Fingerboardglueing: AR-Glue or epoxy?

[Herman]

A few times I had a backbow in a rough neck, because the glue (Titebond and LMI white glue) did swell the fingerboardside of the neck. I corrected it with sanding it flat, correct it with a two-way rod or even taking the fingerboard off.
I discussed it with my local luthier, and he told me he puts the fingerboards on with epoxy with better (flatter) results.

On my latest I recently took the fingerboard off and reglued with epoxy: Flat now.

Opinions?

I believe the main problem is that --way too much glue is used for the job. I see pixs of clamping set-ups with the Titebond dripping all over the place. Too much glue = too much water. A thin film is all that is needed. A full length caul and many clamps are essential. http://www.kennethmichaelguitars.com/ne ... embly.html
That said I see no reason for not using epoxy.

I'd say the best reason for not using epoxy is future removal if necessary.

I've found that gorilla glue works good for fingerboards. I only dampen the fingerboard a little to help the process. I use hide glue for the part you glue to the top. I have used heat to remove both from the body and neck.

I just had an experience with LMI instrument glue on an ebony fret board where I used a thin layer of glue on the same day I planed off 2 mm from the back of the fret board and it really warped across its width. Enough so that I saw a slight gap while trying to clamp the fret board. I had a full sized 3/4 inch caul. I removed the board, cleaned the glue and flattened it with heat, the caul and some clamps and re-glued with epoxy.

It is a classical with a Spanish heel so the only reason I would removed the fret board would be to replace it. Epoxy will release with heat.

Epoxy for me every time.

Epoxy removes just as easily as other types of glue, anything above 100 degrees C and the epoxy looses all bonding properties.
