Hey I bid on that one too! I have fixed many bows worse than this and I believe this should go back together perfectly. I’d mask it off and use a thin epoxy like the West System 105 resin with 206 hardener because it will saturate every little crack and void. I usually apply the epoxy, wait 30 or so minutes, then re-apply I wouldn’t even waste any time on dowels or pins. The repair should be completely invisible and result in a nice shooter!
