Gluing Sinew

<< < (6/6)

NOMADIC PIRATE:
nice Thread, I'm getting my first attempt at sinew backd bow ready, I'll use TB III because of the reasons Pat mentioned, the stave has 2 1/2" of natural reflex, I'll temper a bix of extra curve on the outher limbs before glueing the sinew on, can't wait to see how it turns out :)

If you want to stay primative , and retain the benifits of the combo of hide glue and sinew,while becoming almost water proof. Replace the hide glue with fish bladder glue (it is much more water resistant) and cover the sinew with snake skins . Then seal the bow with your favorite finish .

I've had bows like this out in the rain with only animal fat finishes.I oil 'em up good before leaving the house and they do just fine.

I have heard about fish bladder glue. Is the making process basically the same than in hide glue? if not then how do you make it? and what fishes have the best bladders?

Trapper:
Hi guys , after reading all the responces I will tell the secret , the titebond Liquid Hide glue is hide glue no two ways about it , And to make your liquid hideglue reconstitute itself is by adding just a little vinegar to it , if it strings out between your finger and thumb then its still Ok but if it dosnt then its went past the shelf life that it has, but the vinegar thingy works to fix it , Ive never had problems with sinew raising on me or anything , the only thing you have to do is waterproof it after it has dried, Polyurathane spray works exellent.And the next important thing is be sure your sinew has been soaked in water , I like to soak mine for at least 24 hrs, you would be suprised at how much fat is on top of the water after this and you thought you had it clean.    Dont ever add bleach to your sinew water , it will make Ramen noodles out of it , and they will never be strait again.  Trapper

What I know about fish swim bladder glue.
The Turks used sturgeon.
The Koreans used a puffer fish ,I think.

Isenglass is fish bladder glue ,you can buy it from beer and wine making supply companies ,they use it clarify the wine or beer.
You can also buy it from paint supply companies ,Art restoration people people use isenglass as a medium for oil paint.
And oriental food markets sell it under the name 'fish maw' make sure you get dried fish maw instead of the puffed fish maw.The puffed fish maw is deep fried fish bladder.It's used to make soup.

You make fish bladder glue from swim bladders ,it's the same process as hide glue.As far as I know any swim bladder will do.
