In reading Rudy's books I notice that he runs his stationary engines off compressed air. I dont think he shows a boiler in use for any of them. Can any one tell me how much air psi to use on the engines. I understand that one would just gradualy increase psi until things are running ok. He mentions 3-5 psi in one artical concerning his radial five.
Thanks lee

Most stationary engines require very little pressure to operate. When I plumb my dad's tiny power to the compressor I always have the valve pretty well down there. It's finally full open if I let the air get down to 10 PSI or so. With the smaller ones even less. If you have a small compressor that puts out 25 PSI or more you should able to handle anything in the stationary world that's not huge. Even our 1 1/2" Chloe locomotive will run on its treadmill with as little as 10 pounds. when it's not pulling anything it only has its internal friction to deal with, and since the engine is built accurately that's been minimized. www.youtube.com/watch?v=vYLooaqocmM

You can run smaller engines on a large aquarium pump - this can be a simpler and quieter way to show the engines than a regular air compressor.

Lee,
You're going to find that the answer to your question depends largely on how well built the engine is. I'll also point out that even the best built engine will probably be a bit "tight" at first and require more pressure than after it's broken in for a few hours.
I had the pleasure of meeting Rudy in person and seeing many of his engines running up close and personal. I can tell you that they were superbly crafted and ran very smoothly. It was very obvious that Rudy was quite the craftsman and a very skilled machinist indeed.
