Kay upright bass
Q: I have a Kay upright bass. From time to time
the plywood edges start separating and they need to be re-glued.
Is a Titebond Liquid Hide Glue a good choice or would Elmer’s
wood glue be better?
A: I have always used medium viscosity superglue.
It is clear and looks like finish when it dries. If there is bare
wood, as well as separations, you can stain it with a felt pen before
you put the glue on. For a dark brown Bass I start with a light
tan pen. The wood soaks up the ink and gets much darker. If you
started with a dark brown pen it would be way too dark.
I have a special prejudice against Titebond Hide
glue. Hide glue is the finest glue available for most projects.
Titebond Hide has very little in common with real Hide glue. And,
the Titebond needs to be fresh to work at all and because of its
very limited appeal, I have never seen a bottle that wasn't past
its expiration date. Elmer's wood glue would work, and it would
be easier to clean up any slops. The joints will swell, but
then shrink down again as the glue dries. The ink trick still works
but you are covering it with a semi-opaque soft plastic. If
there are gaps and unevennesses to fill, superglue will fill them.
Elmer's will just shrink down into them. Most of the volume of Elmer's
is water which goes away as it dries. It would take many applications
to do any filling.
Please note that I said medium viscosity, like
a Stew-Mac #20. Hardware stores stock only the watery kind, which
would all disappear into the wood, and the thick kind which might
work but tends to glob. Have a rag and superglue solvent ready in
case of drips. A steady hand is much more effective than clean up.
Test the flow rate on a tongue depressor before you risk your bass.
Kicker can make the super glue dry almost instantly, but air drying,
while slower will give you a smoother surface. If you have a big
gap to fill, carve and fit a piece of tongue depressor into the
hole. For a very small hole, spray it lightly with kicker first.
This will make the glue dry from the bottom up. If you fill the
hole with a puddle of glue and then shoot kicker, the surface will
harden, sealing liquid glue underneath. If your final surface is
bumpy or spikey, smooth it down with knives, files, sand papers
and a little steel wool. Avoid letting your smoothing tools touch
the original finish.
