Okay So we don't stop a spinning piece on a rotating machine, I get that. Question what is a fellow supposed to do when hand sanding a turning bowl inside with his hand. Do we go buy a tool that does that for us? Do we wear a glove and take a chance there will be no catch. I think we can all say we have hand sanded a turning while spinning. Odie you welcome to chime in here with one of your gadgets.
