OPERATION
DEPTH OF CUT
As previously mentioned, the depth of cut is impor-
tant because if affects the rate of feed which, in turn,
affects the quality of a cut (and, also, the possibility
of damage to your router motor and bit) A deep cut
requires a slower feed than a shallow one; and atoo
deep cut will cause you to slow the feed so much
that the bit Is no longer cutting, it is scraping, in-
stead
Making a deep cut is never advisable. The smaller
bits -- especially those only 1/16 inch tn dlameteT
-- are easily broken off when subjected to too much
side thrust. A large enough bit may not be broken off,
but if the cut is too deep a tough cut will result --
and it may be very difficult to guide arrd control the
bit as desired. For these reasons, we recommend
that you do not exceed 1/8 inch depth of cut in a
single pass, regardless of the bit size or the softness
or condition of the workplece See Figure
To make deeper cuts It is therefore necessary to
make as marry successive passes as required, lower-
ing the bit 1/8 inch for each new pass. In order to
save time, do all the cutting necessary at one depth
setting, before lowering the bit for the next pass.
This will also assure a uniform depth when the final
pass is completed See Figure 8
DIRECTION OF FEED AND THRUST
The router motor and bit revolve in a o_ockw_se direc
tlon. This gives the tool a slight tendency to twist (in
your hands) in a counterclockwise direction,
especially when the motor revs up (as at startbrg)
Because of the extremely high speed of bit rotation
during a "proper feeding" operation, there is very lit-
tle kickback to contend with under normal condi-
tions However, should the bit strike a knot, hard
grain, foreigr_ object, etc that would affect the nor
ms] progress of the cutting action, there will be a
slight kickback -- sufficient to spoil the trueness of
your cut if you are not prepared. Such a kickback is
always In the direction opposite to the direction of
bit rotation
To guard against such a kickback, ptan your set-up
and direction of feed so that you will always be
thrusting the tool -- to hold it against whatever you
are using to guide the cut -- in the same direction
that the leading edge of the bit is moving In short,
the thrust should be in a direction that keeps the
sharp edges of the bit continuously biting straight
into new (uncut) wood
ROUTING
Whenever you are routing a groove, your travet
should be in a direction that places whatever guide
you are using at the right-hand side in short, when

the guide is positioned as shown in the first part of
Figure 9, tool travel should be left to right and
counterclockwise around curves. When the guide is
positioned as shown in the second part of Figure 9
tool travel should be right to left and clockwise
around curves, if there is a choice, the first set-up is
generally the easiest to use. In either case, the
sideways thrust you use is against the guide.
