I've had a couple of bowls recently that were finished drying, and since the rims were nearest the pith (but didn't include the pith, of course) there were the usual peaks in the rims. One of them, I needed to take off a half-inch+, and the wall thickness was a half-inch, so I wasn't sure the best way to take that off. Actually ended up scoring a line with a parting tool, and then using a little saw-knife and then thin-kerf saw (lathe off) to cut through it. Is there a better, more kind-to-the-hands way to do this?
