Thanks John. I just spent a week in the hospital so I hope I am not answering your reply too late.
Couple things I learned about this spiraling tool in the short time I have used it John. One is that the guy who told you soft wood doesn't work well, is right. Another is that the speed seems to influence the quality of the cut considerably. That gavel handle I posted is very small so I cranked up the speed to 2000 rpm's. I think the most important thing I learned was, make one pass across and go to the right a little ways, then slow down etc. I think I was holding the handle of the tool too low, so I raised the handle while turning and the quality of cut was much better.
Quick question John, if you don't mind? You ever make many Chalices? I got cornered into turning one for our priest, who wants to use it while celebrating mass, and have several questions and your the guy who would know. Mitch
