Shop made mini steam/air engine. mrpete222/Tubalcaine is a youtube machinist-shop teacher. He went to an auction and ended up with a tiny shop-built wobbler type steam engine that was in a jar. He dubbed it the "mayonnaise engine" and proceeded to make several videos showing how to make one. I made this from those videos. You will need your own mayonnaise or pickle jar haha. Made from steel, brass, and copper. The one I'm offering does not have an exhaust pipe, just a port which is more like the ones Mr Pete made. It is quite heavy for its tiny size and runs very well on just a few psi of air pressure. Great conversation piece, fidget spinner, paper weight, etc. You can see it running here, copy and paste the address of course.
