7. Mount the Preamp
Slip the wooden spacer block (prepared earlier) over the control bushings and
mount the preamp. The outside hardware should include a smooth 3/8" dress wash-
er and a 3/8" hex nut. Tighten the hex nut.
8. Prepare the Endblock
There are two ways to widen the endpin hole to accept the endpin jack:
Slow and Safe
If you have the time, this is the preferred way to enlarge the endpin hole. Remove
the endpin and widen the hole to size with a 15/32'" (11.9mm) reamer, available in
the US & Canada through Stewart MacDonald, 800-848-2273, part #4323.
Quick & Clean
The objective here is to drill out the hole with the endpin or other suitable plug in
place. You may remove a loose endpin and refasten it in the endblock with cyano-
acrylate glue before starting the procedure.
Note: We do not recommend this method for instruments with brittle orna-
mental veneers (ex: abalone) around the endblock.
1. Apply masking tape around the endblock area to protect the instrument.
2. Locate an X-Acto saw blade 1/16" (1.6mm) away from the body and saw off the
endpin.
3. Centerpunch a guide hole in the center of the trimmed endpin.
4. Drill a 1/8" (3.2mm) pilot hole through the endblock.
5. Line up a 15/32" (11.9mm) Spade bit in the pilot hole and begin drilling. Maintain
a perpendicular plunge in relation to the instrument. Use steady (but not heavy)
pressure, especially as the drill exits inside the guitar.
6. To avoid damage to the instrument, let the drill come to a complete stop before
removing it from the hole.
