I'm working on a maple bowl, about 15x6. I did my rough turning to about 1 inch thickness several months ago using a large recess to chuck it. I now have rechucked it in that recess and discovered some modest warping. Using my bowl gouge, I've pretty much restored the roundness to the exterior, but am unable to get it uniformly smooth. The end grain portions are really rough ... and the same goes for the interior. I've tried the lightest of cuts, to no avail. Before I get out my 60 grit sandpaper, any suggestions?
