EDGING wrrH A PILOT BIT (Figs, 15 and 15a)
Arbor-type bits with pilots
are excellent for edge shap-
ing any work-piece edge that
is straight or is curved at a
curvature that is equal to or
greater than the bit radius.
The pilot prevents the bit from
making too deep a cut. Hold-
ing the pilot firmly in contact
with the work-piece edge
prevents the cut from becom-
ing too shallow.
Used when the thickness of
the work piece and the depth
of cut are such that only
the top part of the edge is
shaped, and at least 1/16 in.
of the lower part of the work
piece remains uncut, the pilot
rides against and is guided by
the uncut portion (Fig. 15).
An extra board must be
placed under the work piece
to act as a guide if less than
!/16-inch of the work piece
would otherwise remain un-
cut-either because the work
piece is too thin or the bit is

set too low (see Fig. 15a)o This guide board must have exactly the same contour
r
- straight or curved - as the work-piece edge. If the guide board is positioned so
I
that it extends from the work piece, the bit will make less than a full cut, which will
alter the shape of the finished edge
NOTE: The size (diameter) of the pilot determines ti_e maximum cut width
that can be made (the small pilot exposes all of the bit; the large one re -L
duces this amount by 1/16 in.). Any of the piloted cutting bits can be used
without a pilot, but with a guide, for edge shaping.,
_t_ WARNING: Always securely clamp your work piece and keep a firm grip
on the router base with BOTH HANDS at all times. _ailure to do so could
result in loss of control causing possible serious personal injury.
