The microwave technique works great. I've used it a lot when I'm turning bowls. Too bad they don't make a microwave long enough to get a bow stave in!
Luke, I'm a novice at this bowyer stuff, so I can't offer you any advice. But I do appreciate all your talent, and want you to know I learn things from every one of your posts. Keep at it. I'm really interested in how it finally turns out.
