Thread: A different kind of engine---

IT RUNS!!! IT RUNS!!! My God---its setting beside me right now, running like a ---well---like a steam engine!!!! I got the steam port machined and drilled this afternoon, and took apart an old mechanical pencil for the spring that holds the brass cylinder block tight against the side of the main frame. I ran up to the hardware store and got a peice of 1/8" i.d. polyurethane tubing and machined a small coupler and silver soldered it into an air chuck fitting. I tried it at a real low air pressure, and it wanted to run, but there was just a bit too much friction. I kept turning up the air pressure, and flicking the flywheel, and finally it started to run all on its own. I immediately had to call my wife down to the workshop to have a look, and then my next door neighbour!!! After it ran for about 10 minutes, it must have worn down some of the friction points, because I was able to turn down the air pressure significantly. I am totally stoked!!!
