bit withthebushingbeforebeginning your cut, Your
router subbase may be adjusted by loosening the
screws holding the subbase to your router, Be sure to
tighten locking arm before centering bit in bushing,
After centering bit with bushing, tighten screws
securely,
EDGING WiTH PILOT BiTS
See Figure17,
Arbor-type bits withpilots a reexcellent f orquick,
easy,edge shaping, They will f ollow workpieceedges
thatareeither straight or curved, The pilot p revents
thebit from making toodeep a cut;and holding the
pilot f irmly incontact withtheworkpieceedge
throughout prevents thecutfrom 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 17,
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 17 (out from the workpiece 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
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,
