bit of work done these past few weeks and I can't wait to get this thread caught up with the project.

The week of 2/19/17 saw the completion of the boring of the cylinder and creating precise holes in the crank disks for the crank pin.  I have to be honest and say that the method of aligning the two crank disks was taken straight from rcdon's web page.

I used my dial indicator to ensure the boring bar was running true before spinning the cylinder about it.

..and here's the result.  One more hole to be reamed and quite a few holes to be drilled and tapped.

I think this method for alignment of the drill on center was satisfactory.  I've since learned of a very simple concept where a longer rod with a point sits in your tool holder and pushes into your center punch.  It rotates a short distance from the work on a fulcrum showing a much exaggerated display of how far out of center you are as the long end wobbles.  I need to make one of these soon!

The week of 3/5/17 didn't produce very many pictures, but I did get my valve port reamed.

I decided to trace the cylinder on a sheet of paper, get the center of the cylinder marked out and measure the distance to the center of the valve port.  I was very happy with the results.  Maybe there is a better way, but I couldn't think of one.

Having this tool removed all the aggravation of setting up 4 jaw chucks and other arrangements for me. A very useful tool indeed!

I really appreciate you saying so.  I'll tell you one thing.  When I mounted the cylinder to the face plate, I learned quickly how important it is to cinch it all down very tight!   :old:

The week of 3/19/17 I did my first bit of smaller plain turning as I built my lower valve head. 

I had seen people mark up a cylindrical piece just like this before and now I'm finally doing it for myself.  You may also notice I finally ponied up for some dykem.

You may notice a fillet at the base of this post.  I wouldn't have thought to do this, but rcdon did it, and I really liked the detail.  Little things like this really make the difference in the final product.  Most people who see the engine probably won't notice, but I always will.

With plenty of crappy extra 3/8" extensions and a socket to fit the die, I sawed an extension so I didn't have to wait until I could spend the money on a tailstock die holder.  As of this writing I do have one, and anxiously awaiting the chance to put it to use.

The week of 3/26/17 was exciting for me and the amount of work I completed is the result.  I completed the lower valve head and finally got to turn brass.  My god do I love to turn brass.  Clickspring on youtube has some pretty great videos of primarily brass turning and it is mesmerizing!   :popcorn:

Since I learned a technique to quickly true up cylindrical parts in my 4 jaw chuck, I don't use the 3 jaw chucks ever.  They are just not accurate enough.  However, when it was time to turn brass, I decided to do what I could to get the jaws as accurate as I could.  I don't even want to admit how I went about securing my dremel to the tool post holder, but you can see what is going on here.

This process for tapping threads worked fine, albeit slow.  I just had to make sure I gently followed the pulling of the tap with the rotation of the tailstock wheel.

Before I do too much else, I'll take advantage of these threads to break off the edges of the lower valve head.

Here we go again.  Want to see every single step of this turning operation?  Well, you're here, so I'll just assume..   :ROFL:  Why am I so fascinated by seeing the dykem slowly disappear with each turn of the dial.  You may notice that I didn't go right up to the line.  After I take it to dimension, then I'll get the edge exactly where I want it.  This will be no surprise to those with any experience I'm sure.  But, I didn't think of it.  I had to see it for myself.

Now, the plans call for a much narrower flat of hex.  Again, I followed what I saw rcdon do.  I definitely feel like it is an improvement.  It just makes it stand out a bit more.

I'm very pleased with how this pair turned out.  These are by far the smallest pieces I had attempted at this point and it was absolutely thrilling to see them complete and pretty.  Yeah, I failed to remove the dykem for the picture.

I've chosen to use a different poor man's method of not having a tailstock die holder for this part.  Since the die was round, not hex, I used the flat face of the tailstock (nothing in the morse taper) to push against the back of the die holding it flat against the part.  Then I used my large channel locks to turn the die.  This was actually much harder that it might seem.  I took my time to make sure I didn't tweak the threads and the result was very good.

Great progress - and I admire your drive to find solutions. Although the dremel thing has me nerbvous. Please take care!

Good results though. Interesting idea - grinding the 3 jaws. I have to be honest, having had good success truing up a 4 jaw chuck having studied the technique, I am considering just mounting a 4 jaw and being done with it. With a bit of practice, centering the 4 jaw does not take long, and when you do it often enough probably produces better results than the 3 jaw. Maybe? Food for thought anyway. I do know of some machinists who swear by that approach. Then again I know some machinists who just swear.

Thank you.  While you might see some duct tape in that image, rest assured it was much more secure than just that.  The grinding of the jaws was yet another idea I got from somebody else.  I used a washer at the back of the jaws to clamp down on so that the jaws would actually be as they should during the grinding.

I can tell you definitively that the accuracy I achieve with my 4 jaw far surpasses either of my 3 jaw.  The only reason I ever mount them up is for hex.

The week of 4/2/17 did not produce huge items, but I started being able to fit parts together.  It was maybe even more exciting.

With the piston rod packing nut, I was able to chamfer the top edge after I began parting off, opening up that space to be worked.

There's the result with the bottom part of the flat chamfered, plus a bunch of nasty oil from my chip brush on the threads.  It cleans up nice though!

The week of 5/7/17 is where my blissful progress took a detour.  Not finding much in the way of explanations on how to do layout, I decided on a poor method of marking out the holes on my base and went with it.  The method itself wasn't disastrous, and if I'd stuck with my marks, I probably would have been ok, given the allowances.

Here's the base marked out and mounted to my milling table.  No dykem was used as the base had been marked out for months by this point.  Mounting to a milling table with a single slot can be challenging at times, and this was no exception.  You'll notice my center finder set up to find my first hole.

We may have already gone sideways here.  The problem compounded in this way.  Not feeling terribly confident about the layout, I decided to "double check" myself with the graduations on the machine hand dials, moving from one hole to another.  They are, after all, precision instruments.  When I first ran into the scribe being off from the position found by hand dials, I chose to go with the location found by the hand dials.

Worse yet, when I fail, I fully commit.  Even though I believe I knew it wasn't going well, I chose to continue.

Fortunately, Keith Appleton has described, in one of the many videos I've watched, how to repair cast iron base issues.  I simply need to obtain some cast iron rod, turn it to diameter, and loctite it in each hole.  Once a hole is filled, take the material down to appropriate height of the base surface.  This will take some effort and be a well established and memorable learning lesson for me.

Sorry to hear about that. How come the hand dial positioning was off? Did you go from the wrong datum or something? Or are the dials not right?

Well, it's been well over a year and my self preservation tried to block it.  However, I'm pretty sure it's as simple as the part not being set up perfectly parallel to the table.  :Mad:  It's one of those things where it is difficult to imagine I would have made that mistake, but also difficult to imagine it was anything else.  The dials are good.  I use them all the time.

The week of 5/28 was very exciting indeed.  Knowing I would not create/acquire a dividing head any time soon enough, I developed a plan B for marking precision spaced holes.

The outer head calls for evenly spaced holes while the inner must work around structure.  I used a layout program to draw up the circles and place the holes appropriately.  The plan would have been a good one if the printing had been fine enough detail.  As it turns out, they were not.

My crank disk bad casting became a perfect base for these drilling operations as I would much rather accidentally begin drilling into it than the table of the machine!

I began by drilling a small pilot sized hole, then moved up to the tap size drill for the threads I would later cut into the cylinder.  The reason for stopping at that size will become obvious to those not already aware.

It's a bit of extra work, but totally worth the result.  I found center of each hole and used it as a guide to drill through to the cross slide.

Again, orientation is vital.  These center line marks will be used to ensure that orientation is correct when I begin drilling.

With my line centered in the hole, it's time to clamp it down and get to work.

There's those beautiful results again.  Once the holes had been "transferred" to the surrounding parts, I drilled the holes to final size.  On the head and cross slide, they were drilled to a "slip fit" size for the bolts to squeeze the parts tightly together as they grabbed the threads cut into the cylinder.

Every so often I make efforts to engage one of my kids to see if they might have interest in this hobby.  I'm certain it will be much more interesting when the engine is purring along doing real work.  This is my youngest's hands using a home-made tap guide to ensure the tapping is well perpendicular to the work.  These are relatively easy and even fun to make.  With care, they are highly effective too.

Doesn't look too bad eh?  Nobody who doesn't try to put the parts together will ever know that the holes aren't perfect.  I generally have to twist that outer head around about a hundred times before I find the correct orientation. Fortunately, I won't be doing that too much once the work is all done.

Well, it's been well over a year and my self preservation tried to block it.  However, I'm pretty sure it's as simple as the part not being set up perfectly parallel to the table.  :Mad:  It's one of those things where it is difficult to imagine I would have made that mistake, but also difficult to imagine it was anything else.  The dials are good.  I use them all the time.

Oh yes, I see. Well, I've screwed up many parts in a similar way. Seems like successful machining of parts is about 90% set up and 10% actually working on the part. When I take the time to make sure everything is square and true, the parts come out well. What a surprise.

Cylinder looking great though!

The week of 7/30/17 produced some very important holes.  If anybody's eyes are bleeding, I've done you a favor.  I just don't have that many images to provide for this week.

I test fitted the inner valve head before committing to anything.

The week of 8/6/17 produced very little overall change.  Essentially I milled the flats of my cross slide and drilled the mounting holes.

With so many ways for this to go terribly wrong, I balanced the need to ensure the part was well oriented in the vise.  I had this piece of aluminum which I clamped tight against the bore of the part and used my calipers to ensure it was running true.

Here is another look at the setup.  Mounting the cross slide to the cylinder allows me to ensure there is no unwanted rotation.  You might also notice that I've drilled two small holes in the bottom of the cylinder.  These will have globe valves to facilitate draining of the cylinder when you are done running the engine on steam.  I DO plan to run this on steam ultimately.

You can see this effort coming together well.  There is a need to have a very specific height from this bottom to the center of the bore, so a great deal of effort has been made to complete this relatively small bit of metal removal.  You can also see two bolt heads which will normally be out of site, holding the cylinder to the head to the cross slide.

I'm getting closer here.  I just love seeing the horizontal milling cutter in action or just ready to do work.  It removes metal like a beast and you don't often see horizontal action.

This is a little better view of the finished work.  I have two horizontal cutters and I figured out this one produces a much better finish.  I really enjoy using it.

It's very nice of you to say.  This fantastic community has a lot to do with why I chose to post here!   :praise2:

Last night I realized that I'm either missing a series of images, or I didn't do much in the last year.  It will require a bit more effort to know for sure.  I may get you all caught up sooner than anticipated.

I just read through your build log. Excellent work! Castings can be quite a challenge and you're handling them like a pro. I'm loving your machine tools too. There's a certain pleasure in using old iron.

I didn't notice anyone post, and you may have learned since, but when machining cast iron cover the machine ways with a paper towel or rag. Cast iron chips are abrasive and they'll accelerate wear if allowed to get under machine slides. Cleaning it off can be hard because it's so fine. Best to cover up. Same goes when Dremel grinding on the lathe, or even using abrasive paper to polish. Need to preserve those machines!

Thank you everybody.  It's always nice to hear people validate your work and to one degree or another, I expected that.  However, this particular recognition I certainly didn't expect.  To think that my sharing keeps somebody else excited about the hobby is definitely more than I would have known to hope for!   :stir:

Again, it is very nice to hear such praise.  I certainly don't feel like I deserve it today.  Over the past couple of days I took a cross head which was well set up for success and made a last second change that rendered it beyond what I'm willing to accept.  I believe I will be able to use it to continue forward in the build, but I think I'll take the opportunity to create a replacement from a chunk of steel.  That should be fun and definitely a very new experience for me.

Also, thanks for pointing out about the cast iron.  I've been a touch on the anal side about clearing it from the ways, but seeing the words typed, I realize I need to do more.  I've seen others with paper/cloth covering the ways and I convinced myself that they were just being unnecessarily cautious.  It's time to change that thought process.   :embarassed:

The week of 7/16/17 saw a little bit of advancement.

This is an example of a wonderfully useful and simple shop made tool.  This tap guide helps make sure the tap cuts threads perpendicular to the surface.

About a month went by and the week of 8/20/17 saw some movement on the eccentric yolk.

At this point I did not yet own a height gauge so I had to get creative in finding the center.  I know this setup may look a bit ridiculous, but it did wind up being effective.

The yolk must be drilled, sawn and bolted back together before bringing the bore to size.  These marks will be used for the sawing later on.

A brass connecting rod will be bolted through a hole drilled here, so I had to find center again.  Yes, the casting is less than perfect so you do have to go to a bit of extra effort in finding the "proper" center.  I'm certain this is just what to expect from casting as opposed to feeling like there is anything wrong with the castings.  In that way, castings may save time, but aren't necessarily simply easier.

Let's start with something simple.  After ensuring the yolk was properly vertical in the vise, it was time to drill.

Since I've already completed the dimension of the width of the yolk, determining the center here is a definitive measurement from an edge.  I rather enjoy the process of finding center.  Interestingly enough, with all of the mistakes I make often I decide to do the math for centering in my head and it rarely winds up being a problem.  Though, I generally know if I need to double check myself.

Without a DRO, it makes sense to find center, make a center indentation, spot face and drill through up to the size of the threading size drill all in one go.  Then, I also drill the larger size for the bolt to slip through all the way down to the center mark I made earlier.  If I'm very careful, it will stop right in exactly the correct place, leaving the larger size hole on the back strap of the yolk and the smaller size where I need to cut threads.  I prefer doing as many operations as possible with the yolk set up parallel rather than trying to make sure it is perfect again later.  The chances that it would be perfect are slim.

The week of 8/27/17 saw the completion of the eccentric yolk.

Please feel free to have a laugh at this slitting saw.  I decided to save some money to get further along in the project more quickly.  This piece of junk likely took 10 times longer to get through the material, having to run it so slowly and take such light passes.  I've since replaced it.

Slitting saw work complete.  I'm quite pleased with the overall result.  If you look closely, you'll see just a bit of a chamfer at the lead in to the holes of the clamped piece.  It's almost like I planned it that way.  Well, I actually did!   :old:  With a quick clean up from a milling bit and some tapping, they'll be ready to be clamped together and bored out.

I was very excited to finally be putting my boring head to work.  My little milling machine doesn't have a terrific amount of Z axis travel and there wasn't much room to spare.  But, it was enough to get the job done!   :whoohoo:

There she is in all her glory.  I'll save you the need of asking the question.  Yes, I do consider it complete and yes I do realize that there is still some crust in surface on this side.  When I was milling this part, yet another mistake was made, leading me to have to make a decision.  I decided that there is enough good and smooth surface area here to work well.  Also, while there will certainly be contact made on the side, the force is not horizontal in nature, so I think it's a reasonable compromise.  I'll always see the flaw and remember that this whole project was a giant learning process for me. :embarassed:

The week of 9/3/17 offered another foray into the wonderful world of turning brass.  My god is brass an absolute joy to machine.

But first, I apparently spoke too soon in my last post.  There was another operation to perform on the yolk.  And, in that regard, the part is honestly not complete to this day.  Though I've drilled this hole for the oiler, I haven't yet tapped it.  The reason for this is that I can put off buying that tap, while still mostly completing the part and also I'm not certain what size I'll necessarily wind up using.

I read about this process in the George Thomas' book Workshop Techniques a while back.  For those who aren't already familiar, I'm using a "bar" (drill) of the proper size, to rotate the part around in the vise, milling a bunch of successive flats in order to create a radius.  It's actually extremely effective.

Looking great. Brass is my favorite too, wonderful stuff. Milling the end round like that works great, just have to be sure the bar is tight down to the top of the vise, no chips under it. Works great for larger curves too, can use a smaller bar in large hole for half round caps, just press down on the cap to center the bar in the arc.

That's a good tip.  I hadn't thought of changing the arc with a smaller bar, but it does make sense.

Great work on the PMR #6.

I prematurely bought the kit for one of these earlier this year. Premature because I have not yet built an engine, and need to start off with some simple oscillators to get the feel for it. The kit will keep until I'm ready for it, though, and when I am your build log here will serve as an inspiring resource.

Liking your photos, too - great shots of that Burke (No.4?) in action!

Cheers,

How cool you've chosen this engine too.  I appreciate the recognition, and you have a good eye.  That is a Burke Army #4.

When I started looking for a smaller milling machine, I found that I could buy newer junk or find something like this.  I grabbed an image from google, posted it on craigslist asking if anybody knew of one for sale.  Within a day or two a guy reached out and said he was just about to consider putting it up for sale.

He didn't even realize it had the vertical attachment until after he already gave me a price, and still honored the price.  That single slot on the table can be pretty challenging, but otherwise, I'm loving the machine.

I'll have some more pics up soon.  Stay tuned everybody!   :popcorn:

If any of you are interested in Corliss castings there is a guy in PA here in the US that sells castings and BP's  for that type of engine as well as a very interesting Gothic beam engine in two sizes, a really neat bottle style vertical engine and a couple of other designs. He advertises in the Live Steam magazine and his name is Jeffrey Lehn and can be contacted at jeffreylehn@comcast.net most of his engines require larger equipment as the Corliss has a 14" flywheel. Believe the Gothic half size flywheel is in the 6.5" size range.

I am curious if any others have purchased castings & BP's from him and what are your impressions of his product offerings.
Regards.
Bob

Yeah - I had mine sent direct from PMR and even with the shipping it still cost me £100 less than it would have if I had bought from their British agent and had it shipped to the far-flung corner of the British Isles where I live. I chose it for its chunky size and because it's a real engine.

You reckon your mill is small? I own a Burke No. 0, which is tiny. I restored it a few years ago. They're pretty rare I believe. Here is the very one, in pictures that  I sent to Tony at lathes.co.uk :

http://www.lathes.co.uk/burke/

Don't know how or why it found its way to Britland - may have been something to do with WW2.

The #4 is much more available in the USA and to me looks great. I'd love to own one but they're rare over here.

Old British /American / European iron does not come without its own share of problems, but I agree with you - the quality and sheer beauty win hands down.

I love that #0.  I remember seeing it while learning about the Burke mills.  I can definitely see how it's even more limited though.  I hope it is serving you well.

I've been looking around at what would be involved to get into a bigger South Bend.  While I could get a newer quality machine for a similar cost, I just love the beauty of the South Bends. 

I also find myself very interested in how and why things are where they are.  The history of our world is just so fascinating!   :old:

The week of 2/18/18 saw a little bit of action.  I decided it was time to get some work going on the connecting rod.  Yes, there was a rather significant pause in work there.  After Christmas and my birthday, I had some money to blow!

Here is another lovely shot of the Burke #4 in action, and you may even notice I have a much improved slitting arbor and saw.  What a huge difference.  I'll remind myself to stop trying to "save money" in these ways.  It just causes frustrations.

This is how the surfaces of the big end of the rod turned out after being sawed.  Not too shabby.  I'll use the mill to clean it up even better and I just love how this bronze looks and machines.

It's hard to tell here, but I've got dykem and preparing to scribe a center line.  Using a hand to take the picture, I wasn't able to show the second square being used on the side to ensure the line was running true up the middle.

The week of 3/4/18 was filled by some very satisfying clean-up work on the rod.

I decided to shave just enough material from the sides of the cap and bolted it back together for the next steps.

Finding the center of each end will be important for the method I've chosen to clean up the rod.  My height gauge is such a joy after doing this the hard way on most of my previous parts.

After center drilling each end, I mounted the rod in a lathe dog to turn between centers.

This is the result after most of the turning on the majority of the rod.  Along the way, I found out the hard way that I hadn't drilled deep enough centers when the bit dug in and popped the rod loose of centers.

Chronologically, I apparently decided it was time for some glamour shots.  I took the parts out for hair, make up and styling.  Please keep your comments helpful.  Remember, these parts have feelings too!   :disagree:

Here's a dressing room scene before all the final work came together for the final shots.

Alright.  Time for the main event.  I'm noticing how my make up people failed to remove the dykem.  Rest assured, they will not only be fired, but also black balled in the industry!   :Mad:

The week of 6/24/18 saw the return of the crank pin.  Yes, another several month gap.  So far this year, my son and I performed an engine swap on my Subaru, replaced all belt driven components on my wife's van, went on a 5 day canoe trip, countless other activities and began crossing items off the list with my wife to allow me to bring home my '69 Ghia for restoration.  It's always challenging to make time for the project, but I've been given a deadline!   
:cheers:

Once you've got the part ready for metal removal and you have tooling ready to go, it's time to flip the switch and there's a different kind of enjoyment from all the rest of the steps in the process.

We produce essentially a dumbbell shape here.  As you can see, the outside journal isn't yet up to the scribe line.  It's also not to final diameter.  I decided to play with metal removal using my 60 degree tool, which sadly I have yet to use for thread cutting.   :shrug:

After getting the shape defined, I came in with a left hand tool for making those crisp flat edges on the right side of each protrusion.

The week of 7/1/18 was power packed.  I've been making the time, and I've been really  motivated.  I feel like I'm getting close and my obsession is really rolling full force.

I've seen/heard of people using a parting tool to turn journals, so I thought I'd give it a try.  I did test on a different piece of metal first, so I did have an idea what to expect before I began here.

In this action shot, I'm nipping off the leading edge to nearly dimension after taking all 3 journals to dimension.

Time for a little interlude.  For anybody not familiar, this is a jumping spider.  We have plenty of them here, but it's the first time one decided to join me in the shop.  I just love them.  They have so much personality.  Unlike other spiders, they don't spin a web to catch their prey.  They wait for the right moment and jump at them.  My son got a slow-mo of one in action.  It's fantastic.  If/when they bite, it really doesn't hurt either, so we don't worry about letting them get on us.

At one point, I was trying to get a nice close picture of this guy and he jumped out at my phone, then landed perfectly back on the work bench.  Later I saw him trudging through my huge mound of chips and over to the spinning of the headstock on the outside of the machine.  I warned him not to get too close, but some spiders don't listen to their hosts.  Needless to say, he was quickly flung back into his previous position.  One more attempt convinced him to move on.  I really enjoyed our visit.

After entertaining my green eyed (some have orange) friend, I parted off my crank pin.  Ready for inspection, and nearly complete.

Here is the pin in place, and I'm sad to say that despite all of my efforts, I still wound up having sizing issues.  It seems that even though I used a reamer on the holes in each crank disk, they are very slightly different sizes.  I've decided I'll use bearing retainer to assemble the crank.  Worst case scenario, I can always take it apart and build new parts.  I just need to be able to move on right now.

While I didn't show it, I put dykem just around the edge line, then took the material down to final outside diameter.

I won't spoil the surprise.  Some of you may already have figured it out, especially if you have the same kit.  Isn't it lovely with all of that definition ready to be worked?

Now you might really be able to tell what is going on.  It's the piston.  This kit calls for teflon rings and packing, so these are the lands for teflon.

Earlier, you may remember that I made a huge mistake on my base.  Once I get cast iron rod to fill the holes and start over, I'll need a better way to lay out the holes.  I decided this was it.  It requires joining two 8.5" x 11" pieces of paper, but to begin, we'll just get a layout of the two lands where the pillow blocks will mount.

After tracing out the actual outside of the pillow block lands with the base turned over, I took some measurements and transferred them to this sheet using a ruler and some basic drafting practice.  Laying out this much took an entire hour.

It's a little dark, but here is the complete sheet.  The second part took another entire hour.  However, I'm confident that when these holes are transferred to the base, it will be dead on.

Back to the piston.  Here it is all parted off and looking pretty.

It may not be easy to tell, but the parting off process produced a less than flat surface here.  That's ok, I need to dig out a pocket on this side just like the one on the other side.

No, I haven't put the same image in twice.  Same block of steel, but here comes the next part.  This one will become the eccentric for the valve operation.

This was a much simpler initial part to turn.  The tricky part on this one is getting the hole bored in the side at the perfect location.

Wow, what a nice compliment.  I'm not certain I'm deserving, but I'll take it anyway.  My motivation is super high right now.  More pics to come...

The week of 7/8/18 saw the relative completion of the eccentric, some much needed chip clean-up and the creation of a valve.

Once I felt my eccentric journal was to dimension, I surrounded it by my yoke with some oil.  There was just a little bit of "uncomfortable" resistance through the first few hand rotations, but that quickly gave way to a relatively smooth operation.  I applied a bit more oil through the untapped hole where the oiler will eventually go.  I'm very happy with the fit.  There is essentially no slop.

Next, I touched off a center drill on the part and removed it from the chuck.  I gave quite a few options a dry run to see what I thought would work best.  Ultimately, I set a pair of dividers to length, put a touch of dykem on the part and scratched a small radius into the ink.  After getting the part back into the chuck, I used that radius scratch to find my new center, and ran with it.

After the slightly undersized drill, I finished off the hole in back gear with this pretty little reamer.  The hole should be perfect.

Here is a nice image of the part "finished" in it's shackles.  I do still need to drill out the grub screw hole, but it is largely complete.

I'm not even sure I could tell you why, but I've been a little anxious about the valve.  Starting it was very exciting.  I got a good way into the part before realizing that I had botched the diameter and had to start over.  Oh well.  I had secured a few pieces of 5/8" and 3/4" bar stock a while back after one of my first mistakes!   >:D

Plain turning is so satisfying.  I'm also much more confident in it.  Of course, it helps when you set out to turn the correct diameter.  Aside from that, this was coming along quite well.  I've got the initial hole drilled through at a considerably smaller diameter beyond the desired length of the part and followed behind it with the larger size hole most of the length.  Naturally, the length of this hole was much more important to be accurate.  I used the end of my digital calipers to verify the length of this larger size hole.

There are two holes drilled perpendicularly to the length of the valve.  The outermost hole is 1/8" and will be used to install a roll pin securing the valve to the brass rod indirectly connecting the valve to the eccentric.  The inside hole will be much larger, but I could drill the first hole with the 1/8" making for fewer collet changes.

Before finishing the turning, I got this part as close to perfect as possible.  I generally won't accept  any more than .0005 runout.  It's not super vital here since I'm just removing between lands, but still..

I was just having some fun playing with some of my different tools here, figuring out how best I like to remove material between.  It looks a bit goofy, but I wasn't stressing.  It was actually quite cathartic.

I've taken the middle down to dimension, but we aren't quite there for the last bit over the holes.  Naturally, I'll also need to take down those sharp edges once it's all done, but it's looking rather pretty already.

I'm posting this as a "complete" part picture, but in reality, you'll probably notice that I haven't finished off the top edge yet.  Everything else on the part is complete, but this is after being parted off.

Thanks prop.  Yes, in fact my next post will be the last of the images I have downloaded to the computer.  While a lot of the parts look "complete," I've got to go back and actually complete quite a bit, never mind fixing more mistakes than I'd care to admit.

The week of 7/15/18 saw some part review and work on a new part.

I finally got the parts together so I could hone the cross slide.  Here is a piece of PVC getting ready for me to turn it into a honing tool.

You don't see much of the PVC at this point.  Much like rcdon described, I taped some paper to the pipe, observing the rotational direction, and added more sheets as necessary to bring the sandpaper out to a functional diameter.

Not having created the cross head yet, 1.502 tells me exactly where I need to be when turning the head.

Now that I know where I need to be on the head, we can begin to machine it.

With the base of the head already finished to dimension, after machining out the flat here, I was able to accurately place the hole.

Here is a better picture of that hole after drilling the size under the 5/16" reamer.  The part is coming along nicely.

If you look closely, you'll see my center mark, but also I have scratched in the diameter for visual reference.  You can see that the cast was a bit off, but there is plenty of material.

This may be an effort in vain, but I thought I'd remove some more of the material on the big end of this rod.  It's just fun too!   :LickLips:

If you look VERY closely, you'll see a little bit of light between the square and the part at the top.  Somehow, I was not machining squarely.  When I realized this, I took a closer look at my setup in the vise.  I was placing the part on top of a couple of tool blanks so I didn't yet have to purchase parallels.  Even though I ultimately realized that there is a very small amount of variance in width from one to another, that was not the issue either.  It seems the top of the head was not perfectly parallel to the bottom.  So, when I set the part in place, all looked well.  However, when I clamped down, a small gap formed between the top of the part and the tool blank beneath it.

Using my height tool, I determined the variance, and found that the tip of a razor blade was about the right width.  I could not find my feeler gauges.

I was on a good path.  I also decided to use this fly cutter.  Unfortunately, I did have some issues with it, but other bigger issues became more important.  Rather than simply set off on this path and trust all to go well, I continued to check and adjust as I went.  Later I found something better to use than the razor blade tip (not shown) and got the part to square.

This is such a huge moment for me.  I have been so excited to mount this head to a thread, mount it in the lathe, and turn the outside to dimension.  The part is such a unique departure from other plain turning of cylinders.  Here is a cylinder with the sides cut off, but even more interesting than that.

Never fear!  I have been slacking with posts to the forum, but not as much with effort in the machine shop.  I still have trouble calling it a machine shop.  It's really a complete mess of a space where a very small third car could get parked in theory.  But, I digress..

Over the past few weeks, I've had some pretty exciting developments and one major point of frustration.   :Mad:

Basically, I'm down to fixing stuff I screwed up earlier, improving fit and a handful of final parts, etc waiting on funds.  I got in the replacement pillow blocks for the engine and got right to work beginning by giving them a few good reference surfaces.

These babies will come down to 1.375", so I've got plenty of material left.  I have learned THE HARD WAY not to get too material removal happy to early.  Have I already mentioned how life changing this height gauge has been for me?

Ok, now that we have both pillow blocks and pillow block caps "to dimension" it is time to layout marks for drilling.

It's a little difficult to see the mark in this light, but you see I've used a machinist's square to ensure the part is perfectly vertical before making my scribe.  Otherwise, precision is just a word with no real effort.  Heck, even with the effort, precision feels like a loose term to me at times.

I took my time, found what I wanted to be my center reference points and scribed 2 cross hairs on each part for the two bolts which will ultimately hold the pillow block cap to the pillow block.

Here is a better view of the sharp pointy object efforts.  With all 4 holes drilled for each pillow block assembly, it was time to get references for the 4 mounting holes in each pillow block.   :embarassed:  What, there are only 3 holes in that picture?  Oh yeah..   :facepalm2:  Despite all my efforts, the fourth hole did not get started in the right location.  So, no problem!  I'll drill it from the bottom.  Problem solved!  ...or so he thought..

I'll kill the suspense here.  That fourth hole, when drilled from the bottom..  Well, it too did not get started properly and I decided it would be better to fix it from the top.  I used some "quick steel" a friend gave me to fill the divot flush and try again.  While the "quick steel" didn't ultimately provide a solid surface as I had hoped, I was able to use a larger sized center drill to sort of force the hole where I wanted it and all was well.

Now was the time to transfer those holes from the blocks to the caps.  This will be the second time I've used cynoacrelate glue, then remove with heat.

I used my height gauge and squares to ensure the pillow block was properly perpendicular to the drill before I began hogging out the hole.

With a hogged out hole in place, it was time to bring in the big guns.  I was only able to get a 7/16" hole as my 1/2" was just too long!  Oh wait, I can't fit this boring head.  The Z travel on this machine is pretty limiting.  It provides opportunities to get creative.  For this, the only creativity was to stop using that vise and get closer to the table.

If you look closely, you'll see a machinist's square and a feeler gauge peeking out from under the "top" (sideways) of the pillow block.  If you recall from a previous photo, the edge where I am drilling is stepped in from the edge of the base of the block.  I needed to build up a shim here.  I used my height gauge to find the difference between the two and my calipers to ensure it was the right amount.

Here I am performing a final sanity check.  Ultimately this hole will accommodate a 3/4" bronze bushing, but I need to "sneak up" on that dimension "in situ" when the pillow blocks are mounted to the base to ensure concentricity in the final holes.  So, .742" is perfect.  Later, I'll learn that I can simply unscrew my boring head from the shank and get it out of the way for much more reasonable bored hole dimension sanity checks!   :old:

Here is a shining example of one hesitation I had about sharing my progress with anybody.  You'll notice, that despite my efforts, this hole is not centered in the casting.  It is centered relative to the mounting holes, just not the casting.  I'll likely adjust this later.  Ok, at least this hole is the diameter I want.

Here's a look down my fresh hole.  Without sharing too many pictures, I'll explain how I had to adjust to make this work.  The boring tools I have are several different lengths.  I had to begin with a short one, because a longer one would not have enough Z axis travel and would have to begin down in the hole.  That obviously won't work.  So, after getting .9" down in the hole with the shorter tool, then I was able to use the longer tool to get the rest of the ~ .4".  It was a bit wacky, but totally worked.  Naturally, this wouldn't have been a reasonable way to take the hole to final dimension.

Ok, so that's two pillow blocks ready for final reaming in situ.  By the way, the first of the two of these took over a week to complete.  This improved as I figured out my process better.

I forget if I mentioned it before, but this crank pin had a minor issue.  Minor issues on bearing surfaces are pretty major.  I realized that the parting tool I used to "finish" the bearing journal in the center was not precisely square.  This left one end of the journal ~.002" larger diameter than the rest.  Naturally, this is no way to fit inside a rod cap.  Also, it seems the hole in the rod was not quite big enough.  I used a piece of rod I had happened to turn down to a very nice size for this purpose, and wrapped some fine sandpaper around it, then honed out the hole a bit.  Little by little with frequent testing found a very nice fit I think.

That wouldn't be the only fitment issue on this rod.  The other end was binding a bit on the cross head.  I had to adjust both the rod and head to get this right.  Again, small efforts with regular checks is the way to go here.  Also, when you check the fit, rotate more than just a few times, or you can easily go over your dimension.

Now, I don't have a cylinder center finder tool, so I had to improvise.  I'm not patting myself on the back too much here.  I've seen about 15 different ways to "find the center" from other people, and this wasn't that complicated.  Here, I'm using my height gauge and a magnifier to twist the part where the "bottom" of the hole is at the lowest possible place.  This helps to find my perfect vertical.

The v-block is 1.462", so set my caliper to .731" so I can find my horizontal center.  If I were to set my square 90 degrees of this direction (as I would tend to want to do), there would be a gap between the work and the edge when I scribe my line.  Instead, I went straight on and held everything rigid.  I used a big heavy block of steel with another square up against the side of the v-block so I could get my caliper in there well with enough space to scribe the line.

With the line scribed, I was able to put the part in my vise and compare it to the square to ensure I'm drilling as I intend.  I had put some dykem on the top of the journal, and intended to slowly raise the table until the cutter barely began removing dykem to find my center.  However, I found an easier way.  After using my edge finder on the front of the part, I put my center drill in the machine and pushed the Y axis back .1" (half the width of the edge finder) and used my magnifier to see when the center of the drill was directly lined up with the line at the top of the edge.

With this done, I continued to move the Y axis of the table half the width of the part for that center.  Bringing the table nearly as far forward as possible made it impossible to see the mark I needed once I got there.  The web of the handle was in the way, never mind the vise and table hovering over the top of it.  I was reminded of the ability to line up 90 degrees clockwise around the machine.  So, I took the position to .020" before where I needed (I could still see the marks on top at this point), reference the scale on the side of the machine, subtracted twenty, and voila!   :cheers:

With a #25 drill in use, I completed the hole for this grub screw.  Life is good.  Wait, I couldn't be done just yet.  Everything is going soooo well!  Let's get the tap and begin turning it, using a collet to keep it vertical.  Yes, the collet does cover the square at the top of the tap.  I used pliers to carefully twist until I had a decent beginning to thread bite on this tapered tap.  It was good enough and worked well.  I was able to remove the part from the vise and use a hand tap to keep things going.

All along the way, I turned the tap back well beyond where that last twist began, then forward another 1/4 turn before repeating the process again.  I also used cutting fluid along the way and took my time.  All was going so well..   :hellno:  Then, SNAP!  OMFG.  The tip of the tap was well through the bottom of the hole and I now have a broken tap all the way from the top to the bottom of this hole!

...  I still have trouble calling it a machine shop.  It's really a complete mess of a space where a very small third car could get parked in theory. 
Sound like a shop to me!  :ROFL:

You've done a lot of work here!

Sorry to hear about the broken tap.  I have certainly been there, done that. And it is no fun!  :Doh:

If the tap is through the hole, can you gently screw it out of the hole?  You have to be REALLY careful - the tap is very brittle and will break off quite easily while doing this.

There's also the old Alum trick that I've used before. Not sure it will work with cast iron though.
Depending on the size of the tap, there are tap removers that will reach between the flutes of the tap and help you twist it out.  I've never broke a big enough tap for that to be an option.  Its always  a teeny-tiny one.

If it wasn't a casting, you can always start over again as a last resort.

Good luck getting it out.

Great update and kudos for sharing both wins and boo-boos.

Bummer on the tap.

The eccentric looks like steel?

Unfortunately I can't help with tap removal. I've only done it on aluminum (with alum).

I love that #0.  I remember seeing it while learning about the Burke mills.  I can definitely see how it's even more limited though.  I hope it is serving you well.

I've been looking around at what would be involved to get into a bigger South Bend.  While I could get a newer quality machine for a similar cost, I just love the beauty of the South Bends. 

I also find myself very interested in how and why things are where they are.  The history of our world is just so fascinating!   :old:

Hi -

Wow, it's a small world!

TBH I haven't used the '0' so far. I am planning to convert it back to flat belt as I am building a lineshaft at my workshop in France and aim to hook the Burke and  some other appropriate machines to it when it's ready.

You are right about history, and what a gateway into it this machining  thing is!

Still loving your pics of the #4 - they have a classy look to them.

Also great seeing your PMR develop...

Cheers,

gary

It's been a while since my last post, and while time has been scarce overall, I have accomplished a few things.

I learned by watching Keith Appleton that one could fix imperfectly created holes in their cast iron base by plugging the holes with cast iron rod, using loctite.  So, I decided to give it a go.  However, to say I have a limited budget would imply that I have a budget.  I have the opportunity to spend some money randomly from time to time.  So, rather than buying cast iron rod, I cut up some "scrap" pieces I had in the shop.

Without proper lathe dogs, I had initially set out to make my own, but quickly decided to go this route instead.  These two aluminum chunks are an old tap handle arrangement I inherited from my grandfather.  It was tough deciding to put them in harm's way, but I'm certain he would have been happy to see me putting them to use for whatever sensible operations.   :agree:

My slitting saw was able to produce perfectly reasonable results in cutting my plugs to length.  This was not the quick way to resolve the issue, but it was coming together nicely.

With my first hole plugged, everything is looking quite nice.  I think all may just turn out ok in the end!

More plugs installed, and the loctite I chose was 680.  It's a bearing retainer.  I thought this sounded perfect.

With the great failure in tapping my eccentric, it was time to make another.  Again, being as cheap as possible, I chose to see if I could use the last bit of 1 - 5/8" round stock provided in the kit.  I would not recommend this to others, but if nothing else, it was a nice learning experience.

Everything being very disjointed, and trying to meet my mark for having something meaningful to show at our New Year's Eve celebration, I put back together my horizontal milling cutter and cut some keyways into crank rods.  Here's a before next to after rod for illustrative purposes.   :)

This next one could require some explanation for those familiar with the model.  Since I overshot my .002" undersize bore on the crank disks, I can perfectly fit 5/8" rod through the center of these babies.  This allowed me to set the crank pin in place perfectly aligning the crank disks while the loctite cured.  Why did I use loctite I hear you collectively wondering?  Remember how I overshot the bore on the crank disks?  Well, I overshot the turning operation on the pin as well.  Worse yet, this was my second attempt, so rather than make a third, I decided to see if bearing retainer will hold.  If not, I'll rebuild it later!   :Mad:

Now is the time for the return of the aluminum handles tap wrench.  These little threads are so adorable.  I just loved cutting these holes.  You may notice I placed the upside down tap guide over one of the holes to illustrate how I used it to assist in the creation of these threads where I didn't have a large enough flat surface to use the other side.

Here is the bottom of the cylinder, freshly cut holes with "close" nipples installed.  See how freaking cute those things are?  This is temporary, as I'm just not ready to machine the tiny globe valves any time very soon.  I'll be cutting down some brass rod into threaded plugs for these holes, and returning to the globe valves later.

It took a while, but I was able to spend a little money, and pick up some brass rod to make the piston rod.  This looks like a sound operation, right?  Hold rod in 3 jaw chuck, and use tailstock die holder to cut threads.  What could go wrong?

Things are really starting to come together nicely.  You may or may not be able to tell, but that piston rod got gouged up a bit.  As it turns out, it's not the end of the world.  I had to remove a bit of material for it to have the appropriate fit through the gland nut anyway.  No matter how I try for perfection, I'm constantly being reminded that there is no such thing.  I'll just keep getting as close as I am able, and <zen breathing> keep pushing forward!   :rant:

Everything coming together pretty nicely, we now have the piston directly connected with the cross slide via the piston rod.  This was a bit tight at first, and I wound up realizing that it helped to back off the gland nut just a bit.  Then, after a touch of oil in the cross head, a few passes back and forth made me a believer.  This thing will work!

Here came a real treat.  You may notice my shop seems much more substantial.  No, this was time spent at my friend's shop.  He graciously allowed me to spend the afternoon on his "real" milling machine.  Holy crap.  Do you see how I can just clamp the entire base?!   :LittleAngel:

The reality is that my single t-slot machine really cannot allow me to get a consistent finish on the base, so I finally accepted the need to use a larger machine, and took up the offer to use the space.  I'll be returning later to use his press, and who knows what else.  I started my time there by getting the bottom of the base nice and perfectly flat!

With that quickly knocked out, it was on to making the top perfect.  Nothing was WAY out, but I needed to knock down the plugs sticking up from the surface, and there was maybe .015" difference between the highest and lowest spots.  Again, not WAY out, but way too much.  This was a necessary upgrade to my operation!

Just look at those results.  I decided one of the 12 holes was in a good location, so I only had to mark and drill the other 11.  I have no pictures of this, but I taped together two 8.5" x 11" pieces of copy paper, and detailed out the hole pattern.  Then, we used a bit of spray adhesive to position it on the base before using a center punch.  I took my time, and this turned out very nice indeed.

Ok, you guys are getting the good, bad, and ugly here.  While this all went pretty well, 4 of my 11 new holes were not up to the task of being drilled and tapped.  The holes I plugged were sometimes way off, and other times, barely off.  Sometimes the plug held fine, and others, not so much.   :Mad:

I do have a plan B.  Enough time had passed, and I've ordered some cast iron rod.  I know, it seems like only a paragraph ago when I said I wasn't going to buy any.  Well, that's true, but in reality it was a couple of months or something.  Still...!   :wallbang:  So, I'll drill out larger sized holes in the base, tap the holes, and cut threads into the cast iron rod plugs.  Then, rather than using a perfect cylinder slip fit with loctite, I'll be installing them with loctite on threads.  I do believe this will wind up working rather well.

Even though my crank isn't complete, and I only have one screw for the right pillow block, I just wanted to get this all put together, and make sure the relationships looked good.  I believe they do.

I was actually able to make a short list of every remaining step, and put an * next to those items I can actually do with what I have.  I decided to make the piston rings.  They are far from perfect, but should be plenty effective.  However, my piston is such a beautiful fit in the cylinder, there isn't much room for them.  It is a very tight fit with the piston rings installed.

I need to determine whether there isn't enough clearance between the piston and cylinder wall, or if I need to cut my piston ring lands a bit deeper.

One other thing I could do was to cut gaskets.  Heck, I was even able to do this in the house!  You'll notice they are certainly not perfectly round holes.  I used a compass to mark them, but then had to freehand cut them with a razor blade.  I just cannot go purchase every tool it would take to make everything "perfect," so I made the decision to allow these to be ugly since they will still be plenty effective, and won't show!

Finally, this is a pretty bad picture, but I decided to figure out a way to use my first eccentric rather than the replacement.  The mating between the first eccentric and the yoke is just SO DARNED PERFECT, and also, the replacement wound up being dished on one side where I failed to take a really good look before getting started on the operation.  One of the employees at my friend's shop suggested a 1/4" carbide end mill with a VEEEEERY slow feed.  This worked perfectly, and my broken tap was removed.  Then it was a simple matter of cutting new larger threads, and now I need to source a new grub screw!   :cheers:

Well, that's about it for now.  Here I am on 12/29, and I accepted several days ago that I will not have enough to demonstrate on 12/31.  However, I really am pretty far along, and I'm hoping I'll get this thing turning very early into 2019.  I'm slow to add to the site, because honestly, what little time I have to myself, I try to get into the garage, or spend it with my family.

Also, if you took very close notice in some of the pictures, it may not surprise you to know that I did start another project.   :embarassed:  I was able to talk my wife into allowing me to purchase an Atlas shaper in need of much love.  As of today, I have it essentially completely broken down, all screws, bolts, pins, gears, etc have been degreased and cleaned.  Most of the paint has been removed from most of the pieces.  I have one very stubborn part (S7-103), and then I can remove paint from the ram too.

After I source a couple of scotch brite wheels for my grinder, I'll commence to really cleaning up the bits and pieces, and possibly even polish certain hardware.  Then, it will be time for paint and assembly.  I am still treating the shaper restoration as a secondary project to the engine though.  If I don't maintain some level of order, it will be total project chaos!   :zap:

Thanks for viewing, and as always, feel free to comment, critique, etc.  I am OBVIOUSLY an amateur, learning more all the time, and I welcome advice and insight.

This engine build is going pretty darn well for a 'first' engine! I love your presentation and the fact that you don't hide the bumps and bruises. We all learn by watching and I'd rather watch someone else 'learn' than have to repeat their 'learning'.  :facepalm:

Hang in there and keep on keepin' on!

I need to start this post by reiterating what a superb bunch of people make up this community.  I truly appreciate all of the encouragement, praise, and consideration of any kind.  It is very difficult for me to share all of my mistakes, but you guys make it as easy as possible.

My previous efforts to repair mistaken hole locations in the base were partially successful, but four of the holes needed more efforts.  I decided that a slip fit plug wasn't as likely to do the trick as a threaded one, so I got some 5/8" cast iron rod, and threaded it in the lathe, then cut discs of about 1/4" long each.

My friend was gracious enough to allow me to use his shop again on this particular day, and I was able to do some things I couldn't at home, while others were simply far easier.  Mind you, that huge efficiency gain was thwarted.  It seems one of the employees has acquired a new shop mate.  As I understand it, she is a regular at the shop, and productivity has dropped sharply since her arrival.  I was no exception.

I was also finally able to finish assembly of the crank.  If you recall, I had previously assembled the two crank discs to the crank pin, but the crank rods remained.  Here I am using the shop press to make simple work of this operation.  I had big plans of making this perfect, but I didn't bring certain tooling with me, wasn't finding it in the shop either, and time was slipping away.  So, the keyway in one crank rod might not be absolutely perfectly aligned with the other.   :facepalm:  I'm learning to get over such things.

Later, at home I was able to glean the tiniest bit of interest from my family, so assembled just about as much of the engine as i could while doing some fit tests.  It's getting pretty exciting.

While I was rummaging through tooling at my friend's shop, I found a set of letter and number stamps, and decided to use them to assist with pillow block orientation.  This will prove very useful as I begin to finish everything.

Here is my crank with connecting rod splayed out.  I just wanted a picture of the two together with nothing else.  There's something about the pair that seems to stand alone to me.

While at my friend's shop, I drilled out these holes, but I was trying to allow others to have plenty of time on the machine too, so you can see how I didn't really complete each hole.  Later, I finished each hole with my hand drill.

After completing one hole, I cut in the threads, and ran a "dry fit" of the plug.  It worked out just as I had hoped.  Yes, you may notice that the hole for one of the plugs leaves a fair bit of the wrong hole still exposed.  I struggled with this.  I was trying to not get too close to the edges, and I think I really should have gone closer.  Here will be another opportunity for me to have a possible learning lesson.   :cussing:

Here we are with all of the plugs installed, using loctite.  I can't wait to get these machined down, drilled and tapped corrected holes.

It's taken me a while to get here with the fit of the piston and rings.  I spent a fair bit of time taking measurements from different angles and depths of the cylinder, and around the piston, to ensure the tolerances were where the plans instructed.  Ultimately, I took a chance, and decided I just needed to remove some thickness from the teflon.  This turned out to be correct, the best I can tell.  I think I've finally got a good fit on them.  While I am mechanically inclined, every bit of this is new to me, so it takes me time to feel good about some of these decisions.

Here I've assembled the entire cylinder, valve, and cross head assembly with all four heads installed, to ensure I get travel without binding.  It took just a bit of effort up front to get everything to seat in place as necessary for the movement to be smooth.  At this time, it still requires a fair bit of effort to get the mass into motion.  I'd like to get some compressed air into the intake so I can see how much pressure it takes to push the piston.  It's certainly not 100%, but I'm very close.  When I can finally mount everything to the base, I'll be able to do better tests.

Today I ordered my adjustable reamer so I can finish out the pillow blocks to trap the bronze bushings.  I'm getting so close, it's really starting to get exciting!   :whoohoo:

Lookin' good! That half hole on the base? JB Weld. The bottom is on the bottom and the top is covered by the mating part. Degrease and fill 'er up!

Hey, that's a great idea.  I've heard of people using JB Weld for all sorts of things.  I imagine it will get out of my way well for the bit of threads that will be cut into that area.   
:cheers:

Also, on a side note, I'm getting really far along on my metal prep to paint my Atlas 7" Shaper I'm restoring.  I have never done much with paint, and what I've done has generally turned out less than great.  I'm just going to take my time, and be willing to redo as much as it takes to turn out right.

bwal,

Terribly sorry about the delay.  I've been all over the place, and my "feverish pace" diminished after not meeting the New Year's goal.  Do I have pictures?!  How about way too many?

Actually, I've been looking for a place to post them, but I don't think there is an appropriate place on here, and I think it would be white noise on practicalmachinist.com.  Any ideas?

Until then, here are a few pics..

Pretty early on I had to decide whether this would be a functional restoration, or if I was going full on.  I think you can guess which one I chose.  Not only am I chasing all threads, but removing badges, etc.

Look at that ram.  It's really coming along.  I've got a couple of screws to extract, and one or two badge securing pins as well.  But, I'm just about ready for paint on darned near all of the parts.

I've also got a maroon scotch brite wheel coming to "buff" all of my screws, rods, etc.

Lookin' good! That half hole on the base? JB Weld. The bottom is on the bottom and the top is covered by the mating part. Degrease and fill 'er up!

Pete

That's a great idea Pete.  I think I'm going to try to get some JB Weld today.  I've managed to get my milling machine to work well enough to scrape down my plugs to within about .0005" of the surface.  I'll put in some JB Weld, let it cure, and maybe take a file, and finish it off.

That shaper is going to be a beauty once you are done!

Nice little shaper and looking better already. If you want to document the restoration I would suggest themachines and tooling sub fora.  Let me know if you wish and I can move the posts about it there for you.

I really appreciate the support.  Everybody has been so supportive and helpful.  This is why I wanted to post my shaper restoration here.  You guys have one of the best groups of people I've found!

I started a thread on my restoration here.
