Title: Best Horn Overlay Glue
Post by: PAHunter on April 30, 2014, 12:06:14 am
I'm using horn overlays for the first time and one popped off twice already with super glue.  Any suggestions on glue or method are appreciated!

All I use is loctight pro super glue, how good do the pieces fit, got to be a perfect fit, I start shaping my tips half an hour after I glue them on and none have come off

I use loctite gel super glue. It sucks that it only comes in the little squeeze tubes. But it seems to work for me. I use it for overlays and elb horn nocks. Make sure both mating areas are good and flat. Use a perfectly flat sanding block or a disc sander with a table. Check with a ruler if you have to to make sure they are perfectly flat. Wipe they off clean with a damp rag, apply glue, and stick together. I start working them pretty much instantly, it takes about 30 seconds to glue.

I've been using gorilla glue.  I'll use Loctite next time and put more time into ensuring the surfaces are perfectly flat.  I've done wood overlays many times with TB without any issues at all.  Thanks for the advice!

Unless you are useing gorilla super glue the original gorilla glue expands and I wouldn't use it on bows at all

Just a thought, but I've used horn nocks several times and what I do is make sure the surfaces are flat-tight fitting and clean! Then I wipe both down with acetone, just in case of oils in the wood or horn and use loctite gel.

I used to use superglue, and yes I was using industrial grade glue, until I have a couple failures.  I've found that superglue get quite brittle when it hardens and when you have high string tension brittle is not what you want so I switched TB3, going on quite a few years now.  TB3 gets really hard but it doesn't get brittle and once I switched I stopped having failures.

I use superglue all the time. No prob.
What wood are you using? It looks like ipé? If so, clean that thoroughly before applying the glue. I use denatured alcohol myself with ipé.
Also, your overlay design is not particularly resistant to shear. The overlay is short and the wood belly is not sanded to an angle. This increases the shear forces.

I also go with Loctite gel. Get the fit tight. Clean the surface. I clamp them on with a spring clamp and start working them within a half hour if I want. Never had a pop off.

I also use Titebond III and have not had any problems. I'll also recommend sanding the wood so the overlay sits on the stave at an angle, and as many before have said make sure the surfaces are smooth and thoroughly degreased.
