Very weird....I'm building my first electric guitar, but I've been working with wood for a long time. I'm putting a 1/4 sapele face on the back and for some reason I'm having trouble gluing the book-matched pieces together. I've always used Titebond, but for some reason the joint won't hold and I can actually just pull the two pieces apart after letting it dry for about 24 hours. Has anyone else had this issue? Any suggestions? Thanks!

How old is your Titebond?

That is a good question. Probably less than 8 months old. It's Titebond II and it's been working fine on maple.

Sapele is usually not a problem to glue.....try cleaning your freshly joined edges with some DA prior to glue up. Perhaps this piece has a high resin content, that should take care of that.

Silly question, Brian: What is DA? I'll be needing some for gluing Teak soon, I'm sure, if it helps with high resin/oil content.

Cheers,
Nick

Denatured Alcohol.

Thanks, Brian that is a good idea. I will try that and re-post.

I knew it was a silly question. What's 2+2 again? :)

No silly questions! Just don't drink the DA!

Not even with a mixer? :)

There are no silly questions...just silly assumptions.

When joining Sapele I only use Titebond and have never had problems.

I can only think of two things...bad glue...or contaminated surfaces.

Third attempt on this glue up. Re-jointed, wiped down with DA, and tight clamps. Just a little bit better but still able to bend the joint. I think it's time to give up on this billet! I'm pissed that I already planned to add the thickness on the back and planed down my mahogany body. Now I need to find a maple cap for the back.

Next time only try to use Titebond I, with the red label. The other one should have held, but you probably didn't have a clean joint and not enough surface to glue. I know titebond II is not recommended by all the luthiers I have ever seen talk about it.

I agree, titebond 1 is preferred for this game. But I have glued more Sapele than I can remember with the type 2 without any problems.

Thank you JEguitars and everyone else. I re-jointed AGAIN and used Titebond Original and it worked. Thank you for the help everybody!
