bd,my son in law's bow is 1 1/4" at the widest point,and tapers evenly to 3/8" tips.But,it's only tillered to 25". I'm sure osage would handle the 29" draw,but ,it will set quite a bit. If your just starting out,I would build one a little longer ,say a little over 60".It'll still be very manageable to hunt with,but a whole lot more limb to bend,as your getting the feel of tillering.Just my 2 cents. Check out George's site as mentioned above,it'll help you get going. God Bless
