Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

Well, I got my glass tubing finally and the bending went much easier than I expected. So now it's time to fire it up for the first time.
Actually i think I'll try it on compressed air first, since I expect a few leaks. Since this is a museum piece I expect to get it running in full steam mode but will probably hook it up to air for the museum. Then folks can see it run right away.
What kind of pressure do these thing run at? Will one of those little aquarium pumps run it?
