Help with fiberglass bow problem????

[warden415]

I am making a fiberglass laminated bow. While feathering out the limb tip overlay, I ground pretty far into the fiberglass on the back of the bow right where the limb tip overlay meets the fiberglass. I was using and air grinder with a round sanding drum. I just got in a hurry and dug too deep, I think I had the grinder at a slight angle. I would post a pic but I don't think it would show much. It is .050 glass and I dug through about .030 on one edge and deeper as it runs across the glass, on the other side maybe through .040? So I am left with only .010 on one edge and maybe .020 on the other. THe divet is basically a hollowed out spot.
  I cut the string grooves and the bow is done except final sanding and finish. I strung it up and have shot it several times. My question is how concerned should I be about the bow letting loose and breaking at that point where it is so thin?  I would suspect this will be the weakest point but I have left it strung for a few days and I can't detect and obvious distortion in the profile of the limb other than the obvious divet across the glass. Any help or ideas appreciated. Steve

warden,grind the tip overlay off and put a longer one on to overlap the grind spot , make sure you have plenty of glue in the dip and you will be all right, the tip don,t have as much stress as you would think, good luck

I'm just guessing, but shaft slinger's advice sounds logical to me.  I think I'd want longer reinforcements and the divot filled with epoxy if it was mine.  I guess I'd also add the longer reinforcement to the other tip also, just for symmetry.

I would cut the limb a 1" shorter on each limb and put new tips on it. depending on how short the bow is already. It will gain 6 to 8 lbs depending on limb design and reflex.
