Hinged Limb Help

[EnglishRedneck]

Got a glass/boo bow that is developing a hinge near the riser. Still zaps 'em, but I'm getting concerned. Would you hang it up, patch it, shoot on regardless, what? Will get pics when I can, but in the meantime, please tell me know what you know abpout hinges...

Thanks

did you leave strung up in your car or anything like that? a small amount of heat on fiberglass bow will allow the epoxy to creep a bit. still the pics will help.

On selfbows a hinge must be corrected or they will break sooner or later.
I've never heard of one on a fiberglass backed bow, maybe Bob will come along and advise.

Buy a new one from Bob thats your best deal in the long run!!!

I've never heard of a laminated glass bow doing that. The only way it could do that is if it was delaminating so there wouldn't be a hinge but for a second or two.

I kave heard of this problem on glass backed bamboo bows several times. The compression on the bamboo from the glass is too strong. Bamboo works well on the back or tension side of the bow but not well under compression.

This concerns me. In my experience, which is considerable but not shotproff, a hinge is a sign of glue failure. I would keep shooting it but squint my eyes. Just be carefull.

OK, Hinge turned out to be a glue failure. The reason it didn't just delaminate, is that I ahd wrapped the limb in Carbon Fiber tubing (bit like you see on braided brake lines, but cf not steel). I figured this would give me an extra margin of safety on a home-built bow and it did. The problem is the Bowgrip 100. I followed the instructions perfectly, cooked it at 185 for 8 hours, toothed everything correctly etc etc, and had glue failures in 2 places.

Anyone want to trade some Bowgrip 100 for some Smooth-on?

If this is a solid wood bow as I am assuming. Try urac 185 . That is what all the wood bow guru's claim as the best...
