ok,,,I may have missed some post, I admit I skimmed over it,, but,,, I think putting sinew on it would be a good idea,, it will give you practice at that skill, and it will add weight to the bow,, making the bow twice your draw would be a good start,, it may not be enough to hunt with but it will give you a good idea how sinew works,, just think of it as a learning experience and dont be so hard on yourself,,,you will get the hang of it as you go,,
