The secret to professional rout­

ing is in making a careful set-up

for the cut, selecting the proper
depth of cut, knowing how the
cutting bit reacts in your work
piece, and the rate and direc­

tion of feed of the router.

DIRECTION OF FEED - EX­

TERNAL CUTS (Fig. 16)

The router motor and cut­
ting bit rotate clockwise. This
requires the feed of the cutting
bit to be from left to right (see
Fig, 16). Feeding the bit from
left to right will cause the bit to pu

If you feed the router in the opposite direction (right to left), the rotating force of the

cutting bit will tend to throw the bit away from the work piece, making it hard to
control; this Is called Climb-Cutting, which is cutting in tije opposite direction of the
proper feed direction. Climb Cutting increases the chance for loss of control, pos­
sibly resulting in personal injury. When Climb Cutting is required (backing around a

corner for example), exercise extreme caution to maintafo control of the router.

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 wood work piece, or a

foreign object, the normal cutting action could be affected and cause “Kickback.”

This Kickback may cause damage to your work piece, and could cause you to

lose control of the router, causing possible personal injury. Kickback is always in

the opposite direction of the clockwise cutting bit rotatran, or counterclockwise.

To guard against and help prevent Kickback, plan your set-up and direction of
feed so you’re always moving the router, keeping the sharp edges of the cutting

bit continuously biting straight into new (uncut) wood (vyork piece). Also, always
inspect your work piece for knots, hard grain, and foreign objects that could

cause a kickback problem.
