the rotation forces of the spinning cutter will tend to throw

the trimmer away from the workpiece, causing kickback.

Because of the extremely high speed of cutter rotation dur-

ing a proper feeding operation, there is very little kickback

to contend with under normal conditions. However, should

the cutter strike a knot, hard grain, foreign object, etc. that

would affect the normal progress of the cutting action, there

will be a slight kickback. Kickback could be sufficient to

spoil the trueness of your cut if you are not prepared. Such

a kickback is always in the direction opposite the direction

of cutter rotation.

To guard against kickback, plan 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 cutter is

moving. The thrust should be in a direction that keeps the

sharp edges of the cutter continuously biting straight into

new (uncut) wood.
