OPERATION
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.
I
Upon completion of cut, turn motor off and let it come to
complete stop before removin_grouter from work surface.
Never pull router out of work and place upside down on
work surface before the cutter stops.
EDGING WITH PILOT BITS
See Figure 20.
Rabbets and molded edges can be cut using piloted cutters.
The pilot extends below the cutter. Some pilots are solid
extensions of the cutter. Others are ball bearing guides that
are fastened to the end of the cutter. The pilots allow the
cutters totum while the pilot follows the edge ofthe workpiece.
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 wo rkpiece 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 20. 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
20 (out from the workpiece edge), the bit will make less than
a full cut -- which will alter the shape of the finished edge.
NOTE: If desired, any of the piloted bits can be used without
a.pilot for edge shaping with guides, as preceding. Also, the
stze (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).

away from the end. Feed the cutter into the wood untilthe pilot
contacts the uncut edge. Then, slowly back the router to
shape the corner. Next, move the router forward to shape the
rest of the edge. Be careful to keep the pilot pressed against
the uncut edge. Repeat this procedure on each side of the
panel. Figure 21 shows the proper sequence of cutsto make
when edge routing four sides of a panel.
