STARTING AND ENDING A CUT
INTERNAL ROUTING
Tilt router and place on workpiece, letting edge of subbase
contact workpiece first. Be careful not to let router bit contact
workpiece. Turn router on and let motor build to its full speed.
Gradually feed cutter into workpiece until subbase is level
with workpiece.
WARNING:
Keep a firm grip on router with both hands at all times.
Failure to do so could result in loss of control leading to
possible serious injury.
Upon completion of cut, turn motor off and let it come to a
complete stop before removing router from work surface.
WARNING:
Never pull router out of work and place upside down on
work surface before the cutter stops.
EDGING WITH PILOT BITS
The arbor-type bits with pilots are excellent for quick, easy,
edge shaping of any workpiece edge that is either straight or
curved at a curvature as great or greater than the radius of
the bit to be used. The pilot prevents the bit from making too
deep a cut; and holding the pilot firmly in contact with the
workpiece edge throughout prevents the cut from becoming
too shallow.
Whenever the workpiece thickness together with the desired
depth of cut (as adjusted by router depth setting) are such
that only the top part of the edge is to be shaped (leaving at
least a 1/16 inch (1.6 mm) thick uncut portion at bottom), the
pilot can ride against the uncut portion, which will serve to
guide it. See Figure 14. However, if the workpiece is too thin
or the bit set too low so that there will be no uncut edge to ride
the pilot against, an extra board to act as a guide must be
placed under the workpiece. This "guide" board must have
exactly the same contour— straight or curved—as the
workpiece edge. If it is positioned so that its edge is flush with
the workpiece edge, the bit will make a full cut (in as far as
the bit radius). On the other hand, if the guide is positioned
as shown in Figure 14 (out from the workpiece edge), the bit
will make less than a full cut — which will alter the shape of
the finished edge.
NOTE: Any of the piloted bits can be used without a pilot for
edge shaping with guides, as preceding. The size (diameter)
of the pilot that is used determines the maximum cut width
that can be made with the pilot against the workpiece edge
(the small pilot exposes all of the bit; the large one reduces
this amount by 1/16 inch (1.6 mm).

EDGE ROUTING
Place router on workpiece, making sure the router bit does
not contact workpiece. Turn router on and let motor build to
its full speed. Begin your cut, gradually feeding cutter into
workpiece.
Keep a firm grip on router with both hands at all times.
Failure to do so could result in loss of control leading to
possible serious injury.
Upon completion of cut, turn motor off and let it come to a
complete stop before removing router from work surface.
Never pull router out of work and place upside down on
work surface before the cutter stops.
