On my last wood purchasing expedition (Hi my name is Brian, and I have a wood collecting problem). I (SWMBO really) got several platter blanks. I have never turned a platter, and am thinking that I could have a real chatter problem when the platter gets near final thickness. How do I avoid the chatter near the outside of the platter when cutting. With a finial, I cut the thin end, and work toward the thicker end. With a larger diameter bowl, the procedure is essentially the same, working from finished outer edge toward the center. Is the procedure similar with a platter, where I would essentially finish cut the outer edge of the platter, while there is still some beef toward the center, and then start working toward the center, or is it better to fashion some sort of steady to give support behind the area being cut? 2 out of 3 of the blanks are dry, and one is very expensive camphor burl that I really don't want to screw up.
