Attach the Incra Jig Ultra
Lite to a
3/4
” plywood base
Begin with a piece of
3
⁄
4
" plywood (or
hardwood) that is 8" wide. The length of the
plywood should match the width of your
router table. Clamp the plywood to the edge
of your router table using (2) C-clamps.
Mark the center of the plywoodʼs length and
position the operatorʼs side of the Ultra Liteʼs
base 2
1
⁄
4
" from the center mark. See Fig. 1.
Attach the base to the plywood through the
six holes using (6) #10 x
7
⁄
8
" phillips pan
head wood screws and #10 flat washers.
Attach hairline cursor
to base
Place one of the #6 flat washers on each of
the #6-32 x
3
⁄
8
" screws. Insert the screws
through the holes in the plastic cursor and
loosely attach the #6-32 hex nuts. slide the
two nuts into the T-slot at the front of the
Ultra Liteʼs base as shown in Fig. 1a. Align
the cursor flush with edge of the base and
tighten the mounting screws.
Attach the Incra Fence
With the plywood base still clamped to
the edge of your router table, carefully slide
the carriage into the base and pull the
carriage clamp up into the locked position.
Insert the #10-32 x 1
1
⁄
8
" phillips pan head
screws through the thick (gold) washers,
then through the holes on the back of the
fence mounting bracket. Place a thin (silver)
washer on the end of each screw, then
loosely attach the rectangular nut. See
Fig. 2. The raised rim on the nut should
face toward the mounting bracket. Now
slide the thin washer and rectangular nut
into the T-slot on the back of the Incra
Fence. Make sure the thin washer is
captured in the T-slot provided as shown in
Fig 3. Position the fence so that the
mounting bracket is approximately centered
on the fence length and tighten the two
mounting screws.

Attach the Incra Fence
To achieve a silky smooth
carriage motion when moving the
fence, it is important that your table
surface is flat and smooth. If you find
that your carriage tends to bind slightly
during some portion of its travel, try
loosening the fence mounting screws
then retightening at different locations
along the tableʼs length.

Adjusting the fence angle
After mounting the Incra Fence to your
Ultra Lite, check the angle of the fence to
the router table using a machinistʼs or
carpenterʼs square. Sometimes, as a result
of the plywood not being perfectly flat, the
angle may be slightly more or less than 90°.
To correct the angle, place a masking tape
shim between the mounting bracket and the
fence as shown in Fig. 5.
Assemble stop positioner
Place a #8 flat washer on each of the
(2) #8-32 x

" thumb screws and insert
through two of the holes in the black plastic
stop positioner. Loosely install the (2) #8-32
hex nuts, then slide the nuts into the T-slot
on the front of the Incra Fence. Fig. 4.
When not in use, simply slide the stop
positioner off the fence.
If you wish to upgrade your Incra
Fence to add the ultra-precise stop
positioning abilities of the New Incra
Stop, see the fence upgrade
package offered on page 16.

MAINTENANCE
In general, just keeping your Incra Jig clean is all
you need to do to keep the tool in tip top shape.
Occasionally, remove the carriage from the base and
brush or blow out any sawdust or debris that may have
accumulated on the base and the UHMW guide
bearing strips. Use a toothbrush to clean the teeth
on the Incra racks on both the carriage clamp and
on the carriage.
