OPERATION
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 pul! router out of work and
place upside down on work surface before the
cutter stops.
EDGING WITH PILOT BITS
See Figure 14.
TOP EDGE SHAPING

GUIDE
WHOLE EDGE SHAPING Fig. U
Arbor-type bits with pilots are excellent for quick,
easy, edge shaping. They will follow workpiece edges
that are either straight or curved. 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 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 wili
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.
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.
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.
