Square cylinder with round piston steam engine

[The_Paso_Kid]

This is an idea I had and decided to try it out using some square steel tubing as a cylinder and machining a round piston to fit into the square hole.

There are ports cut into the drive shaft which control the intake and exhaust cycles and the engine is capable of running in either direction.

Not actually unique PK, Elmer Verburg came up with that idea and made plans, #7 if the directory is correct.

Don't let that put you off though, what you are doing is using your brain and coming up with ideas, and that can't be a bad thing.

Keep it up.
