Thank you Gary.
Yea, some one else asked me about the finish too. It must be the florescent lighting in my shop ceiling. I need to start using some other lighting in another area of my shop. The mill has a white shop light above it and there are a couple more of the same type of lighting over a couple of benches in my shop. Or maybe it's a setting on my camera? I should check that too.

Thank you Bill.
Yes, I enjoy working with a solid modeling program and figuring out how to set up the model in the cam program and machining it using CNC.

This the last update on this build.
I made the remaining parts, pins, vent, steam connection and pre assembled the engine. Put air to it and I'll be darned but it runs! I had lubed the parts as I was assembling with air motor oil. I let run for about 5 minutes at around 20 - 30 psi and eventually it would slow down and stop. It was getting more and more stiff and hung up so I decided to dissemble to see if maybe a pin had come loose or something. Every thing looked OK except for a lot of fine and chunks of brass and metal shavings through out the crankcase.
I then cleaned all the parts thoroughly with lacquer thinner, finished polishing and painting.
I reassembled using white lithium grease. Especially around the oil grooves on the pistons.
After assembly I noticed that the whole mechanism moved quite easily and freely with very little "notchy-ness" in it, hooked up the air hose and it runs nicely I am surprised to say! The engine runs great on around 5psi.
I was really worried that I would have problems but it went well.
Here is a link to the video, I'll post over at the Finished Projects forum as well.
Thanks for following along,
Gerry
