I would decide what style bow you want. Reduce it to near finished, a little heavy so it's not too light after tillering. Make sure and leave extra wood around that knot. Floor tiller a little. Then steam or dry heat the bent limb so the tips line up with the handle center. Put a little shellac on the back of the part to be steamed to prevent little cracks from rapid moisture loss. I've made great bows from backs with these little cracks, but better not to have them.
