First r/d has compresion fractures help

(1/3) > >>

Jesse:
OK. after about 120 more shots a problem has shown up. Compresion fractures on both limbs the entire length. They are barely visible and the bows performance is still right on the money but I don't know for how long. I was thinking about sanding the belly flat and gluing on a thin fiberglass lam. Any thoughts on that? The bow is the one I just made and had posted. Its boo backed ipe 55# @ 27 " The boo was too thick I think. The bow may also be too thin 1 1/4 at widest evenly tapered to 1/2 inch at the tips. This bow shoots awesome and I put a lot of time into it. I really want to save it. Any suggestions? You can see them in the right light . not cracks but the wood has slight bumps on the surface now I can feel them a little bit if I run my finger over them.

Badger:
Your demensions are good, if it is showing compression fractures in one area of the limb you just had that area working a bit too much, very easy to do on a r/d design. Depending on the length of the bow I would consider getting the other areas of the limb bending a bit more and if you have to shorten it a tad go for it if it is long enough. Steve

Jbell:
Hmmm, that is strange, does'nt look like like chrysals. I went back and looked at your full draw pic and if any thing your not bending to much in the pic your showing us, so if what you are showing us is the begininnings of compression fractures your boo must be way to thick. How thick is it? If you think it is to thick then I suppose the solution would be to sand the belly flat and trap the back of the boo. I would'nt do the fiberglass thing, if you trap the boo and sand ridges out and lose alot of draw weight you could turn this into a tri-lam and glue up another thin piece of IPE. Good luck, someone else may have a better suggestion than mine, I have made quite a few boo backed bow but not with IPE and had a problem with a chrysal in black walnut once but that was because of a hinge.

Jesse:
here is a pic. of the area with the most noticeable problem. I didn't realize the ipe would get so thin.

Badger:
If it is too narrow in that spot in can still get compression fractures without looking like it is bending all that much. Probably could have just spread the bend out a little more. I t may hold up fine just like it is, I have had several bows with shallow compression fractures that held up for a long time. Steve
