Well the bad news is that it snapped on the back side while I was tillering. This was my second bow, almost had it done too. There was a knot in the middle of one of the limbs and that's where it snapped. No worries though, these sort of things are going to happen.
The good news is this was another satisfying learning experience for me.
Thanks for the info, I'll keep in mind about the heat treating if I come across another one.
