I have experimented a little with tip designs........ My bows in question are hickory and osage 66-68" t/t for a 28" draw and 1 3/8 inch at the fades tapered to 1 1/4 inch 8 inches from the tips. From there tapered to 3/8 to 7/16 inch tips. I also like just a slightly flipped tip, seems to shoot well.
Boo backed Yew RD. Limbs are 1 1/8" tapering to 1/2" at the base of the recurve
Don, I see that bow turned out fast. Do you think your limb profile design you are getting good results with in a BBY can be utilized just as well in a self bow? Would you try it without the backing?
I've never been able to get a selfbow to hold the reflex. I did try a very reflexed natural branch that I spliced into an RD. It had no recurves. It was not that fast, 180's I think.
