INCRA LS Positioner Owner’s Manual 15
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 finish 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 finger 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.

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!
