Thanks, Keefie. The info is helpful. I bet the spirals helped - at least until sanding time. I suspect I would run into more and more trouble as I approached the edge using my flat blades. I keep meaning to work with my spirals but I find that I want to make projects more than just do practice. Intellectually, I realize that learning to use the spiral blades would benefit me in the long run but I have trouble with the self discipline to just make myself do it. If I did, I could use flat blades in the center of a project like that and then switch to spirals as I neared the edge. It would at least eliminate some of the fuzzy problem.
Thanks for the info and, again, that is a sweet looking clock!
