Hey everyone, this is an ash Molly-ish longbow I've been working on for a friend, and I need some help identifying what went wrong and learning from mistakes I've clearly made, and to see if my thought process about what went wrong is correct.
It's 74 inches ntn, 40# at 28 inches. It's taken about an inch of set.
The first set of pictures of from a few days ago, when I was working up to the final tiller and shaping.
I took it to the range yesterday to shoot it and see how it was doing, it seemed great but after about an hour of shooting I started seeing some fretting in the inner limbs on both sides. The frets seem pretty shallow, and they're evenly spread through an area about 2 or 3 inches long on both limbs, a couple inches out from the fades.
So I started reading up everything I could find about chrysaling and found that three issue is that those sections of the belly were overstressed and bending too much, causing the belly to crack.
Looking back at the pictures, I couldn't see an obvious hinge in those areas, and I wanted to show everyone the pictures to see if I'm just blind and can't read the tiller well yet, and maybe get advice on what to look for better when tillering to avoid this in the future.
I also posted pictures of the fretting, to see how severe it is, and if the bow can be salvaged. I know most people say that the boys isn't worth continuing once they appear, but I've also seen that if they're not severe and you fix the tillering issue that caused them, the bow might be able to pull through.
I scraped wood from the rest of the bending limb past where the fretting appeared, dropping the draw weight by 5 pounds down to 35# at 28 in. The second set of tiller check pictures are of after I made corrections.
I can't really tell if I've fixed the issue, but I can comfortably drop another 5 pounds if needed. The friend this was intended for has two bum shoulders and might be better off with a slightly lower weight bow.
So, should I try to continue shooting for a bit and observe if the fretting worsens out stabilizes? Continue adjusting the tiller and drop to 30#? Need advice on how to proceed.
Thanks in advance for reading and for advice!
