A couple of air powered engines.

I made these two air engines about 10 years ago, just to see if they'd work. They did so switched my attention to bigger things.

The first on was a single cylinder made of steel. I scratched my head for a while trying to come up with a valve that'd work. This valve system worked fine for air, but I don't think it would handle steam too well.

It worked on about 2-3 psi and up. After I made the single cylinder steel engine, I made a horizontally opposed twin cylinder with another two cylinders for valving, fed by small tubes.

Lost interest after that and took up building other things.
