Thanks everyone, and thanks for the advice Keenan. I'll keep scraping away then. That was my instinct about the knots, I just needed some reassurance I guess. I'm excited to see this bow turn out. my dad arrives in oregon in a couple weeks, I might even have it ready for him.
I'm thinking about trying my hand at tip overlays on this bow. I picked up a scrap piece of ebony at the woodworking shop yesterday. has anyone used it before? is it a suitable wood for an overlay?
