sinew moisture resistance
JackCrafty:
Funny, all this talk about making sinew moisture resistant. Just about anything that forms a barrier between the sinew and the atmosphere will make it "resistant". I've never heard of tannin doing the job, though. Sounds interesting but I wouldn't put money on it. ;)
Ed Scott makes his sinew backings waterproof by applying the sinew with waterproof Titebond instead of hide glue. This technique is controversial but I thought I would bring it up... heheh
I've used titebond to glue down sinew wrappings and it repels water nicely. The only problem is that you have to destroy the sinew if you want to remove it and re-wrap.
BowEd:
My viewpoint on using titebond with sinew is that you would have to reverse brace it for sure to have the sinew work more.I'm sure it would add a certain amount of poundage to the bow and protect it.Hide glue is the only glue I know of that shrinks the most when drying thus enhancing the performance of the sinew.If I wanted to just protect a back on a bow I'd just put deer hide on it.I've never personally used titebond with sinew and would love to hear of someone who has used both hide glue and titebond on different bows.Just like I'd like to hear if someone has used tannin in their water with the hide glue.
BowEd:
At this time I'm pretty certain tannin in the hide glue would do nothing more than cure the sinew like it does with vegetable tanned leather.The jury is still out as to the amount of moisture resistance it would do for the sinew.
