Working on my first osage bow, going for 62" ntn, 1-3/8" wide for 1/2 limb tapering to 3/8" at nocks. I have worked back to single ring and roughed out shape and think I should be able to get 60#s out of it at 26". I split a 1" wide x 62" piece off stave when roughing bow out. Would I be able to get a 35-40# bow out of this scrap and am I on right track with 60# (I hope) bow.
