You’ll notice one or more thin plastic shims in the
cavity behind the metal spring engager, Fig. 34.
To change the clamping pressure, simply add or
remove shims. If you want to increase clamping
pressure, add one of the supplied shims. If you want
to decrease clamping pressure, remove one of the
thin shims. The matte nish shim is .005, the clear
shim is .010” and the white shim is .020”. When
making adjustments, add or remove only .005”
at a time, and keep the thinner shims between
the metal spring engager and the white shim,
Fig. 35. Press the metal spring engager forward
with your nger and slide the black UHMW bearing
pad between the shims and the carriage clamp.
Note: You will notice a piece of thick tape adhered
to one face of the black UHMW clamping pad.
When reinstalling the clamping pad, make sure
the taped surface is facing away from the carriage
clamp, Fig. 34.
Press the UHMW bearing pad forward and reinstall
the set screw.
Realigning the Fence Racks
To check or adjust the alignment between the INCRA
positioning racks attached to the back of your Pro II
Fence, begin by loosening the fasteners securing the
racks to the fence. Align the first rack flush with the
end of your fence and tighten the fasteners. Now,
clamp the INCRA Shop Stop to your fence so that it
bridges the gap between the ends of racks #1 and
#2 as shown in Fig. 36 and tighten the mounting
screws for rack #2. Next, move the Shop Stop to
bridge the gap between racks #2 and #3 and tighten
the mounting screws for rack #3. Finally, bridge the
gap between racks #3 and #4 and tighten the rack #4
mounting screws. This process aligns the racks so
that the Shop Stop will operate accurately along the
entire length of the fence. The racks on the Wonder
Fence can be aligned in the same way.
CAUTION: Whenever making clamping
pressure adjustments, always make sure
that adequate pressure remains to hold the
carriage rigidly in place when clamped in
the fully extended position.

AUTO CENTERING SCALE
(
ImperIal model only
)
Before installing any of the INCRA joinery templates in
preparation for cutting a dovetail or box joint you must
first position your fence so that the router bit is aligned
with the center of your board’s width. This can be
done using the manual “centering” method described
on pages 3-4 of the INCRA Master Reference Guide
& Template Library. The manual method does require
a trial cut on a scrap of wood but it will work on any
width of stock. However, if you are working with a
board width that is some multiple of
1
16 you’ll find
the INCRA Auto Centering Scale provides a quick and
easy way to find the center that requires no trial cuts!
