Red Oak Pyramid Bow

Step 8: Attach the nock wedges

I liked the nock wedges over cut nocks on narrow limbs like these, so being chicken, I spot glued the nocks an inch and a quarter from each end, lashed with hemp twine and soaked with titebond glue. and they still moved when I first strung the bow!!! Fortunately just a 1/16 and symmetrically so I didn;t have to fix it, but that gives you an idea of the forces involved here.

The added weight to the tips of this bow (nock wedges over cut nocks ), it is said to affect the performance (less arrow speed)
Have you notice anything like that?

not to shure of gorila glues effects on wood

Gorilla glue is polyurethane based and cures chemically with moisture.
The instructions say to wipe a damp cloth on the wood before applying.
It doesn't take much and the moisture is used up in the chemical reaction.
Poly glue also expands as it cures forcing it's way into the porous wood.
You did clamp it well right?
Regular wood glue contains water so that has to dry out too.
Waterproof properties are a moot point since getting the wood wet will weaken and bend the wood long before the glue fails.
So it's really up to you what to use.

Would artificial sinew be a good choice for lashing the nock wedges? I have a bunch left over from my kayak, I think.

No, artificial sinew is usually polyester of nylon, bit stretch a lot, that would be bad.

what is another type of glue other then Titebond that will work?

[Tool Using Animal]

Any waterproof non brittle glue of decent shear strength.

super glue, bad choice.

Most yellow wood glues ok
hide glue ok
gorilla glue ok
epoxy excellent

instead of hemp cord use rawhide cord, gorila glue ends of cord to bow-maybe-
(wet rawhide cord will titen(cant spell) as it dries)

I'm personally not a Gorilla Glue fan, if you check out my crossbow instructable, you'll find a much more attractive way to attach them.
