Gibson
ES-335
Q: I have
79 Gibson 335 and the neck is pulling away from the body on the
underside at the seam (about 1/16th of an inch). It still plays,
but it is affecting the intonation and action. So...just wondering
how the neck is attached to the body and whether it would be a big
effort to try and remove and re-glue the neck? I'm a woodworking
nut and I've built a couple of electric guitars....but this project
has me a bit stumped. Would I need to steam the neck to loosen the
glue joint?
Appreciate any suggestions.
Thanks for your help.

A: As I remember, the 335 has
a mortise and tennon joint. Pull out the 18th fret. Cut the
fingerboard binding on the top treble side corner, by the rhythm
pickup. Peel the binding back to the 16th fret. Be careful to not
chip finish as you peel. Use a razor saw to cut through the rosewood
at the bottom of the 18th fret. The next step is to heat the fingerboard
tongue loose and take it off. The glue holding it together
melts at 120 degrees. I use a Watlow heater blanket.
You have now exposed the mortise and tennon.
Drill holes and inject steam into the joint until it comes loose.
Clean off as much glue as you can while its still wet. Let
the neck and body cavity dry thoroughly, at least over night. Then,
working very carefully, remove wood and add shims until the neck
fits the slot perfectly and has about a 3 degree drop back
from the plane of the top.
These necks were originally put on with hide
glue. By the 70s they used polyvinyl resin white glue. I would use
Titebond or Elmer's Carpenters glue. It's still PVR but it
will hold stain and it melts at a little higher temperature.
Now glue the neck on. One big clamp pinching from the top of the
tennon to the back of the guitar should do the trick. Now refit
and reglue the tongue. Then reglue the binding and reseat
the 18th fret. Now finish up with an action set and new strings,
and you are ready to rock.
