EDGING wrrH A PILOT BIT

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.

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 -Lduces 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.
