    Default Stabilizing a crack

    While preparing for my Cougar lll Elite cam change, I found that I've got a crack at the bottom of the cam fork, about 5/8" long, on the front side ( target side ) of my 5H 08 carbon limb. I say 08 because it was a bottom limb and has the sticker on it, ser# 08. Since its going to be a nitrous shoot thru bow, Im wondering if I can stabilize the crack/splinter by gently sperading it open and letting an epoxy ooze into it and then clamping it togather again. I can see movement with a magnifing glass while twisting the forks, but those forks won't be twisting any longer. Tell me what you think. What type of epoxy or super glue would work best.

    I definitely would get those limbs replaced.

    BTW the target side is the back of the bow...more for enlightenment and not criticism.

    you got a good picture of it and the responces we knew already.

    it was a used bow when he got it. any other ides on a fix, it is only a small crack..Bow will be set up X system, no torque on limbs.. We would like to swap it out for a new one, but no warrenty on a used bow..

    So lets all think out side the box a minute.. Any one Ever try to fix something like this?

    Never tried, but thought about it and never heard of any attempts. No torque is definitely a plus, so the only way to find out is to give it a go using the strongest epoxy available. You will need to apply heat and that needs to be done carefully so as to not weaken existing lamination joints. Also, after glueing the crack, some glass matting could possibly be used to strengthen the area.

    Have you priced a new set of limbs, I don't think they would be much over $150.

    Good luck.

    It more splinter than crack, doen't carry through the limb, just that surface. I just knew someone would catch me with which is the front of a bow! Can't slip nuthin past you guys.

    It's likely one lamination that's cracked.
