Temporarily clamp the tailpiece to the body, (46) aligned on
center. Place the nut back in the slot, and install the two out-
side strings into the tailpiece and over the bridge saddle.
Space the strings 1-11/16" apart, located equally from the
center of the nut blank. Make pencil marks on each side of
the strings, move the strings aside, and with razor saws
and/or nut slotting files, cut “starter” slots to hold the strings
in place. Keep on the high side of your 3/8" string height for
now
(47) .
Center the cone in the soundwell with equal space all
around. At the saddle, space the strings 2-1/4" apart, located
equally from the center of the saddle, and cut starter notch-
es to hold them. Don’t put too much tension on the strings,
since the tailpiece is not permanently attached yet. Notice
that the 2-1/4" spacing at the saddle is close to the spacing
of the string holes in the tailpiece, making it a relatively
straight string run from tailpiece to saddle.
The string alignment will help you determine if the neck,
cone, saddle, and tailpiece are centered with each other. If
you have been accurate up to this point, the cone should be
centered in the well with a gap of approximately 1/16" all
around the perimeter, and little or no off-center string pull
toward either the bass or treble side. A small amount of
string pull to one side or the other is OK, and the 1/16" gap
between the cone and the soundwell wall allows for such
slight misalignment.
If the alignment of all the parts looks good, drill a 7/64" hole
and fasten the tailpiece to the body with the screw and strap
button supplied. If the tailpiece needs to move a small
amount toward either the bass or treble side to line up with
the saddle and neck centerline, it is OK. (A “small amount”
would be 1/32" to 1/16" maximum). If you need to move the
tailpiece more than that amount, the neck is incorrectly fit to
the body, and may correction. (See “Appendix 1: Neck Fitting
Details” on page 31).
