EDGING WITH THE 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 workptece
edge throughout prevents fhe cut from becoming
too shallow
Whenever the workplece thickness together with the
desired depth of cut (as adjusted by router depth set.
ting) are such that only the tap 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 Figure !0.
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 workplace This "guide" board
must have exactly the same contour -- straight or
curved -- as the workptece edge If tt 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 10 (out from the workpieca 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

size (diameter) of the pilot that {s used determines
the maximum cut width that can be made with the
pilot against the workpiece edge (the small pilot ex-
poses all of the bit; the large one reduces this
amount by 1/16 inch)
