Several years back some fellows on the MEM forum created a Corliss engine. Although much simplified as far as the valve gear it still uses the same type of valving and mechanisms.
Not wanting to follow the herd I opted to scale it down so I took the smallest bolt on the original and scaled it until a M1.0 x .25 could be used. The scale factor came out to .40 of the original. Most of the bolts were .125 or 5-40 so these scaled to M1.2 x .25.
It's primarily made from steel with some store bought stainless bolts, the rest being home made.

Just magnificent! I can't begin to imagine how to make something that small, let alone anywhere near that level of precision and beauty...
 
It's beautiful and it runs well. I have been reading your posts, but I wasn't really thinking it would be done already.

Well Done.

Thank You for all your posts.

I wanted to build a governor for the engine, not to control anything but just for visual appeal. I looked at pictures of the Coles Corliss to get an idea of the proportions and drew one up. I machined the miter gears. They came out to about 72 P.D. I had to take everything back off of the base so that I could drill the mounting holes for the governor. What a pain taking apart all those tiny nuts and bolts. I didn't want to buff the aluminum base but I used very fine crocus cloth the aluminum polish. It came out shiny but not mirror like, which is what I wanted.
