A friend of mine had a nice white oak board with very few run off's. The moisture content was 12%. Trying to get it about 10% before tillering it. I am going to try and make a 72" bow that is 1-1/2", 6" stiff handle, pyramid limb to 3/8" tips. Shooting for 45-50# @ 28'. Never made one out of White Oak. Does the white oak need backed with hickory, or could a guy get by without backing, or at least burlap backing? Thanks
