Installing a truss rod
Q: Hi i found yur e-mail address on
the net and i was wondering if you could help me with a bit of guitar
advice regarding glueing in a martin style U chennel truss rod.
When gluing in the rod do you glue the sides of the rod to the sides
of the channel, or the bottom of the rod to the bottom of the channel,
or glue both the bottom and sides of the rod into the channel? Also
what is the significace of inserting a small cover of wood or other
material over the truss rod once it is installed?
Any help you could give would be greatly appreciated.

A: The truss rod should press fit into
the slot. The only thing
that glue will do is to assure that there will be no buzzing between
the rod and the slot. Be careful not to get glue into the inside
of the u-rod, it could gum up its function. The wood rod cover is to facilitate fitting the fingerboard. The bottom of the fingerboard
and the top of the neck must be flattened to make a perfect joint. It is a lot easier to
sand wood than metal. Press
in the rod. Glue in
the wood rod cover. Plenty
of glue will trickle down to seal the rod in.
