Hi all! This is my third bow, but my first attempt at sinew backing so I have a few questions. I started tillering the bow today and when I reached around 20" of draw I noticed some "popping or ticking" from the limb. It seems that I read somewhere that this is normal while tillering a sinew backed bow but im not sure! Also I was wondering what would be a safe draw length for this bow Its 54" long, 1 7/8" at the fades, 1 5/8" mid limb, 5/8"at the nocks. Thanks for any help! Scott
