INCRA JIG ULTRA on the
Table Saw
Another way of making box joints is to use INCRA JIG
ULTRA as an incremental fence or stop block on the table saw.
Its usefulness on this machine is also evident in its ability to
cut uniform thin strips off the outside edge of the board. Or, if
you ever need to cut a precisely spaced series of grooves,
INCRA JIG ULTRA at the table saw will handle it with ease.
Have you ever tried to exactly duplicate a cut after moving your
old fence system? With INCRA JIG ULTRA on your table saw,
duplication becomes effortless. No more trial and error cuts.
In fact, you’ll not find a more accurate table saw fence on the
market today.
To use INCRA JIG ULTRA on your table saw, position the
3 /
4
" plywood base on your tabletop as shown in Fig. 18 and
follow the instructions below for zeroing the fence to the blade.
If you wish to cover the notch on your INCRA fence, mount a
wooden auxiliary fence as described on page 7 of your INCRA
PRO Fence System Owner’s Manual. Or, if you prefer, a
notchless version of the INCRA PRO Fence is available. (See
order information at the back of this manual.)
“Zeroing” the fence to the blade
With the motor unplugged, raise your table saw blade to
about 2". Loosen the C-clamps that secure the wooden base
to your table saw. “Unlock” the carriage clamp and slide the
fence up to the blade then “lock” the carriage clamp back in
place. Carefully position the entire assembly so that the fence
is centered on the tabletop and “kissing” the blade. See Fig. 19.
Be gentle when positioning the fence adjacent to the blade so
that you don’t deflect the blade. Clamp the plywood base to
the tabletop with the (2) C-clamps, being careful not to shift the
base. Now slide the middle “primary” scale to position the 0"
mark directly under the cursor. You have now positioned the
fence parallel to the blade and set the fence to blade distance
at zero.
On some table saws you may find the 0" mark will not
reach the hairline cursor. To remedy this, simply move the
hairline cursor to the rear of the base. See Fig. 12 on page 8.
Once you have “zeroed” the INCRA JIG
ULTRA on your table saw, glue and screw a
1" x 2" piece of hardwood to the underside of
the plywood base adjacent to the right edge of the
table saw. See Fig. 20. The 1" x 2" should be
about as long as the plywood base. Make sure it is
butted up against the right edge of the table saw
before screwing in place. Now, should you need to
remove the INCRA JIG ULTRA from the table saw,
you can quickly reinstall it in the exact position as
before by butting the 1" x 2" against the right edge
of the saw and clamping the plywood base in place.
