Rodger's Marshall's air engine
Rodger Marshall sent me some video of his air engine, based on my plans.He used it to power a chain transmission, calculated using my gear template generator.

I used the gear generator I got from you to make a chain and sprocket and drive gear. I realized that the engine would turn it too fast, so I made a gear and pinion to reduce the speed 4 to 1. The drive belt is a rubber band. I think it still runs too fast so I am in the process of making an air flow control valve that hopefully will be able to adjust the speed. Attached is a short video of my results so far. Thanks for making the plans and software available. Rodger Marshall
