Mounting the INCRA PRO Fence …
…to the INCRA JIG ULTRA or
ULTRA LITE:
Insert the #10
screws through the thick (gold) washers then through
the holes on the back of the fence mounting bracket.
Place a thin (silver) washer on each screw then loosely
attach the rectangular nut. See Fig. 4. The raised
rim on the rectangular nut should face the mounting
bracket. Now slide the fence onto the thin washer and
rectangular nut so that both are captured in the T-slot
on the back of the fence. Make sure the washer is
captured in the T-slot provided as shown in Detail 4a.
Position the fence so that the carriage is approximately
centered on the fence length and tighten the two
mounting screws.
To achieve a silky smooth carriage motion, it
is important that your table surface be flat and
-smooth, and that the carriage be installed parallel
to it. If you find that your carriage tends to bind slightly
during some portions of its travel, the following
additional step should take care of it. Simply place 3
or 4 pieces of paper under the infeed end of the fence
before tightening the screws in the final step of the
fence mounting procedure described above, and then
remove the paper. If the problem still persists, either
add a few more pieces of paper, or place the paper
under the other end of the fence before tightening.

choice and with the INCRA Jig set to midrange, check the angle of your fence to the
table using a machinist’s or carpenter’s square.
Sometimes, as a result of the plywood base
not being perfectly flat, the angle may be
slightly more or less than 90°. To correct the
angle, place a masking tape shim along the
length of the mounting bracket between the
bracket and the fence as shown in Fig. 8.

32 x 1⁄2" thumbscrew, 5⁄ 8" o.d. nylon
washer and rectangular nut as shown.
A second Stop Extender Bar can be purchased
should you want to increase the stop range beyond both
ends of your INCRA PRO Fence.
CAUTION: Always install the Extender Bar in the UPPER
T-slot, never the lower one.
Extender Bar Stop
Position the Extender Bar about 2" beyond the fence end
and using the supplied 1⁄4"
attach the Extender Bar Stop. See Fig. 10. The Stop can
be used on either end of the Extender Bar to increase
your stop range beyond the ends of the INCRA PRO
Fence. When not in use, the Stop can be turned around
and locked to the Extender Bar (see Fig. 11). This storage
position places the Stop out of the way, leaving the front
face of the INCRA PRO Fence uninterrupted for through
cut operations.

Applications
INCRA Stop
When used in conjunction with your new INCRA PRO
Fence, the INCRA Stop provides the same precise rack
positioning capabilities that your INCRA Jig offers. The
sliding scale in the top of your fence becomes a versatile
reference for use in setting stop positions at the router
table and the drill press. The sliding plastic stop strip
on the INCRA Stop permits micro-adjusting of the stop
positions between 1⁄32" steps. The Stop can function
on either the outfeed or infeed end of the fence with any
thickness of stock, even rabbeted boards. Two INCRA
Stops can work together at opposite ends of the fence for
many advanced operations, such as multiple mortises and
slots.

Zeroing the INCRA Stop to
the End of a Board
For most applications, you will be using your
INCRA Stop on the outfeed end of the INCRA
Fence to control the length of a cut relative to
the front end of the board. Here is how to set
the initial scale position for this type of setup:
After installing the bit you wish to use,
set the fence to bit distance at about 1".
1
Place a square cut piece of scrap stock
against the fence with the end of the board
against the infeed side of the bit. Turn the bit to
find the high spot.
FIG. 13
Top view of
stop setup
INCRA
Stop
First:
Slide the board
up to contact
the “high spot”
on the bit
Next, lock the INCRA Stop to the fence on
the outfeed side of the bit with the plastic
2
stop strip as close as possible to the end
of the board. Adjust the position of the stop
strip until both the strip and the bit contact the
end of the board. See Fig. 13.
You now have the choice of setting
the sliding scale to one of three initial
3
positions:
In most cases, you will simply slide the
A
scale to align the 0" mark on the scale
with the end of the INCRA Stop nearest the
bit. When set to this initial position, the scale
reading at any subsequent INCRA Stop location
will give you a direct readout of the total length
of the cut. (See Dimension “A”, Fig. 14.)
If you wish the subsequent scale readings
B
to reflect the distance from the front end of
the board to the center of the cut (Dimension
“B”, Fig. 14), slide the scale to an initial reading
under the end of the INCRA Stop equal to
minus one half of the bit diameter. Example:
If you are using a 1⁄2" diameter bit, complete
Steps 1 and 2 above then slide the scale to
read negative 1⁄4".
If you want the scale reading for future
C
INCRA Stop locations to reflect the
distance between the end of the board and the
outfeed edge of the cutter (Dimension “C”, Fig.
14), then slide the scale to an initial reading
equal to minus the bit diameter.

X-Y Positioner for the Drill Press
Used at your drill press, your new INCRA Jig and INCRA
PRO Fence System are the ultimate in X-Y positioning
control. You can quickly and accurately locate and drill
any pattern of holes by simply moving the INCRA Jig
and the INCRA Stop to the desired settings. A cribbage
board is a good example of a project that requires this
ability. And since you can locate any hole to within a few
thousandths of an inch, you will find this technique great
for making perfect dowel joints.
Mounting an Auxiliary Fence to
Your INCRA PRO Fence
If you should desire to use a router bit with a diameter
greater than 3⁄4", you must first mount a wooden auxiliary
fence to your INCRA PRO Fence. The following
information should help in determining the dimensions of
the auxiliary fence, see Fig. 17.
Thickness (A): The thickness of the auxiliary fence should
be 11⁄2 times the diameter of the router bit you plan to use.
(Example: To use a 1" diameter router bit, your auxiliary
fence should be 11⁄2" thick.)
Height (B): The height of the auxiliary fence should be 3"
minimum.
Length (C): Cut the length of the auxiliary fence to match
the length of your INCRA PRO Fence, either 18" or 28".
Fence Notch Width (D): At least 1⁄4" greater than the
diameter of the router bit.
Fence Notch Height (E): At least 1⁄4" greater than the
maximum depth of cut you plan to use with the router bit.
To mount the auxiliary fence to your INCRA PRO
Fence, you will need (2) #8
flat washers and (2) #8
machine screws should be slightly less than the thickness
of the auxiliary fence. Drill two 3⁄16" dia. through holes
in the auxiliary fence in the locations shown in Fig. 18.
Now, using a 1⁄2" diameter drill bit, counterbore the hole
locations.
Note: Adjust the depth of the counterbore so that the
screw, when installed in the counter bore with the #8 flat
washer, extends slightly less than 3⁄4" through the back of
the auxiliary fence. Loosely attach the #8
the screws then slide the hex nuts into the T-slot located
on the front face of the INCRA PRO Fence. Tighten the
machine screws to secure the auxiliary fence in place.

For short term auxiliary fence applications, you
might find it convenient to use an aggressive
double-faced tape to attach the auxiliary fence. We
recommend #ST501 manufactured by SpecTape of Texas.
Call 1-800-442-1338 for your nearest distributor, or check
with your INCRA dealer. Do not use standard double-faced
carpet tape.
