FEEDING
THE ROUTER (Fig. 13)
The secrets to professional-looking
routing are careful set-up for the cut, proper
depth-of
cut-selection,
knowing how the cutting
bit reacts in the workpiece,
and
the rate and direction
of feed of the router.
DIRECTION OF FEED: EXTERNAL CUTS (Fig. 13)
The router motor and cutting
bit rotate clockwise.
This
requires the feed of the cutting
bit to be from left to right (see
Fig. 13). Feeding the bit from
left to right will cause the bit
to pull the router towards (up
against) the workpiece.

If the router is fed in the

(right to

workpiece,
making it hard to
control. This is called "Climb-Cutting:"
cutting
in the opposite
direction
of the
proper feed direction.
"Climb
Cutting"
increases the chance of loosing control,
resulting
in possible
personal injury. When "Climb
Cutting"
is required (backing
around a corner, for example), exercise extreme caution to maintain control of
the router.

KICKBACK
Because of the high speed of the cutting
bit during a proper feeding operation
(left to right), there is very little kickback
under normal conditions.
However, if
the cutting
bit strikes a knot, an area of hard grain in the workpiece,
or a foreign
object,
the normal cutting action could be affected
and cause "Kickback."
This Kickback
may cause damage to your workpiece,
and could cause you to
lose control of the router, causing possible
personal injury. Kickback
is always
counterclockwise:
the opposite
direction
of the clockwise
cutting
bit rotation.
To guard against and help prevent
Kickback,
plan the set-up
and direction
of
feed so that the router is always moving, and keep the sharp edges of the cutting
bit continuously
biting straight
into new (uncut) wood (workpiece).
Also, always
inspect the workpiece
for knots, hard grain, and foreign objects that could cause
a kickback
problem.
