The osage stave I let cure for about 10 months and then started working it, This was the first stave ive tried and the reason I backed it with sinew was becuz I noticed a few checks in the back of the bow. Im not happy with the sinew job could of been alot better but a real good shooter. also theres the first board bow I built, its red oak backed with hickory, its also a good shooter. hope you like the vid
