very strong glue

[kid bow]

i need to know if anyone knows of a very strong glue i can use to glue components together for an experiment and it requires an extremely strong glue

[Weylin]

Hide glue is the strongest that I know of, it just isn't water resistant.

[kid bow]

it needs to be heavily glued and backed so im asking if anyone knows of a very strong glue

[Weylin]

Well, different kinds of glue are better suited to different kinds of jobs. what exactly are you trying to glue?

splices on a handle

Depends on what you are gluing.  Traditional hide glues are the strongest in the world.  Modern science hasn't been able to best it.  What it has done is make it more convienenty to store, make it water proof etc.  But those things come at a cost of strnegth.

Epoxies can be super strong.  Look into "G2 Epoxy"

I like URAC-185 but it isn't made any more.  I just glued up a bow with "Weldwood plastic wood filler" which seems comprable to Urac only less expensive and no shelf life.

Tight Bond 3 is hard to beat if the surfaces are well matched.

thank you

Where does this idea that traditional hide glue is the strongest come from? Hide glue IS very strong and versatile and it really is the best for sinew but there are plenty of stronger and even more versatile glues out there.
 You are probably going to have to go with what you can get. I would recommend DP 460 from 3M but you might not be able to get it and it is extremely expensive.
 The G2 is likely more readily available. T-88 from the same manufacturer is also outstanding.

I have used Urac, it is good glue, but messy as hell. I prefer 2-ton Devcon epoxy slow set (30 minute set)....the quick set is crap.

i thank you guys for the help on this. since 2 of my favorite bows broke im trying to splice components from each together. so like recurve tips and a handle riser

I saw some tests done with Knoxx hide glue one time. The guy running the test mixed the glue up in a corning wear ceramic bowl. He didnt use all the glue and it set up in the bowl on him. When it did, as it dried it contracted and ripped chunks of cermaic up off the bottom of the bowl.  I was amazed to see the pictures and read his article.

Hide glue has the advantage of being water soluble so that the parts can be soaked in water and taken apart.  Other than that, hide glue does not have any advantages over epoxy's or other modern glues.

For the strongest bonding of wood with the most economical glue, use a slow set, 2-part epoxy and follow the directions to the letter.

[PatM]

That perceived greater strength of hide glue when it pulls stuff apart is because of its ability to shrink, not so much because it has greater holding power in peel/shear etc.
 If you put two blobs of good Epoxy on a ceramic bowl and had something spanning them that could be tightened like a turnbuckle the epoxy would also pull the coating off the bowl as well.
 Good hide glue has an elastic property to it though, that is  likely unmatched by modern glues.

The mechanical design of the joint is as important as the glue...
I know, I just had a handle splice fail on me
But I fixed it

Nelson has replaced Urac-185 with Unibond 800 which is probably the same thing with a different name. I would choose this new glue over any of the standard epoxies.
