diagnose this failure... a fix?

[Roy from Pa]

On the edge like that, yes CA, patch, and a wrap.

[Bowjunkie]

You could try the Torges patch.

First though, I would put thin CA down in there and clamp that glue joint back together. After it was dried, and THAT part was effectively repaired, I'd grind out the area where the grain seperated with a sanding drum of sufficient radius to remove that crack and as much of the surrounding 'strange grain' as possible. Don't grind all the way across the belly if you don't have to. I've had excellent results with those patches... but should admit that I've never had to take one as close to the backing as the glue joint, and yours has already seperated a little there, so I'll be waiting to see how she holds up if you try.

[Echatham]

yeah i might as well try.

[John Scifres]

I think a wrap will hold it down.  I've had worse ones survive.

[Eric Krewson]

Spread the crack if you can, fill with super glue, clamp, give it a super glue soaked thread wrap and you will be good to go.

I use nylon string serving thread and serve the bow just like I would serve a bow string.

 

Out at least a half a dozen such wraps, the only one I have had fail was one I served up to a bamboo node but not over it and the node failed. If I had served another half inch the patch would have held.

Eric it looks like your were patching a problem on the back... but it should work just as well on the belly  right?

[fujimo]

absolutely- probably better chance of survival on the belly, as they are very effective on the backs anyway.
i do as Eric does- serving thread and CA. looks neat, and pretty tough.

[Echatham]

seems simpler, and i don't have a drum sander, just a bench top belt sander that i was going to use the end of.  gonna give this a try when i get home this afternoon.

[Eric Krewson]

Belly cracks are an easy fix. I fixed a belly crack like yours for a friend 3 years go. He has shot the heck out of the bow since, even finished second in the IBO worlds with the repaired bow this year. These thread wraps really hold up well.

[Eric Krewson]

Here is a monster Torges patch I did on a a friend's narrow bamboo backed osage ELB a couple of weeks ago to fix a rotten, very cracked knot. So far so good, I used a half round file to cut the bad place out.

   

[Echatham]

 

Well we will see tomorrow if it will hold

[fujimo]

looking really good- i am sure it will be just fine!
g'luck

[Roy from Pa]

That looks fine and it should hold, Eric. If you want, you could do a similar wrap on the other limb to match it for cosmetic reasons:)

[PEARL DRUMS]

Roybert is hardcore into cosmetics. Like Mary Kay, Avon and all the other high quality types.

[Roy from Pa]

Hey Pearly Boy, I hain't sent ya that bow blank yet:) Watch your potty mouth son.. LOL

[Echatham]

yeah i thought about that... and i might.

[Echatham]

put about 50 shots through it today... finally... seems to be holding good.  thanks for the tips guys.
