Be sure that the gluing surfaces of the neck joint and

fretboard extension are free from dirt, ﬁnish and bufﬁng

residue.

If your neck has a dovetail, press it, with the shim on the cor-

rect side, into the body. The joint will be a bit tight due to the

thickness of the lacquer. If the neck and its shim go all the

way down into the neck block, you can ignore the lacquer

on the sides around the dovetail opening and glue the neck

right over the ﬁnish. If they’re too tight, ﬁle a tiny amount of

wood off the shim until the neck seats correctly.

You’ll need a 5° tapered and padded wedge to protect the

back of the body and to provide a clamping surface, and the

shoulder brace caul you made earlier (in “Bridge and shoul-

der brace clamping cauls” section). Place it inside the guitar

between the tall shoulder brace and the ﬂat shoulder brace

as a surface for clamping through the soundhole. You’ll also

need a clamping caul for the fretboard extension; we made

one from a 16"-radius wooden sanding block, and notched

to ﬁt over the frets. Clamp the neck into the body (pictured),

and use a sharp razor knife to cut through the ﬁnish around

the fretboard extension. Don’t cut into the soundboard!

Remove the neck. The lacquer ﬁnish on the soundboard in-

side the scribed line must be removed with a chemical paint

stripper. You MUST be careful when applying and removing

the stripper — don’t get it outside the scribed line!

Mask the soundboard to protect the lacquer ﬁnish from

accidental splashing. Use low-tack drafting tape to fasten

Final assembly and setup

Prepare for neck installation

For the bolt-on neck, glue is needed only under the fretboard

extension. LIGHTLY clamp the neck and the fretboard ex-

tension down onto the body, and then tighten both neck

mounting bolts ﬁrmly through the soundhole. Now apply full

clamping pressure, using clamps and shoulder brace cauls as

you did when “dry-clamping” before stripping the lacquer.

Wipe off the excess glue for about ﬁve to ten minutes as it

squeezes out, using a clean damp cloth.

Remove the clamps after the glue has dried.

For the dovetail neck, apply Titebond glue to the underside

of the fretboard extension, the two sides of the dovetail,

and if you wish, add a small amount on the interior walls of

the neck block dovetail mortise. Be sure glue contacts both

sides of the shim, too.

Slide the dovetail neck and the shim in place and apply

your clamps and cauls as you did when “dry-clamping”

before stripping the lacquer. Wipe off the excess glue for

about ﬁve to ten minutes as it squeezes out, using a clean

damp cloth.

Install the neck

clean paper on the soundboard around the area. Keep the

tape away from the line by 1/16" so the stripper won’t touch

or overlap the tape. Stripper will soften the solvent in the

tape’s adhesive, which will cause a permanent wrinkle in

the new ﬁnish.

Apply stripper with a small artist’s brush. Allow sufﬁcient

time for the stripper to loosen the ﬁnish, and then slowly

remove small bits of the ﬁnish with a 1/2" chisel used as a

vertical scraper. Always pull the stripper inward from the

edge of the line to the center of the area to be stripped. After

each pull, wipe the residue from the chisel with a scrap of

paper towel, which should be carefully lifted away from the

area for disposal. When all the old ﬁnish is removed, wipe

the exposed wood carefully with a damp cloth to neutralize

the remaining stripper, and let the surface dry.
