What was I doing wrong?
I did 2 passes with a 1/2" bit in this ash to get a 1/2" deep channel (don't know the correct term). No issues at all. But when I adjusted the fence to do more passes to make the width of the channel 11/16", the bit was pulling the wood agressively in to it and then broke. The channel was being widened on the fence side of the bit, and as I'm writing this, I think that was the issue. Am I correct? Almost had my second trip to the hospital thanks to the router
