Gluing cauls can be made to match the radius and length of

the fretboard, and notched to rest over the frets. However, a

simple method that works well for gluing and aligning the

fretboard is to wrap it onto the neck with a large rubber

band. You may need two rubber bands, but one worked

for us.

With the truss rod installed, clamp the peghead into a

swivel- jawed repair vise or to your benchtop, with the neck

overhanging. Cut a broomstick or a scrap of wood as a prop,

and wedge it under the neck heel with just enough force to

push the neck into a slight upbow, or “relief,” of about .012"

or .015", as noted using a straightedge. This will be approxi-

mately the same amount as the slight backbow the fretboard

probably took on during fretting. The two curves, upbow

and backbow, will cancel each other as the fretboard is glued

on, resulting in a straight neck and an unadjusted truss rod.

Lightly spread Titebond glue evenly on the neck surface.

Leave the edges of the truss rod channel almost dry, the glue

squeeze-out will spread right up to the edge of the channel.

Be careful not to get glue in the channel. Set the fretboard on

the glue surface, and align the nut end with the nut line on

the neck. Tie the rubber band at the nut end, and start wrap-

ping (pictured). The fretboard will align itself as you wrap,

and can be easily moved if one edge is off-center. Stretch

the rubber band tightly as you wrap toward the neck heel,

go around the neck joint and the heel, and then wrap back

to the nut. Even with a light glue application, you’ll probably

get a lot of glue squeeze-out. Wipe off excess glue and let

the neck dry overnight.

Installing the fretboard

Let it run through the slot and out the other side. Loose frets

can be clamped using a 16"-radius sanding block as a caul

before running the super glue into the slot. Use wax paper

between the caul and the fretboard.

With ﬂush-ground fret cutters, nip the fret ends close to

the edge of the fretboard (don’t dig into the wood). Use a

smooth mill ﬁle, or sandpaper on the carpenter’s level, to

bring the fret ends ﬂush. Then, holding the fretboard ﬂat

against your work surface, use the mill ﬁle to bevel the fret

ends at about 60°. Work slowly — you can always add more

bevel, but you can’t put the metal back. Lightly round over

the sharp upper edges of the fretboard so they’ll feel com-

fortable to your hand. Our Fret Beveling File makes this job

quick and uniform.
