Just a reminder...although many of you know this about me already...I THOUGHT you looked familiar....!
I'm still very much a newbie. I've made all of 5 small engines from kits and some odds and ends.
Suggestions :noidea: and corrections :slap: are always welcome and hopefully many laughs and fun can be had :lolb: (at my expense and yours as well).
I'm such a newbie that having drilled 4 holes, sliding in the crank, and feeling how smooth it turns is a major accomplishment and so I sit here celebrating :wine1:
Which reminds me...where in the heck did T hide my tu-tu?

Coming along nicely! Isn't this more fun, satisfying, relaxing, etc than that werk, um, wurk, err, whatever its called, thing?!
If you have them, would a set of 1-2-3 blocks give more surface area and wider stance for clamping to table and part? Either way, make sure those clamps are on tight, don't want any vibration to wiggle them loose (not that its happened to me... today...)
Nice progress zee!! Making me feel guilty for my lack of same
Fifty days Carl, but who's counting :cartwheel:
Thanks.What? No Pictures? :facepalm2:
I managed to drill the holes in the cylinder mounts. I was pretty careful but both main holes are just slightly off center. Height is right.
Not sure what happened.
I'm thinking things will be okay though. We'll see once I do more on the cross head.
Thanks for the help.

You've seen the base. Now it's a base with a couple of non-centered holes. So what's to see? ;D
Worked on the Cross Head Caps. Four of them.Thanks Carl, looks great! :Lol:
I still need to get better at spotting and centering but they should be fine.
1st pic is drilling the oil hole and mounting holes. I won't be making oil cups.
2nd pic shows the caps installed.
3rd pic is the hole that Chris wanted to see.
When you say you aren’t making oil cups; are you going to buy them :shrug:? Hey, I have about two tons of leaf and horse manure ready for composting: good deal, almost free, shipping only buddy 8) :lolb:. P.S. I’m cheating tonight; someone else can cook the pizza. Twelve hours of cooking is enough for me and I ain’t in the mood for ribs anyhoo :lolb:.
Off to a good start Carl :ThumbsUp:
I appreciate you don't want to make oil cups but have you thought of buying a couple, I think they improve the look even if they are just decorative and they cost very little. :)

Thanks Gas_mantle. Well if by improving the look means silk purse from pig's ear...it would be worthwhile. ;D
But it might not be too late. I'll think on it as I get further down the road.
The oil holes are currently drilled to 1/16. I suspect that means there's still meat to thread.
If I do make the oil cups...what diameter oil hole should the cup have?
And then I realized a problem. There's not one sodie pop or beer can in the house.
So I can't cut some strips to hold the part when I flip it around.

Wait for trash day and raid your neighbors' trash.
Lots of canned fish (e.g., sardines, teriyaki mackerel, anchovies, etc.) come in aluminum cans now. (BTW, save the cans and cut sponges to fit them, some weights under the sponge and you have nice little soldering iron wipers.)
Old beach chairs with aluminum tubing frames.
Scraps of copper pipe or chimney flashing scavenged from recent construction.
Old, pre-zinc pennies.
Discarded cookie sheets and picture frames.
And, before you laugh, I've used all of these at one time or another in my career.

Purely out of respect?
All neat ideas. Over the last couple of weeks I've been internet cruising various hobbies. Not that I'm leaving this one...it's all about ideas and an interest in what people are doing and come up with.
It's just fascinating the things people come up with to make miniatures, dioramas, etc. How they re-purpose items.
Do you mean play in the hole zee? If so that shouldn't be a big issue. Maybe get even allow you to line things up better in the end.
Is that Frog tape?
I've used the 'delicate surface' version of Frog Tape, comes off of airbrush painted surfaces very well, but holds just enough to mask for the next coat.Is that Frog tape?
No. Tamiya Masking Tape. Generally used to mask off plastic models for painting.
I had gotten it so I could paint a balsa kit of an Me109 and a Stuka 87. Both rubber band powered.
Haven't finished the Stuka. The Me109 looks like crap and will be used to let the grand-daughter have some fundestroyingflying it.
P.S. That tape was probably not a good idea for the balsa model. When I took it off, a nice square of rice paper came off too. :cussing:
I like the idiot proofing too.
Zee, what are the flats for? I looked at my single cylinder version and the con rods don't have that, but it was built a lot of years ago too.
I try not to think about it :lolb:
Green is also 609 & 290; maybe the 603 is the old 609?
The 290 is the wicking variety and can be handy at times.
Red is 271, green retaining compound is the 603. The colors are printed on the containers, but the liquid itself is that color.
All of them cure in absence of air, so any left on surface wont dry, but easy to wipe off.
Thanks Gas_mantle. And you've reminded me I have a bottle of 638 on the way.
Just look at all the things you are learning on this build Zee. Both about machining and about your new tools. Still following along and think you are doing great.
I attended a small machine/product show a couple of weeks ago and talked to a Loctite guy. I generally have been using 620 (green) and was interested in the difference with 638 that a lot on here use. It seems they're pretty similar except for the cure time.
620 is not contaminant/oil tolerant and only comes in 250ml bottles..
And 50mls (https://www.ebay.co.uk/i/272584260851?chn=ps&adgroupid=13585920426&rlsatarget=aud-133395220626%3Apla-142405550706&abcId=&adtype=pla&merchantid=115585453&poi=&googleloc=9045864&device=c&campaignid=207297426&crdt=0) and 36mls (https://www.ebay.co.uk/itm/Loctite-38652-620-High-Temperature-Bearing-Mount-Bottle-36-milliliter/123055456855?_trkparms=aid%3D222007%26algo%3DSIM.MBE%26ao%3D1%26asc%3D20160908110712%26meid%3D74f30ddc458f470d98eecc5a6bb4ed4b%26pid%3D100677%26rk%3D4%26rkt%3D4%26sd%3D272584260851%26itm%3D123055456855&_trksid=p2385738.c100677.m4598) ;)
Been waiting to say this back to you for a while, how do you get so much done? Do you ever sleep?!
Thanks Bill.Like a certain coyote catapulting an anvil? :Lol:Been waiting to say this back to you for a while, how do you get so much done? Do you ever sleep?!
I hate to burst your bubble (no I don't) but you don't have a monopoly on shop elves.
And I have better cookies.
Taken a count of your elves lately? ;D
I see a new face here every few days. I wondered where they came from and why but when I ask...they just look at the floor sheepishly and mumble something about crap cookies.
If that results in a cookie war...so be it...it can only result in better cookies for everyone.
(But it sounds like...from the elves...you have a ways to go before I need to worry about improving mine :lolb: )
Hm....I see a cartoron reference coming up.
This ought to be Really confusing to newcomers here... :ROFL:
For Chris...

Studs. :facepalm2:Might as well try putting them in in this engine. Remember, practize makes prefekt.
They are certainly in my future. For this engine though...well we'll see how it turns out.
Easy to make, just cut the head off a long screw for the stud, add a nut. If you get adventurous, make some scale looking nuts from hex. If not, hardware store nuts to start out.

Better yet, Loctite the nut to the headless screw bit and use the resulting structure as a screw that looks like a stud. That's how it's done in the TLAR workshop.
This is one of those hobbies that you can learn some by reading , but it needs doing to really get it.
Zee, things like good in the pictures. If you think the dimples will be a problem, the heads will cover them most likely, but if you worry about sealing the heads for ait leaks, you can always add a thin paper gasket for insurance.
True for most anything in life. People often ask me about learning to program. "Start programming" is where the answer usually ends up. Pick a small project and do it.
Change 'programming' to machining, wood working, writing, dancing,...pretty much anything.
American Indians intentionally place a,fault in their jewelry so that the piece is never perfect. Sounds like a good explication to me. I've used it myself. :pinkelephant:
As Cletus said, you ARE on a roll Zee. Nice work, but you realize you are setting a precedent now...no more newbie excuses ;D
:thinking: Hey Zee have you thought of finding a box to put all your made bits in? That heap looks like bait for the wrong sort of Workshop gnome :paranoia: ... they will be just waiting for you to knock it so that they can practise their cricket fielding and scurry off with the bits you have made :facepalm:
P.S. Zeeprogrammer :stickpoke: should it not now be Zee_retired_programmer ;)
Then who is that elf behind you? :LittleDevil:
Not to worry. I have a very effective anti-Chris's elves/gnomes system in place.

Carl, I don't now what you intend to use for piston rings but I find rolled up graphite yarn soaked in oil works great
Two parts closer to a runner Zee. The pistons look good from what I can see in the pictures.
And maybe a bigger sign? ;)
Remember that 3D printed spindle stop I made?
Remember the little 'idiot' sign I made to remind myself to remove the spindle stop before turning on the machine?
Remember you might have said to yourselves, "yeah, I'm sure THAT will help"?
A clever idea for use only by a clever person.
I'm printing another spindle stop.

Maybe you could use a Sharpie to write "remove spindle stop" on the inner surface of your safety glasses' lens?
Brings to mind a sig I saw on another forum...
A few learn by reading. Some learn by observation. The rest have to pee on the electric fence for themselves.

Tie some Tutu elastic to your spindle stop and fix the other end to the ceiling that way it will have to be held in place and will automatically release ;)
Do I have the terms correct? I'm calling that thing on the spindle a backing plate.
Thanks.
Hi Jason,
I re read what Zee posted & it reads that the 4 jaw had a back plate, the issue being that the 4 bolts that hold the chuck to the backplate hadn’t been installed! The 3 jaw has its own ..... with bolts.
Both insert into a lock ring to be held on.
That is right Zee isn’t it?
Cheers Kerrin
Don't worry about the broken drill, not an uncommon problem - either from moving parts or when they get dull, it happens. I've taken to buying multiple spares of some of the most used sizes
At this rate Zee, your best be thinking about getting materials on order for the Stanley Steamer :naughty:Ooh, yeah, we'd love to see that! :stickpoke:
Bill

Yous can call be Zeep, yous can call be Carl, but you DON'T calls be Chris.
The Stanley is Chris' job. Go give him a poke.
And keep doing it.
:lolb:
Nice work Zee. Hey, at least you were able to retrieve the broken bit. I think a Stanley Zeeamer would be a great project for anewold retiree with all that time on his hands :stir:
AHA! Zee finally admitted that my elves are helpful, rather than evil little beasties! :lolb:Nice work Zee. Hey, at least you were able to retrieve the broken bit. I think a Stanley Zeeamer would be a great project for anewold retiree with all that time on his hands :stir:
Please refer to previous post. ;D
And he's got elves to help.
Speaking of the Stanley...If I have a dream...it would be a 4 cylinder VW air-cooled engine for a 1965 or earlier Beetle.8-track?! Wow, he IS old...
If anyone knows plans for such a thing...
I miss my 65 Beetle. 6V system. Had to put in a 12V converter to get an 8-track to work. The car's horn wouldn't work unless I was doing 20mph or higher.
Even then, the 8-track wouldn't change tracks. I had to drill a hole, wire a pencil to the solenoid, and press it when I heard a thunk when it tried to change tracks.
The back seat was small...but service-able ;D
I went the back way through the army base and would have to speed up down a hill to skip over a small river to see my girlfriend.
I like to think I was more stupid then than now.
P.S. MPs are not your friend.
P.P.S I'm still kinda stupid. :lolb:
8 track was still state of the art when I was in high school. I can relate Zee. Fun times!!
Bill (oh and the count is 32 days now, but I'm still not counting)
The number of parts till that engine spins on air!Bill (oh and the count is 32 days now, but I'm still not counting)
Liar. ;D
I got to counting the number of lunches, the number of stop lights, the number of trips, the number of times I wore a certain pair of pants or shoes...
Yeah...I was ready.
The question now is...what am I counting? :thinking:
You made fast work of thosethree, er two pieces Zee. Not much left now. Should be running by the weekend if all goes well :)
Did they make the nut a left hand thread by chance?
Or is the toolpost bolted from underneath the cross slide?
I know you are a software engineer, but there should be an instruction book? :shrug:
So all the parts are done now....great!!!
Nice job on the eccentric followers. On that model the rods go through into the slot in the eccentric cams, right?
A liquid gasket does not require any punching of holes and you also don't need to make allowance for it's thickness during construction. When I do want a gasket that is what I use but often the metal to metal is good enough for air running and more.
Zee, Check the torque on the screws holding they cylinder onto the frame. If they are not evenly torqued the cylinder will cant and lock up the piston. It happened on my steam powered iPhone charger and I chased it for days before I figured out the problem.
Dont get frustrated, it will come together and you will learn a lot!
If it were me, I wouldn't try to run it in until it turns over smoothly, if a bit stiffly, by hand.
One possible way to power it for run-in would be a rubber wheel driven by an electric drill and held against the flywheel. Those expandable rubber cylinders used to hold sanding drums spring to mind, sans sand paper of course.
The question is...do I start a family war (mother-in-law) or not :thinking:
I've been posting my progress on facebook as well.
Got a response..."will it be useful or just fascinating?". :cussing: I get the same question from my mom. :cussing: :cussing:
So I said...something to the effect of...
"Fascinating IS useful. It can generate interest in others to learn about doing things with your hands, math (there's quite a bit), history (industrial revolution), art (there's a lot of creativity) much like things in a museum (whether models or not) that no longer do 'real' work. It takes you down many avenues of learning and interests."
I didn't say "what the hell do you mean 'just'" :cussing: :cussing:
I must have patience. She may simply have been asking if I had plans for it to do something like run a garden hydration system or stir kombucha.
Nah. She just didn't think further about what 'useful' means.
:lolb:
Well said Zee, my take on it, is that you need to do what makes you happy. In my case, if a project goes on for many years well so be it, I'm doing what makes me happy.

Zee, when you say the slides may be too high....what are we talking about here, .001" (which could still cause some binding) or something more...like .005" or more? If you lower the slides too much the hole the piston rod fits into may become out of line then. Just thinking out loud. Fixing one issue may cause another.
It seems the crosshead would be the easiest part to remake. I kind of doubt the cant theory too given how you machined things. If you shave off a small amount from the underside of the crosshead, it would do the same thing as lowering the slide a bit. If that frees things up then great. If t results in the crosshead being a bit loose in the slides you can reduce the height of the spacers to tighten things back up. That seems the easiest and safest route to me unless you find something else obviously out of whack :)

Working fine now!
have you tried flipping the crosshead over? Or as the other cylinder works how about using the cross head from that cylinder? MAKE SURE YOU MARK IT THE RIGHT WAY UP FIRST! Try the suspect one in the running cylinder.
Not convinced on the need for a DRO on the lathe but on the mill they absolutely transform the ease of machining parts - no more mental arithmetic or worry about backlash - I couldn't go back to a mill without one fitted now.
Do your tailstock up tighter, that will stop it slipping ;) make sure there is no dirt under the tailstock or a bit of paint. Also the "plate" that runs below the bed may have a burr. Also the nut under the plate may want tightening as you could be running out of movement on the levers cam
Back to the cross head issue , when making an engine I often turn a small point onto the piston rod and this can be used to mark the correct location for the hole in the crosshead
First side is looking good. Not that I’m really qualified, but, put on the optic visor and get eyeballs to eyeball with the other side and watch it with the patience of a world class chess player as you slowly turn it over by hand. With enough patience, I’d bet an RC Cola and a Moon Pie that you will see where it’s actually binding. Remember Caddy Shack? Be the engine 8) :facepalm:Good tip. Sometimes you can see the burnish marks where it sticks.
Cletus
I find that over time, the nut on the bottom of the clamping plate will loosen and I have to tighten it up to get a good lock with the cam
Awoke this morning to the second video of the ol' #7 running. Zee, I think it's running very well. As a matter of fact, if you don't have it anchored down, it isn't showing any signs of trying to "walk around", and that's great. Now, the question everyone here loves to ask: what's next? :stickpoke:Rhymes with zanly zeemer...
Cletus
Congratulations to you on a successful build, even if the success was not absolute (it never is...).
When it comes to what we do...we are our worse critics. Not a bad thing.
..it looks pretty good. But it's not a runner.
