I have some delamination of the fiberglass on one of my bows. I'd like to keep this bow as a usable bow. Now, modern fiberglass laminate bows are out of my relm of knowledge as far as making and repairs other than a few things here and there.
I need help to repair this issue, so if you have had this happen and repaired it with success please help.
Sending it back to the bowyer is not something I want to do just yet do to the very high cost of shipping.
It is a hill style bow and the delamination occurred on the back starting at the fades into the handle on the lower limb. (https://scontent.fsnc1-1.fna.fbcdn.net/t31.0-8/fr/cp0/e15/q65/13925485_1231826396830071_6006068313893810353_o.jpg?efg=eyJpIjoidCJ9)

My first concern is if rhe glue on the rest of the laminations is still good.
For fibreglass I would use smooth on glue. Could,use a very thin spatula etc to get it liberally inside. Then moderate clamping.
As long as the ambient temp. Is 80 degrees it should not,need a heat box.
Shipping in the USA priority would be about the same as the cost of the smooth on glue.

Thank you very much. Side note, it would be shipped to England.
Btw, it's Myrtle limbs and cherry handle and 120# @ 30"

Wow some heavy duty stuff.
Big difference on shipping.
Be nice if you could find a bowyer in your local area that might already have glue.

I would cut the stitching on that grip ----if that paper slides to there I would assume its delammed further
--also when you get the glue under the glass----thread some monofilament fishing line under the glass and while sawing and sliding you can force the glue all the way to the furthest limits of the damage-then yank the line out-I fixed one delammed from the tip to just passed the fade and its still shooting after ten years--so there is hope!!
good luck!!

Since the separation is at the fade I suspect some flex is happening at the fade that the bond failed due to stress, especially when considering the high draw weight. I would contact the bowyer, it may be more cost effective for them to replace it than attempt a repair.

I wonder how thick the glass alone is? 120# limbs and .030 or .040 glass could be a recipe for a de lam. Not sure though. Just intuition kicking in.

I don't think I'd shoot a delaminated bow with a "lets stick some glue in there and see what happens" kind of fix, especially one of that weight. If it was a bow of my make and I didn't want to just make a new one, I'd at least peel the glass off the rest of the way and then put it back in a matching form with smooth-on and new glass, then trim, sand, check tiller, and refinish. But glass, glue, and making a new form will likely cost more than sending it back. That's assuming they would do under warranty. If not, probably better to find a state side bowyer to fix for you.

Just out of interest who made that for you?
