Working steam engine single action

Simple project I wanted to do. I figured if anyone is looking to make a cool project like this it could help. You'll need to sand some things down like the sliding valve to make sure it slides well, but other than that once its together it will run. You will need to adjust the timing, which is easy to do. I would recommend putting some oil in the cylinder, it makes it run a bit better. I used compressed air.
Thanks for your interest.
