tear under recurve
« on: December 09, 2019, 09:05:43 pm »
Hi everyone. I was just putting a bit more recurve into a bow that I had already steamed curves into and then tempered. I thought I could get away with just using the heat gun rather than steaming and re-tempering but I put a small tear into the belly side of the curve. I'm reluctant to cut out the 2" to remove the tear as the bow is black walnut and 63"ntn. I'm concerned that 61" is a little short for a black walnut #40, but it is 1 3/4" wide for much of the working limbs. Can I just fill the crack with epoxy? It's a static recurve so that area is not bending. The crack goes about 1/4 way through the depth of the curve. Thoughts?

Patching these type of cracks is easily done by reducing past the crack and adding on a matched piece.

Usually I fill with super glue. Usually I have some wood I can still remove from belly side. I let the super glue cure good and then I file down. If it's not bending and remains that way, it shouldn't be a structural problem. More of a cosmetic thing. If you don't like it you can put a underlay on later. Maybe see if your Black Walnut makes it.

I've had this happen on a couple of occasions and dealt with it like BJ suggested, super glue and over(under) lays for support.

Properly installed underlays and overlays can repair anything.

If you chase a ring on the bellyside, get them soaked for a few days first then boil them - you won't have this problem in the first place.
