beautiful engine down to the last detail1 i am curious if you have cnc machines or old school? I don't think i could do the engraving with my equipment, although i must admit, i wouldn't have a clue how to program a cnc machine either. What did you change in the design to make it for compressed air?
Incredible work and detail.

Thanks guys for all the nice replies !
I have a Tormach mill which I used for some of the parts and the engraving. The bulk of the parts were done on manual mill and lathe.
I eliminated the feed water pump and changed the oiling piping. The cross head tube is without the large side opening that would have been used for driving the pump.
I plan on being at NAMES in April and will display the engine there.
