OPERATION
Whenever you are shaping an edge, the feed should
always be clockwise when working on an outside
(convex) edge; but should be counterclockwise
when working on an inside (concave) edge. See Fig.
11. The reason for this is that, when traveling the tool
as instructed, the bit will have a "chopping action"
but will have a "gouging a, c tion" If you reverse the
travel direction. "Chopping is much preferable to
"gouging" as there Is less danger of ripping, out
chips by tearing the wood grain.

STARTING AND ENDING A CUT
INTERNAL ROUTING
Tilt Router and place on workplece, letting edge of
subbase contact workpiece first. Be careful not to let
Router bit contact workpieee. Turn Router on and let
motor build to Its full speed. Gradually feed cutter in-
to workpiece until subbase Is level with workplece.
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 MOTOR STOPS.
EDGE ROUTING
Place Router on workplece, making sure the Router
bit does not contact workpiece. Turn Router on and
let motor build to Its full speed. Begin your out,
gradually feeding cutter into workpiece. WARNING:
KEEP A FIRM GRIP ON ROUTER WITH BOTH
HANDS AT ALL TIMES, FAILURE TO DO SO COULD

ING: NEVER PULL ROUTER OUT OF WORK AND

EDGING WITH THE PILOT BITS
The arbor-type bits with pilots are excellent for
quick, easy edge shaping of any worl<piece 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 malting 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 set.
ting) are such that only the top part of the edge is to
be shaped (leaving at least a 1/16 in. thick uncut por-
tion at bottom), the pilot can ride against the uncut
portion, which will serve to guide it. See Fig. 12.
However, if the workpiece is too thin and/or the bit
set too low so that there will be no uncut edge to ride
the pilot against, any 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
workplece 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 Fig, 12 (out from the
workpiece edge), the blt will make less than a full out
-- 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 pl!ot ex-
poses all of the bit; the large one reduces this
amount by 1/16 inch).
