That's ok, thanks. I was out in the shop to do something else just now, and I went through the old flywheels again. As it turned out, one of them had the right taper, but it was a little too thick. Out came the hole saw and I cut the center out of the flywheel. A few minutes on the belt sander and I had it down to the right thickness as well. Done deal and works perfect. On with the rest of the project. (It's a Great Planes Fokker Dr1 triplane with a Kioritz 23.6cc, and it's looking like it's going to turn out great!)

I'll get a machining book or two and get the lathe set up some day soon... I've used a lathe several times for basic operations, but nothing very advanced.

Take care,
