Title: Glue tests
Post by: PatM on April 06, 2012, 11:16:46 am
Here's an interesting link to some glue tests that I foiund while researching a type of liquid hide glue that I've just become aware of.

So the toughest glue on planet earth was the weakest.

Thanks for the link.  I'll have to show this to the wife.  I had her pick me up some TB3 and she wanted to get me some cheap wood glue.  She wanted to know what the difference was.

    That's a good article for most people's applications, but I'd like to see it expanded to include flexing wood as in a bow. This may sound nitpicking, but I think it could make a big difference.

Rob, I was thinking the same thing. A flexing joint is way different than a static joint. Some glues will easily flex with the joint and maintain their hold but others may not.

I disagree. A good glue joint is a good glue joint.  This test really just confirms what bowmakers already know by practical testing.

I also make bamboo fly rods. All of them were glued with gorilla glue and they are all working as well today as they did the day I finished them. I am fairly certain that my rods bend more than my bows.

The point being, ALL the glues are plenty strong for just about anything we are going to use them for.

I use and recommend Titebond II or III for my Reparrows. I have tried Gorilla Glue with poor results. Quick setting epoxy works, but is too much trouble and isn't any better.
