Jamie per your question about the mass. looking at the tiller on that bow it is bends through the handle with the outer limbs a little on the stiffer side. You selected a good width for your handle and center of bow area. Because of the stiffer outer limbs I would have fed in a higher number for draw length, this is all explained in the chapter. You came in at 15 oz and the target mass would have been around 12 oz. I can't see how you tapered the belly on your outer limbs but I suspect you tapered them in thickness rather than width, Rounding the belly on the last 1/2 of the limb and side tapering would have likely brought you right into mass. If the outer limbs are bending less than the inner limb but not as thick you have extra mass out there, if they are the same thickness they would idieally bend the same as the inner. I like to think of the thickness as telling us how far the wood can bend and the width controlling how far it will bend under strain. When thinner area of the limbs are bending less than thicker areas we have a little misplaced mass on the bow. Still a good job. Steve
