Delamination

[briandean]

Another question:
Is it possible to repair a limb that has started delaminating?

I had an air bubble under clear glass over Zebra wood about 6 inches from the tip. I used my electric heat gun and a putty knife to seperate the glass from the lam, then reglued the glass and clamped the limb without reheating the bow. Could not even tell there was a problem afterwards and the bow shoots and looks great.

Good idea JamesV!  The real issue is to make sure you never have a delam again....  What I started doing is applying the epoxy with a gloved finger.  This way I can feel that the lams are getting a good thick coat.  I also let the coat sink in for about a minute before I go on to the next lam.  I used to apply the Epoxy with a wooden spatula like Bingham’s video showed me years ago when I started.  I had a few delam spots on this limbs.  Since the new way of doing it with my finger I have limbs approaching 6 yrs old and thousands of shoots with no issues in any of them.  A word of warning always where a rubber glove if you do this because if you run a bare finger over ruffed up fiberglass you will run small splinters in yourself!  You will also need to mix double the amount of epoxy and yes it will squeeze out a ton as you apply the pressure.  I would much rather waist an extra $5 worth of glue than ruin a $100 set of limbs....

Thanks for the advice :-)

I had a Mojostik delam on me. At least 3in's all the way across the belly. I used a small piece of wood to hold the lams open. Mixed 2-ton epoxy thinned with acetone & applied it with a syringe. clamped it for 24 hrs. Still holding very nicely.

My brothers recurve dalaminated in the top limb recurve section. we pulled the lams apart, mixed epoxy and warmed it up until it was thin like water. now we applied it to the limb, and tightened it with inner tubes. now its stable again.
