DEEP CUTS
For deeper cuts, make several progressively
deeper cuts by starting with the highest step
on the depth turret, and after each cut, rotate
the depth turret to progressively lower steps
as desired, until the final depth (lowest step
or flat) is reached. Steps progress by 1/8"
increments.
To be certain that your depth settings are as
desired, you may want to make test cuts in
scrap material before beginning work.
FINE ADJUSTMENT
The RA1166 plunge base is equipped with a
fine adjustment system that allows you to
micro adjust the plunge depth of the router bit
for superior routing accuracy.
Each complete revolution of the fine
adjustment stop adjusts the plunging depth
by 1/32", and each of the four indicator marks
on the knob represents 1/128". One of the
four tick marks is larger than the other to
indicate a complete revolution. A reference
indicator line is built in to the depth rod.
To use the fine adjustment knob, once the
depth rod and turret have been set, check
the final depth setting and fine-adjust as
follows:
To micro-increase the plunge depth, raise the
fine adjustment stop by turning it counter-
clockwise by the desired amount.
To micro-reduce the plunge depth, lower the
fine adjustment stop by turning it clockwise
by the desired amount.
Notes:
• When micro-adjusting the plunge depth, it
is more convenient to move the fine
adjustment stop up than down. Before
setting the depth rod and turret, make sure
the fine adjustment stop has been turned
several revolutions clown from its top
position so that it can be adjusted upward.
• The fine adjustment stop cannot be use to
reduce the plunge depth when the depth
rod is already touching the depth stop
turret. The router must be raised before
such an adjustment can be made.
• Also available is an alternative turret that
has an adjustable step which uses an M4
screw for the adjustable step. The
adjustable step makes it possible to make
multiple-pass applications without having
to make a fine depth adjustment even
when the total cutting depth is not a
multiple of 1/8".
