Ok, think I have finished the tillering, made a 2nd string, 1st was 1" short. Added string to bow, measured between string and handle, 6.5". Note, had cut walnut off handle and added a scrap piece of cedar and reshaped, much better. Tried to check draw weight but my digital scale keeps stopping if I don't push fast, best I got was 31lbs and 23", was shooting for 35 to 40 at 28". Will have to take to local bow shop and see if they will check it for me. Question: how thick should the bow be around the nock area and last 8 inches leading into it? Backing is burlap (see pic) seems to work great but when I add finish to bow, should I add to backing also? Using polyurethane. see attached pictures.
