I can't find any good reason this thing broke.I've pushed wood very hard before with no problems,and yes it was very clean,and had a beautiful near circular tiller.The whole limb,(working area),was sharing the bend,and there was no torque in the area ,and I was at the point of long stroking it to finish up.I'm in east Texas,so the stave being too dry really is not a possibility.There had never been any heat applied to the area either.It's just like someone told me once."It's just a piece of wood".I guess that's how I'll have to take it. God Bless
