This is why I cannot recommend Titebond III for gluing two sheets to produce a thick stabilizer. It was straight as could be when it was removed from the press. I think the problen is Titebond III is water soluable. I have used Titebond I with good results.

Bill, I had that same problem with Titebond ll. (had great results with the original Titebond, then this!
I would rather use glue for laminating sheets, but have since relented to the epoxy-spread-with-credit card method. Sticky and messy, but that's the 'journey'. Destination was a straight rudder and stab, and the bonus was their light weight!

All Titebond is water soluble, can be thinned with water to paint it on foam or whatever and is really my choice for hardwoods, but when you spread it on sheet balsa it will warp it.
Epoxy is my coice for lamination and I like to add a piece of cabon veil between the sheets for added stiffness.
Blessings,

There is one way to use alipahatics for laminating. Paint a ver thin coat on each side fo the surfaces to be joined, then let it dry COMPLETELY.
Put the two pieces togeter (glued sides touching) and IRON them woth a lot of heat. The heat polymerizes the glue and makes it stick. I sheeted a foam wing this way and it worked fine.
Really you are better off using epoxy...

If I have some way to clamp what I am laminating I use Gorilla glue works for me. But If I can't clamp the whole thing it does expand and will warp a little. Of course all my planes are warped a little LL~ LL~ LL~ HB~>
I only use Titebond no numbers. The others really don't have enough advantage to make it worth it. I'm a cabinet maker and carpenter so I've had a little experience. Oh don't use Gorilla glue if you can't clamp it or you'll have a big mess. And there's no known way to remove it.

I'll second what Mike says about Gorilla glue. It also makes for very stiff peices as it penitrates the wood while curing. DOC Holliday

I love Gorilla glue for all the inner joints on my guitars & basses but it's a bear to clean up. But - the place I love it the most is for foam! We all are familiar with the slip of the knife or whatever pulling the little beads out and leaving a void but the old GG fills those in and with the expansion remains very light. The excess just foams out of the joint to be trimmed off after hardening. It's great stuff when used in the right places!
