EDGING

WITH A PILOT

BIT (Figs.

14 and 14a)

The

arbor-type bits

with pilots

are excellent

for edge shaping

of any

workplace

edge

that

Is

either

straight,or

curved

at e curvatureas great or

greater

than

the

radiusof the

bit to

be used,The ptlotprevents

the

bit from

making

too deep s cut;

and

holdtngthe pilot

firmly

In contactwith theworkpfecaedge

throughout

prevents

the

cut from

becoming too

shallow,

Whenever

the

workptsca

thickness,

togetherwith the deslrad depth ofcut (as adjusted by

router depth setting)are such that only the top part of

the

Edge

is to be shaped (leaving

at

least

a 1/164n+thlsk

uncut

portion

at

the

bottom), the pilot

can dds

against the

uncut

portion,which serves to

guide

It(see Fig, 14),

If theworkplace

Is

too thinor

the

blt set too fewso that there will be no uncut

Edge

to

ride

the pilotagainst,

an_xtra

boardto

act as

a guide mustbe placed underthe workplace

(see Fig.

14a), This

guide"

board

must

have exactly

the same contour-

straight or

curved

-

as the

workplace edge. If It is positionedso that its edge isflush with

the

workplaceedge,

the

bit

will make a

full

cut (In

as far EB

the

bit radius), On the

other

hand, If

the

guide Is

positioned as

shown

In

Flg.

14a

(out from the workplace edge), the bitwill

rr_ke tess than

a fullcut- whichwill alter the shapeof the

flntshed

edge,

NOTE:

The

size (diameter)

of the pilot

that

ls

used

determines

the maximum

cut

width

that

can

be

made

with

the pilot against

the workplace

edge

(the

small

pilot

exposes

all of the bit;

the

large

one reduces

this

amount

by 1/16-fn,).

Any

of

the

piloted

cutter

bits can

be used without

a

pilot

for edge

shaping

with

guides,
