See? This is why we wear protective equipment when woodworking.
I was within minutes of being finished with this piece. I had increased the RPM's to apply the final burnishing (see the nice shine on that broken piece?) when suddenly I heard cracking noises. I had just enough time to knee the kill switch and step back. Boom! and it split down the middle. If you look at the piece still hanging from the chuck, you can see bark wood along the broken edge. That particular flaw was not visible until the bowl exploded. Crap!
At least I didn't get hit this time, the flying pieces went the other way. Left a dandy dent in the dust hood you can see just behind the broken pieces.
