NOMADIC PIRATE:
Change of direction ;D, just got some words of a bowyer that uses TB III for sinewing his bows and gets excellent results,.....guess I'm back leaning into the TB III option ;D
Marc St Louis:
Regardless of what some people might say you won't get the same results with TB3 as you would with hide glue but it will work ok as long as you introduce some reflex before you apply the sinew. Even though the sinew is encased with TB3 it will still be affected by moisture and consequently lose cast. You will basically get the same moisture proofing with hide glue if you use a good finish and maintain it, the key word here is "good" finish.

With Marc on this....bob
Justin Snyder:
I'm with Bob and Marc on this one. I have been doing a lot of reading about animal glues, and here is my thinking. Because hide glue gels before it dries, if forms one continuous layer with the sinew. As tight bond dries, it will honeycomb, leaving tiny pockets of air in the glue. When the hide glue is put under stress it will stretch because it is one continuous piece with sinew reinforcing. The TB will be hundreds of individual pieces of sinew kind of linked with glue. The other benefit of hide glue is that it glues when it gels. This means you don't need to hold it in place as long as synthetics. Because it is gelled, not dry, the last piece will stick with the same strength as the first. You could wait until the TB is tacky, but that means partially dry, and the next piece will not stick to it with the same strength. When an additional layer of sinew is added, the hide glue actually reconstitutes, and the new sinew becomes part of the original layer, not a new layer. Do not use the liquid hide glue. It gives away one of the great benefits of hide glue of gluing when it gels. I thought it might help make the decision easier, or harder, but more informed. Justin

Hmmm, leaning towards hide/knox .....again ;D ;D
