tip overlays slipping

[AH]

ugh....I'm working on a bow that's got cocobolo tip overlays and they keep slipping. I've tried titebond, superglue, and epoxy, and it still slips. Any suggestions?

If the surfaces are straight and clean id say try superglue again,but with light preassure and not too much glue

[Mark Smeltzer]

Super glue will normally seal the oils found in wood like that. I've used it to seal an entire riser before I applied the final finish. Maybe try scrubbing it wit some acetone or something?

And then reapply the super glue.

How's your wood to wood surfaces?

Right or wrong, I always use titebond 3 and have never had one fail.

Is the problem that the glue won't set? Like a chemical reaction with the cocobolo? I heard of folks sealing the cocobolo with super glue first then gluing the overlay to the tip.
How are you clamping the overlay?

I use loc-Tite gel super glue. Works everytime.

Is it slipping when you clamp it, I use loctight pro super glue, don't clamp it or anything, just squeeze for a few seconds , no fails

[mikekeswick]

The problem you've got now is that the woods pores are filled with remnants of the glues you've used. You need to completely redress the mating surfaces and use a quality superglue. If you are having problems with two wedges slipping apart cut your self a strip of inner tube  about 1/2 inch wide. This will clamp them perfectly.

Only time I had this happen was two part epoxy failing to cure properly. Purely down to it being far too cold and damp.
I took it inside where it was warm and dry and it cured fine.

By slipping do you mean they slide when you try to clamp?  Many will use rubber bands or simply hold while the CA superglues takes set.

If they are sliding after drying, that's a problem with the glue not drying, like a chemical reaction as already mentioned..

Happened to me once on a 3D shoot. My mates teased me and said I should fix it with a six inch nai .
I took their advice, but did it a little more elegantly with a silver nail.

Loctite Professional in the blue bottle. It doesn't come "un-done"......ever.

I never worked with cocobolo but yes I do have suggestions.But I may have. Don't remember.

Lightly sand the area to get rid of old glues. Make certain the wood surface contact is impeccable. Get some acetone (nail polish remover) and wipe both surfaces liberally.

Sizing first is a good idea. I would try a good waterproof wood glue like Titebond 3. Apply liberally and clamp. Sometimes the overlay moves as you clamp. All you need is a light pressure.

Follow the directions on the label regarding application and type of surface required. Some glues like a rough surface while others require a smooth one.
