This is a steam engine that requires no machining of parts, and everything you need you can buy at a hardware store. I made two of these about 2 years ago but I didn’t take any pictures of the build. So this is my third one, I built it this morning.
What you will need:
½ brass test plug .625” O.D.(piston) http://www.grainger.com/Grainger/Rod-Stock-2ABJ4?Pid=search
½ copper repair coupling 12” stick (cylinder and other components)
½ copper pipe.
½ copper cap 2 Qty
¼ copper line
Wood for a base
3/16 brass rod (connecting rod)
5/16 bolt and Nut to fit
3/16 steel rod
Caster wheel (flywheel)
Miscellaneous hardware as needed
Step 1: Base and Flywheel Stand
2) Now you need to pull the caster wheel out of its bracket assembly. you don’t have to cut a relief in the base for the flywheel to sit beyond flush, I just like it because it keeps the center of gravity low.
3) Cut out two posts from the ½ copper pipe for the fly wheel stand. Drill two pilot holes in the post (leave under size, will ream full size once post are cured to the base)
4) Drill two 5/8 holes in base for flywheel stand.
5) Mix two part epoxy and bond the post to the base, put a rod through the pilot holes and make sure rod is set perpendicular to the base as the epoxy cures.
