So i tallied up the votes aaaand....
4 folks said its either doomed or toast(5 if ya include me, and 6 for someone else i know that hasnt said anything public about it...yet)
2 said a sinew patch might get ya by for a little while
And only 1 said that sinew will give you a better chance at success than rawhide,but i didnt get the impression he was telling you thats what you should do to this piece of wood. ..
So..basically no one told you that you should sinew it,but yet thats what your gonna do???
Why ask for help,and then not listen to the collective voice of experience?
Learn to tiller WELL,and be able to hit weight consistently before getting into the time consumption of sinew backing.
Me...id burn it and not waste my time...you can try a sinew patch and wrap over that and itll give ya a quick little "feel" of how to and learn to work with sinew...but i still WOOD NOT put that in the hands of anyone else let alone a child...who knows how deep that rot goes,and it looks like a ticking time bomb to me and it def has a short expiration date on it. Set it aside,burn it,or experiment with patching,but get a better piece of wood to learn on. Your already severly handicapped never making a "bow" yet and trying to learn on iffy wood makes it even worse...and LOTS more frustrating trying to learn. You want success asap otherwise youll get sick of it and stop trying. Learn on better wood
