I attended Craig Kirks presentation at Tahoe and finally got around to trying the technique. I thought I'd start with something simple like this bowl rim to try it out. One thing I did differently is cut the convex portion on a bandsaw, not a router, and fine tuned the cut on the disk sander, using similiar jigs with an adjustable pivot point. Probably took longer but worked for me, at least for this project. Bowl is 10 1/4 " by 2 1/4", black walnut and maple. As with others, a big thank you to Craig for his creative development of the jigs that make this style possible. I hope to apply this technique to something a little different in the future. We'll see. C & C welcome and encouraged.
