I was taking a final light trim cut on the inside of the bowl to just smooth it out before sanding and it went bang! I know I did not cut through the side and the tool was not removing much wood. I was using a Ci0 Easy Finisher when this happened and I did not feel it catch. Any thoughts on what would cause this? This particular bowl blank did fly off the lathe one time a few weeks ago when my son was visiting and wanted to try turning...since I am a newbie at this it was the blind leading the blind. I did not make a very good lip for the chuck and he had a minor catch while removing material and the bowl flew off and bounced around. Luckily neither of these incidents caused and bodily injuries:embaresse:embaresse
