INCRA Twin Linear - Manual (Page 9)

Micro Adjusting
The micro adjust feature of your
INCRA TWIN allows for precise
positioning of the fence to any
location between the
1 / 32 " tooth
spacing of the INCRA sawtoothed
racks. You’ll find this feature
extremely handy the next time you
need to widen a mortise by a hair
for a great fitting mortise and tenon
joint. Use the micro adjuster for a
flawless fit when cutting grooves to
accept inlay strips or to loosen up a
tight-fitting box joint cut with an
undersized bit. You’ll find it
especially useful for setup
operations like “zeroing” or
“centering”. Here’s a step-by-step
look at operating your INCRA
TWIN’s micro adjuster. See Fig. 15
as you follow the steps.
Pivot flip clip into
position under
carriage clamp
Micro adjustments are always made
with the carriage clamp halfway
between clamped and unclamped.
The spring-loaded flip clip will hold
the carriage clamp in this half-
clamped micro adjust mode position.
Use your right hand to quickly pivot it
in or out as necessary.
Unlock the carriage clamp
With the flip clip in place, the carriage clamp will
automatically spring to the micro adjust mode.
Micro adjust the fence position
Rotate the knob with the red dial located at the rear
end of the outfeed (gold) carriage. Turn the micro adjust
knob clockwise to move the fence toward the cutter, or
counterclockwise to move the fence away from the cutter.
Lock the carriage clamp
Pull the carriage clamp up to lock the carriage in
place, then pivot the flip clip back to its original position.
Gauging the distance moved when micro adjusting is easy.
A full turn of the knob equals
1 / 32 " of movement, a half turn
equals 1 / 64 ". For smaller adjustments, the red dial is marked
in 1 / 1000 " increments. After micro adjusting you can re-zero
the dial to the pointer by rotating the dial (not the knob) with
your fingers. See Fig. 16.
The micro adjust feature of the INCRA TWIN has an
adjustment range of +
1 / 4 " from mid-range. The range scale
decal on the carriage shows how much range remains in
either direction. To read the scale, just sight along the end of
the gold bar that overlaps the decal. Fig. 16.

NOTE
Do not continue to turn the micro adjust knob counterclockwise beyond the
minus 1 ⁄ 4 " range shown on the decal. If the knob is unscrewed beyond this
point, factory reinstallation may be required.
To avoid running out of micro adjustment
range in the middle of a project, you want to
remember two things: First, always micro adjust
back to mid-range before beginning a new project.
Second, whenever you need to micro adjust a
distance greater than
1 ⁄ 32 ", use the INCRA positioning
racks to get as close as possible before reaching for
the micro adjust knob.
