If you wish to add a
3
⁄
4
" thick table board between the right
hand extension wing of your table saw and the TS III base
mount assembly, begin by making two of the wooden
supports like the one shown in
. For the length of
the support, measure the distance between your extension
wing and the base mount assembly. Loosely attach the
fasteners through the holes in the supports. Remove the
base assembly from your saw, then slide the square nuts
into the inside T-slots on each rail,
. Cut a table
board to fit and screw to the supports. The oversize holes
in the support should allow range for positioning the table
board flush with your table saw top.
If, after reinstalling the blade guard and tilting the motor, you
find that the rear rail interferes with the blade guard, you
must add the two remaining rail mounting brackets and split
the rear rail to provide the necessary clearance as shown in
. Begin by removing the base mount assembly.
Loosen the bolts that secure the rear rail to the existing
brackets and slide the rail off. Reinstall the blade guard,
then locate the positions for the additional rail mounting
brackets on either side of the blade guard. The mounting
brackets should be placed as close as possible to the blade
guard, but before drilling the mounting holes, make sure to
check the positions for clearance when the blade is tilted to
45°. When you have found the mounting bracket locations,
drill a
3
⁄
8
"diameter hole in the center of each position. The
center of the hole should be about 1
1

" below the table top.
Remove blade guard, then using
3

–16 x 1
1
⁄

" hex bolts,
nuts and washers, attach the extra mounting brackets
loosely in place. Install the rail bolts as shown in
on
page 4, then slide the rear rail back into position. Tighten
all rail mounting bolts, then tighten the two bolts that secure
the brackets to your table saw. Use a hacksaw to make a
cut through the rear rail about halfway between the two
additional rail mounting brackets. Loosen the bolts that
secure the rails to the brackets and slide the rails to create
an opening large enough to reinstall the blade guard. See
. Again, tilt the blade to 45° to check for clearance.
Once the rail positions are established, sand or file the cut
ends of the rails to remove any sharp edges. Tighten the
bolts that secure the rails, then repeat the alignment and
calibrations starting with
on page 7.
