Having trouble choosing a glue... epoxy or CA - any ideas?

Hmmm, having a hard time visualizing this. Can you perforate the side, thread the wire through, and pin it? sounds like it’s be visible, hmm. Can you split the drop spindle, anchor the wire with a cross pin, then glue it back up? I’m just not sure I’d trust any glue to this application. I may be misunderstanding it, though. Good luck!

One on the left has a wire hook, while some use a simple cup hook – I am trying to avoid a cup hook because I think that the find threads in a cup hook would not last long in end grain.

Why don’t you rough up the end of the wire that goes into the hole? Give the epoxy something to “grab”.

You say the threads won’t last long in end grain, but as an alternate you are trying to use a smooth wire that has no threads at all?
Before I saw your image I was thinking a solution might be to add threads to the wire.

But -

I’d go for the cup hook, make the hole bigger and fill it with epoxy, then embed the threads in the epoxy.

It is sometimes useful to clean the threads really well with lacquer thinner and/or acetone to be sure the epoxy bonds to the metal.
You can increase the torque capacity of the assembly by filing a flat or notch in the threads before embedding in the epoxy.

CA glue is available in 3 different viscosities: thin, medium and thick. I would try a thick CA glue for this application. It is much easier to work with than epoxy and it has equal, or superior, holding power.

You have the option of applying an accelerator to CA glue that will cause it to set up almost instantly. You might almost fill the hole with CA glue and spray the accelerator onto the wire. Then insert it quickly.

Cyanoacrylate glue is not what I would use. It’s brittle and hard
to get to do what you want in real load-bearing circumstances.

An anaerobic-curing type super glue may be a better choice. I’ve
fooled with the stuff a bit and the kit I had came with a bottle
of very fine power… maybe glass. You could fill a hole with the
powder, saturate it with the liquid glue, and it would harden
into one mass.

“The Last Glue” is one such type. Neat to have on hand anyway,
if a bit pricey for experimenting on one project.

In defense of G2, one of the best epoxies out there, My guess is that you tried to mix a very small amount. It’s very hard to get proportions accurate at volumes less than a couple of ounces and the smaller the amount mixed, the more critical the mixing ratio. It would have hardened like a rock and you would easily twist off the wire before you broke the glue to wire joint if it were properly mixed and cured.

Generally speaking epoxy is best for jobs large enough to justify mixing at least 1 1/2 to 2 ounces.

Very good to know that about epoxy – I was indeed mixing small amounts, perhaps 1/4 of an ounce.

What is the best way to mix epoxy? 1:1 ratios I find easy, the 2:1 of G2 epoxy is more difficult. I was using a small plastic medicine cup with 2 cc graduations. Anyone use some other way?

You could use a small gram scale.
Also, you could always use a toothpick to get the epoxy in the hole.

I just did a three part (so far) blog on epoxy use, mixing etc. http://lumberjocks.com/shipwright/blog/series/4499
It should help you understand some of this.

Different epoxies have different ratios and different tolerances for poor mixing but in small quantities like 1/4 oz it would be very easy to be way off ratio and end up, as you did, with a mix that never achieves any of it’s true characteristics.

I read your blogs Paul, very good info.

Thanks NiteWalker – I have a scale that reads to 0.1g accuracy, so I think I will try weighing my next mix. I see that on the product specs that the weight mixing ratio is slightly different than the volume ratio – http://www.systemthree.com/reslibrary/tds/G2_TDS.pdf

i’ll throw my two pennies out there, but this only applies if you are not going for looks in the final outcome, but if it was hidden and/or cleaned up good i think you will be alright as the finished dried bonding has a light gray color to it, that being said, i have had good outcomes using the “quick jb weld” for a variety of bonding different materials together… thats all i got

?well did you find a solution that worked.
