OPERATION
Moving to a New Scale Setting
To use your INCRA JIG ULTRA, clamp the plywood base to
the stationary tool of your choice. (See the APPLICATIONS
section beginning on page 8 for specific setup recommenda-
tions for the router table, table saw, and drill press.) Moving
the fence to any new position is simple. First, push the
carriage clamp down to “unlock”, then grasp the fence
mounting bracket as shown in Fig. 5 and slide the fence to
the new position. Remember, whenever moving the INCRA
JIG ULTRA’s carriage and fence to any new position, always
align the mark on the scale or template directly under the
hairline cursor before locking the carriage clamp in place.
To secure the carriage at the new scale location, simply pull
the carriage clamp handle up into the “locked” position.
When moving the carriage, take care not to accidentally
slide the scale in its slot.
CAUTION: For your safety, keep both hands behind the fence
when moving to any new scale position.
Micro Adjusting
The micro adjust feature of your new INCRA JIG ULTRA
allows for precise positioning of the fence to any location
between the
1 /
32
" tooth spacing of the INCRA racks. You’ll find
this feature extremely handy the next time you want to widen a
mortise by a few thousandths of an inch at the router table or
for shaving a “hair” off the width of a tenon cut at the table saw
for a great fitting mortise and tenon joint. Use the micro
adjuster when cutting grooves to accept inlay strips for a
flawless fit, or to loosen up a tight fitting box joint cut with an
undersized bit. You’ll find it extremely useful when “zeroing”
the fence to the bit or blade or for “centering” the cutter on your
workpiece when setting up for joinery operations. Let’s use a
“hands on” step-by-step approach to getting acquainted with
and using the various components of this important feature.
NOTE: Before you micro adjust your fence position, you will
usually want to make sure that the micro adjust scale reads “0”
under the cursor. To adjust, simply rotate the scale (not the
knob) with your fingers. See Fig. 6. Now let’s micro adjust the
fence forward
