They don't all work out. Here is a nice 8" pecan bowl that turned into a failure, and a valuable lesson. It was the largest object I've turned, and it roughed out nicely. I was starting to make finishing cuts to clean up the outside, and things went terribly wrong. I have heard it is best to try new techniques on practice pieces... but at this point, almost everything is a new technique. This was a very dramatic "catch" of my skew chisel. It broke out a big chunk of the bowl, split the bowl in half (you can see the glue line if you look for it), and broke the chisel in half as well, sending it across the shop banging against the opposite wall. I didn't get hurt, so I'm happy with the outcome! Just lost a $50 chisel and a $15 bowl blank. Some lessons cost more than others.
