Hi all I know this is going to cause some controversy so here is goes. I help out teaching woodturning and this year we had a student get nicked up because of hitting the edge of the chuck jaws twice. We all know to stay behind the tool rest and away from the chuck but it did/does happen. I thought about this and thought why now put a piece of rubber around it? I went to the local bike shop for old inner tubes and they had a 28x3.5 tube which was perfect to cut into about 1 inch strips circles like rubberbands and put over the edge. At least if you happened to hit the edge it might keep you from getting nicked. So comments/suggestions/concerns?
