Does it have a fretboard attached above it? Titebond or epoxy would probably work a bit better than a "stick" wood glue. You want a liquid glue that will penetrate every wood crevice, and you'll want to clamp it up as tight as possible. You could bore a coupla long wood screws, one going each way, penetrating the joint. If it's fretless, you could always wrap some duct tape around the joint for a more "homemade" look...Best not to leave it in the trunk in the heat again.

yes better glue and possibly 1/8 or 3/16 holes through the joint with wood dowels glued into it...

Here is what I read about Evo-Stick, "general bonding of wood assemblies for non-structural applications". A scarf joint is quite the structural application. Use a better glue and some screws or small dowel like the others said. Oily is probably onto something with the heat too.

Titebond III is the best glue, but i would avoid complicated jobs like scarf joints ... (-:

      Just do a pocket peg head. Their the number one way I do my peg heads. No cutting or gluing involved. Plus it`s super strong !

I use my dremel router base, 1/8" deep cut out, a little deeper under the string retainer. But I have done them free hand already also.

If the glue is this stuff, it's a liquid resin glue that's extremely strong if used properly.  It's what I use and I've never had an adhesive failure.  You need a close-fitting joint with a decent surface area. You also need to clamp it together for at least 12 hours, and leave it longer to get full strength. Maybe try a test piece with 2 scraps of wood of the same area as your scarf joint.  Let the glue set for at least 24 hours and then try to pull the joint apart - see which breaks, the wood or the adhesive.

Oh, and use plenty of adhesive - the surplus will run out of the joint when you clamp it up and you can tidy it up when it's dry.

Yep thats the stuff.

I think the problem is the contact area might be too small. Having said that I had it strung for about 3 days at tension with no problems until I left it in the boot of my car.....im hoping it was the temperature.

My main problem is this guitar was ready to go....going into an exhibition this Thursday...completely finished, varnished etc. Ive re-glued and will try it again tomorrow. Problem is of I cant get as tight a fit as was there before unfortunately.

Thanks lads for the advice.
