Option 1: threads down (into feet)
Start each hole with a single fl ute countersink. Drill
the holes for the posts with a #9 (5mm) tap drill. Drill
to a depth of no less than 1 ¾" (44.45mm).

If you have an "extension tap," use it now to tap the
threads to a depth of 1" (25.4mm) into the feet. If
you don't have an extension tap, wait until you cut
off the feet to tap out the threads. In these cases,
start the tap from the top of the foot.
Before you cut off the feet, line up the "B" lines on
the legs so they are parallel to the saw blade. Place
the side of the bridge that faces the tailpiece down
towards the table. Line F must be perpendicular to
the blade or the wheels will not align properly. If
necessary, shim up the bridge to make line B parallel
and line F perpendicular to the saw blade. Double
sided carpet tape makes an excellent temporary
clamp while you cut.
After you cut off the feet, enlarge the holes in the
legs to ¼" (6.4mm) diameter.
Option 2: threads up (into legs)
Start a hole in one foot with a single fl ute counter-
sink. Then use a #9 (5mm) tap drill to plunge the
hole in one leg to a depth of at least 2" (50.8mm).
With the bridge still held in position from the fi rst
hole, enlarge it to ¼" (6.4mm) diameter, to a depth
of 1" (25.4mm). Repeat this entire procedure for the
other leg.
Tap the appropriate threads into the legs. If you have
an "extension tap," you will be able to thread all the
way into the bottom of the hole. If you don't have an
"extension tap," the threads won't reach completely
into the legs. This is not a problem; you can go back
and fi nish tapping the threads after you cut off the
feet. But try to at least get the tap started into the
upper part of the legs. This will ensure good thread
alignment when you fi nish tapping after the feet are
cut off.
Before you cut off the feet, line up the "B" lines on
the legs so they are parallel to the saw blade. Place
the side of the bridge that faces the tailpiece down
towards the table. Line F must be perpendicular to
the blade or the wheels will not align properly. If
necessary, shim up the bridge. Double sided carpet
tape makes an excellent temporary clamp while you cut.
Fit the wheels
Once you have cut off the feet, fi t the wheels with
the bridge off of the bass. The hot side of the pickup
should lay absolutely fl at against the bridge, with no
gaps or voids. If necessary, sand the wood fl at at the
contact point and/or increase the depth/diameter of
hole before installing the bridge on the bass (fi gure 1).
Setup
Once the wheels are mounted and the bass is tuned
up, thread the white wire through one of the wing
holes in the bridge and hold it in place with one of
the neoprene plugs from the kit (fi gure 2).
Fasten the output jack behind the bridge and
between two adjacent pairs of strings. Then fasten
the RCA plug into the back of the output jack.
