I am working on an osage stave given to me by Hackbow and have a few questions, it has been taken down to one ring on the back and some wood has been taken off of the belly, but one limb tapers to the tip, where as the other limb barely tapers at all, so before I start floor tillering, can I cut one of the limbs down on the sides so that it looks even?, also, it has some bending in the limbs(not snake), it is not side to side but more backwards and fowards, should this be taken out before I start?, can they be left in?
