Attach subfence to infeed fence
Place the (2) 1 / 4 - 20 x 3 / 4 " socket head cap screws
with washers through the holes in the subfence and loosely
attach the
1 / 4 - 20 rectangular nuts. (Fasteners supplied in
the auxiliary fence hardware pack) Slide the subfence onto
the infeed fence so the fasteners are captured in the T-slots.
Move the subfence forward until stopped by the outfeed
fence and tighten the fasteners, Fig. 23. Now fine-tune the
fence offset so that the subfence is flush with the outfeed
fence. Always make sure to tighten the black thumbscrew
that ties the two carriages together after making any offset
adjustment.
Position fence for initial profiling cut
Loosen the mounting screws that secure the
subfence about 1 / 2 turn and slide the subfence back away
from the outfeed fence. Move the TWIN’S fence up to the
cutter and position it so the rear face of the subfence is in
line with the approximate center of the cutter. See
overhead view, Fig. 24.
Make the profiling cuts
Turn on the router and using a good rubber soled push
block advance the subfence forward into the cut. When the
subfence touches the outfeed fence, back the subfence out of
the cut and turn off the router. Unlock the carriage clamp and
move the Twin’s fence back about
1 / 8 ". Relock the clamp,
then repeat the cut. Continue this process until you have cut
completely through the subfence.
Slide the subfence into final position
Now you can slide the completed subfence into its
final position on the infeed fence and tighten the mounting
screws. Final positioning should always be done with the
router turned off and the carriage clamp locked.
CAUTION: The nature of zero clearance places the
subfence very close to the cutter. NEVER attempt to
move your fence or make any adjustments to the setup
until the router bit has come to a complete stop.

If you want to add zero clearance to the
outfeed fence as well, make two of the
subfences as described above. Make the profiling
cuts on both pieces from the infeed side. NEVER
make the profiling cut by sliding the subfence into the
cut from the outfeed side.
When cutting what will later become the outfeed
subfence, either drill and counterbore after completing
the profiling cuts, or make sure the counterbore faces
the infeed fence during the cut. The end of the
subfences above the profile will need to be trimmed
off so they can close around the cutter.
