Step 2. Clamp INCRA Jig body halves
together.
IMPORTANT: Before proceeding, make sure that the
racks installed in Step 1 are still a little loose .
Place the two INCRA Jig body halves together as shown
in Fig. 2 and install the carriage bolt, large washer and
2-wing clamping knob from hardware pack D-01.
IMPORTANT: The body half
with the scale should be on
the bottom. Set the top half to
a position of about 5 inches
(not critical) as indicated on the
bottom scale, then tighten the
clamping knob. Now securely
tighten all (8) Phillips screws,
Fig 2A. This procedure aligns
the racks automatically and
perfectly.
Step 1. Attach sawtooth positioning racks.
Begin by assembling the (4) INCRA sawtooth racks to
the (2) INCRA Jig body halves. Place a rack into one of
the receiving grooves and align the mounting holes.
Now place the 8-32 hex nuts from hardware pack D-01
into the hex recesses on the rack and loosely fasten
using the 8-32 Phillips screws with washers, Fig. 1.
Repeat for all of the remaining racks. For now, finger
tighten only. The racks should still be loose enough to
shift slightly back and forth.

Step 3. Attach INCRA Jig to base
panel.
To attach the INCRA Jig to your router table,
you’ll need a piece of 3/4” thick by 9” wide
plywood or MDF that’s long enough to span
the width of your router table. Remove the top
half of your INCRA Jig and center the bottom
half, scale side up on the panel. (Be sure the
carriage bolt is properly installed from
underneath as shown.) Center and square the
INCRA Jig on the panel, then attach it with the
#10 x 1” wood screws with washers included
in hardware pack D-02. Now replace the top
half of the INCRA Jig along with the washer
and clamping knob. Secure the base to your
router table with a pair of C-clamps as shown
in Fig. 3, or if your router table is “INCRA-
ready”, with slotted holes, you can attach the
base panel with user provided T-bolts,
washers and clamping knobs, Fig. 3A. Just
drill holes in the base panel to align with your
router table slots.
Use C-clamps to attach a 3/4” thick by
9” wide plywood or MDF base panel to
your router table . . .

… or, if your router table is “INCRA-ready” with
built-in mounting slots, you can attach the base
panel with T- bolts, washers and knobs for
greater ease of use
