Beautiful parts Brian!  :ThumbsUp: :ThumbsUp: :ThumbsUp:
What do I see there, a thrust bearing? You are going all out on this one!  :LickLips:

Very short post on some pre-assembly work ...........

With the cylinder and frame being made from aluminum the two rubbing together would not be real good. Especially without means of lubrication.
I purchased some adhesive backed UHMW tape that is .007" thick and applied it to the cylinder for a bearing to the frame. Very easy to do with a sharp Xacto knife.
Trimmed to size after applying including the air ports.
 
More to come ..........

That should work well. It's a great wear material and should last a long while unless the engine is run a lot.

Assembly of the piston pivot ......

Thought I'd try something new with this engine pivot. Added a small thrust bearing for the spring to ride against. This provides the tension to pull the cylinder against the frame and eliminates the spring twisting during cylinder motion.
Added a brass sleeve to center the spring on the shaft and a split shaft collar to adjust tensions.

That is a clever idea and should work well on an engine this size. Might be a bit harder on an Elmer's sized wobbler but fits right in on your engine  :ThumbsUp:

Final assembly and pictures ...........

Made a brass cap for the pivot assembly and assembled the crank shaft and flywheel. Did not like the painted base and took everything apart and finished the base with a fine glass bead finish. Made some spacers that go on the crank between the crank throw and the flywheel. They rest against the ball bearings and keep the crank in position.

Added a wood base and name tag to finish the build.

What a nice runner Brian!!  Can you comment on the engraving you did on each face of the cylinder. It looks nice, just curious as to how you did that.

Nice job! Quite beautiful.

I had noticed the engraving on the cylinders too and would like to know more.
Very nice touch!  :ThumbsUp:

Hi Bill and Zee,

The micrometer is kind of my logo and it is a scaled up drawing I did years ago based on a Starrett 0-1/2" micrometer. I drew it actual size and scale it to fit whatever I would like to use it on.
The engraving is done on my Tormach 1100 using a diamond drag engraving tool. I've done some engravings of this mike smaller then 1/2" over all size with good detail.

Works great in brass. Here's one done on anodized aluminum engraving stock.

Thanks for the comments !
Are either of you going to NAMES ?

Can't make it to NAMES. A bit too far.
It's on my bucket list. Might take a road trip sometime.
