I am working on a number of platters. I was using my scraper in the middle of the bottom, completing the mortise. All of a sudden, my scraper snapped off about an inch back, just about where the tool sat on the rest. When I turned the lathe off, it looked like I had a catch. Tool height was right at center level. Anyone have any ideas? It's part of a HF set, and the wood is very hard and dense. Possibly the tool quality? I was happy the piece didn't fly off, but rather just landed on the bench.
