Thats ok....It still works great.  I think that a better way to say it though is to say that it has bone in it.....that I will believe.

Either way you look at it its a great glue. I use it a lot. I am not a spokesmen for Knox so could really care less what you all use. I will keep using it because I like it.

Knox works great. Hide glue works great. Home-brew hide glue works great. The point is- no matter which is what, they all work. I haven't made a lot of sinewed bows, but I have sinewed three bows with Knox over the years and didn't have any problems. I sinewed one bow with homemade hide glue and didn't have any problems. Hide glue maybe has more mojo, but it's all good.Go forth and sinew.

Knox is bone glue NOT hide glue. Ifn ya wanna use semantics here ta say it has bone glue in it thats fine with me. Like you dont care what foks use. This is not the same as the white wood wars. White wood there was being said as good as osage and disputed  by the osage foks. There is no dispute here, the facts are out in the open fer all ta see. Knox is bone glue period its NOT hide glue as I said. That bein' said "keep on keepin' on "  and "whatever floats yer boat ." No axe ta grind here.........bob

I dont think so....

Opening question of the thred:

"I have done a search on hide glue on this page, and my head hurts.  Should I just use Knox for sinewing my bow?  Or should I go buy a 1/2 pound from a music instrument place like frets.com?  "

You can look at the title of the thred all you want. I am answering the question posted. And now I remeber why I have not been posting here  :-\

ok then to answer the original question .

   Hide glue is sold by the manufacturer (can't name them ) by it's strength measured in jelly grams .Weaker glue is cheaper .The weakest glue they sell is listed at 80 jelly grams ,the strongest at 512 jelly grams .I have no idea if anyone lists the jelly gram numbers for knox , but I do know archery supply places don't post the batch strength of the glue they resell .

This leads me to believe most suppliers carry glue much closer to the 80 jelly gram rating ,than the much higher 512 jelly gram rating .This could easily explain knox's current good reputation as glue. I have bought the 512 jelly gram glue direct myself (he told me he sold very little of it) and it is much stronger than most hide glue I've used .The batch of 512 jelly gram glue I got is very close to well made ,homemade hide glue ,and will crackle glass.

Well, since I was the thread starter, let me explain my wants.  I wanted to basically know about sinewing and what to use.  I am a newbie.  And knox is obviously a choice for some.  So I appreciate the info on all of it.  Even TB3.   But the idea of using TB3 doens't make sense to me.  I thought the idea was to use a protien animal glue with a protein animal product and they would meld into a beatiuful good back of a bow. And add wieght.

Thanks for all's contribution.  They are all appreciated.

Knox claims a gel strength around 350 grams, but it does weaken as it dries. Hide glue is usually about 20% higher dried than as a gel.  Hide glue purchased for woodworking averages around 250. That explains the tests in TBB I.  If you make your own from hide you can get more strength.   You can make liquid hide glue by adding urea to warm hide glue.  The shelf life of liquid hide glue is about 6 months. After that the urea starts to degrade the glue.

bigcountry, I would take AKAPK up on the hide offer if I were you.  You can even grind the dried chunks of hide and they dissolve faster.

I do like a good heated discussion, you cant buy knox over here so I dont have to worry about it, I'm about to try some fish bladder glue that I  just made my self!!  never used any animal glues so far , so wish me luck!! my plan is to do away with chemicals  alltogether,

by  the way I believe hide glue will be stronger than knox if it's made well, and of a higher grade ,

you can only buy one grade of hide glue here as well , which I believe is graded at 80 (80 what  I dont know) , is this strong enough to gue backings on or should I make my own? and if I make my own how do I know what grade it is ???
