Title: Would you attempt this fix?
Post by: JJACOBS on August 18, 2013, 03:05:00 PM
This happened a few months back during the season when I was practicing my draw technique. This bow is composed of fiberglass over carbon on the back and hickory-fiberglass on the belly.  All that happened was the fiberglass seperated from the carbon when I drew it.  It did not explode so I slowly let down and unstrung it to find this. Question is: is this a foolish battle to fix or is there some method that may save this bow?  Running super glue inside and clamping to down is what I was thinking may work.

How close are you to Tupelo. I have a bud that has repaired a couple for me.

I am along way from there. About 2-3 hours

if i were to repair it i would use smooth-on and a heat lamp. mix up a little bit and smear it in and clamp

Yep - Smooth-on.
That job is a bit beyond super glue.

I'm with them...Smooth on is the only way to go.

I am beginning to suspect that it was a dry glue joint.  Anyone have any ideas on if that is what happened?

If I had to guess, the bow was most likely exposed to some heat in its life time, such as in a hot car or stored to close to some kind of heat source maybe? Also may have got some dust in there during the gluing process.

The dust is possible, the heat is not, it has been stored inside since I made it last summer.  Anyone else wanna chime in on ideas of fixing it. As of now I am leaning toward smooth on as suggested

If I were going to fix that bow I would use a heatgun and try to remove the glass alll the way to the tip. Then use Smooth-on to re-glue the glass. If you have the form, I would put it back in the form and put it in the heatbox. Maybe some of the guys that use a lot of carbon will have better suggestions.

I'm with James on this one-

James, that's an interesting idea, how would that work with the limb tip overlays.  Just remove them with it?

when you put the smooth-on in --force it back in the tight spot with fine monofilament
I did one with clear glass and watched it fill in the void--by the way the bow still shoots
good luck-----

You had this same thing happen bamboo?  That's a really innovative idea

I do agree with JamesV suggestion.  Otherwise you run the risk of not getting the epoxy into all of the areas needed.  The downside is that your lams may not separate cleanly and/or splinter as you try to get them apart.  However, if you would thin the smooth-on with heat, place it in a syringe and then force the warm epoxy in all of the areas, it might just do the trick and I am more likely to try this trick first.
