neck sinew glue

Half an hour isn't long enough. At least 3 - 4 hours would have been better. My sinew glue get heated for more like 8 - 10 hours. After all it has to be composed of collagen surely?

My experience is different. After some minutes boiling of fish bladders they have nearly completely dissolved and the glue is sticking heavily between the fingers. I only boil it longer to thicken it.
Maybe sinew glue making is different, but I would expect at least a little stickiness after half an hour, there was absolutely nothing...

Yes indeed the bladders dissolve very quickly but sinew doesn't.

Just sturgeon bladder do that. Those kind of fish bladders are fantastic and different from any other.
Carp or other sweetwater fishbladder have to "boil" for hours as any other kind of glue like skin, sinew etc.
So if you like to make glue than have to boil tham more for better results.

Like a good meet-bone soup :) Long and low heat boiling.

Not only sturgeon, as I use croaker bladders ...

Tried to make glue from backstrap sinew yesterday and after half an hour it gave at least a little sticky feeling, rubbing between fingers, but was much too thin to use.

So I boiled it for 4 hours and the resulting glue seems to be good. What astonishes me is that it gels very slowly. I had expected it to gel fast...

Ok
..most of the bladders ... :)

I don't know it. Thats a sea fish?

It?s a sea fish, yes. The type of bladder used by Korean bowmakers.

I made another try on my scrap sinew leftovers (cow backstrap), which I cooked for nearly 6 hours on low heat. The bonding capacity of the glue seems as good as that of my fish bladder glue, and some commercial hide glues I tested (including rabbit glue). For testing I used two square hickory sticks about 10 cm long, diameter about 12mm, glued together longitudinally. I wasn?t able to break the resulting glue bond on all samples with my hands. Interesting result: When the gluing surface was smooth it could be broken (this happened on the first samples with the sinew glue). A little scratching and the glue bond is strengthened considerably...

Hello JJ! About neck sinew! You can use it for glue it is for shure only material is very hard to desolve . I cook my glues in low temperatures and using this stuff is very time consuming but however it produces pretty strong glue . For me this stuff is most hard desolving material. I use only deer or moose. I tried to cook it from wild boar (becouse I have lots of them here as most popular hunting game) but it can take much more time than from moos or dear or roe buck - day and somethimes more. Frankly everything has made from wild boar (male at list 3 years old) are abnormally resistant I recommend using backstraps .
About fish glue! Good source of raw material is Pike bladder - it is a comon fish in europe so thats the reason why I use them ( they have long type of bladders) . I dont know why but the sinew glue mixed with pike bladders I found very elastic and strong - but it is only my experience and observations.
