This bow came from a side split of Osage. I worked it just enough to get the exterior wood off. It turned out to be 48 @27. 66ttt Them I decided to back it with something that I had plenty of and that was turkey feathers. I started at the tips and selected two feathers from the neck area, then I selected two more the same size from a little further down the neck, so on and so forth. Then at the grip I used two golden/copper tipped feathers from the tail. I used lin seed oil for the finish( I need to buy tru oil). It is a crappy sewing job but it holds the leather together. it takes 1 1/2 after un-bracing. This is my go two bow now.
