Danny, I believe a lot of set comes early in the tillering process, especially for most beginners. I am bad for overstressing a bow while I build them because I get rushed. Patience is one of your best tools in wood bow making!!! Try not to pull it past the ultimate draw weight at any time while you built your bow. Also, exercise it between wood removal, even if it is only a few inches. I usually exercise it by pulling 20 to 30 times. While you are building a bow(or anytime with a wood bow) you should not hold it long. What I do is stand back and pull it a little on the tiller tree and look at each limb, relax it and mark the stiff spot(and possible hinges) and pull it again and look for another, etc. Pat
