Title: Small Crack, Big Problem?
Post by: BeauxGeaver on May 24, 2020, 10:33:05 PM

Hey everyone!
This is my first post on here, but not my first time in archery. My dad was a regular on here back in 2007 but he fell out of the hobby soon after. I devided to get back in the hobby since I was a small boy then.

In 2007 my dad did a bow trade and he got a osage orange bamboo backed R/D bow. A few months later we noticed a crack in the limb. Flashforward 13 years later, i want to use that bow and remembered the crack. Now i want to make sure the bow won't break on me. I was thinking I could use strong fishing wire wrap with an epoxy just as insurance but i wanted to open it up to you guys.

What do you guys think?
Thanks,
--Beaux

P.S. Let me know if you need more pictures. The crack is in pic #3

I'm not sure I can see the crack very well.

Hard to see.  Is it that little thing across the limb?  Almost looks like a tool mark.

looks like the belly has developed a compresssion fracture.
Is there a hinge in that spot?

That's what I was thinking, Dor. Also looks like it lifted a grain flame on the belly leading to the fret on the side of the limb into the belly. If it is in fact a fret I'd say the bow is now a wall hanger.

Several of my bows have developed that type of crack after many years of use and an estimated over 250K shots through them. I tried to wrap the cracks and save the bows for the owners, it was all in vain, the bows failed

Thanks for all your replies,

I tried stringing it up with a string an inch longer than it normally would use and i also tested it with just the stringer. Heard no cracking and saw no additional movement. I even shot it to see if there was any strange sounds and there was nothing. Going to keep it strung up for a bit and see if there is any difference. I'll also see if i can find a shorter string that will fit that bow. One thing that i noticed is that it is at the exact spot as one of the thicker areas of the bamboo backing (see picture for example). Not sure if that changes anything.

The nodes can over power the belly depending on the wood type.
