I am about to tiller a yew/sinew short bow. I messed up the sinewing process and the sinew is wrinkly. I want to cover the sinew with birch bark and I have a number of questions. First off, do I need to smooth off the sinew and should I do this before I tiller - I am guessing its a yes to both those questions. Once the bow is tillered, how do I go about covering it - any good build-alongs on PA or on tinternet ?
Thanks in advance,
Andrew
