Nock split
« on: November 20, 2018, 09:59:07 am »
I unbraced my bow last night and the string got hung up in the nock a bit. I looked closer and noticed that both sides were split and lifting. Before I thought to take pictures I glued them down with CA and filed the corners rounder thinking that is what caused it. Now I'm wondering. I tried to draw in what it used to look like. Do you think I've solved the problem? I may have to put an overlay on it to hide the splits >:( :-[

Mmmh, hard to say from the pics.
Is that a boo backed osage?
Have you upholstered the ears (in case you use FF)

Bind round just below the shoulders with sinew or linen thread which is then touched with low viscosity CA which will soak in producing a V strong fix.

Simon--It's boo backed yew. Upholstered the ears? I think I understand what you mean, like padding the shoulders but do you have a link to something that shows how it's done.
Del-- If I bind it, it will bridge over the string groove. Is that not an issue?

The sharp edges definitely have the string some splitting purchase.  I would overlay them.  Binding will interfere with your groove.

Sorry, I meant the string ears.
Good advice from Del and Pat above!

I do not like serving the loops, to much work for me. I just padd 2x2 pieces of Dacron at the ears.

I would overlay it regardless if you had those splits.  Bamboo will split easily when force is applied in the direction of the fibers.

I have just started doing that. I don't have any B-50 so I used extra FF. This string is 8 strands with no padding.

I'm thinkin' that's a plan. :D I just couldn't see this problem coming. I thought al the forces were in the right direction. I think I'll use some thin horn.

I'd superglue the cracks and add tip overlays

 Sure,  but it's made to take impact.  Whether on the head or the hoof.
