Also have another idea I'd like you guys to kick around. I've been toying with the idea of building my first biplane. Any good bi-plane should have a round fuse, of course. Want to use the regular white foam we use for the So plane for that. So, how to do it? I'm thinking I could heat up a metal ring of some type held in a vise with a propane torch. Then take a piece of foam that has already been cut into a long rectangle that is slighly larger than the diameter of the ring and simply slide it through the ring to cut it into a round shape, or cylinder more precisely. Ideas? Thoughts? Put Downs?
