Did you ever get this one running? Any specs on performance?
No, I didn't build this one, since I built the prototype Fo Mi Chin II on which it is based. The Fo Mi Chin was run successfully by Bruno at Burning Grape, and he called it a very "sweet running" engine. That's as good as it gets for "performance figures" on that one. This one is my re-design for those who don't want to hassle with welding onto a shaving cream can. It is as close to identical to the prototype in terms of internal dimensions as I can get it, so there should be no reason to doubt that it will run well.
Go for it!
And where do you buy that antenna tubing?
Try Menards, Home Depot, Porter's Do-It Store, etc. It is painted a sort of bronze or "antique gold" kind of color, and comes in 5 ft and 8 ft lengths, I believe. However, you have to waste about 5-6 inches of each end. It costs around a dollar a foot. It is mild steel, well under 1 mm in thickness, with a welded seam. It cuts like cardboard with a good hacksaw and welds very nicely using mild steel rod.
