Shaping

Many shaping operations involve

the removal of the entire edge of a

square piece of stock as it is

moved past the cutter. With a

careful offset fence setup, a

shaping operation can

simultaneously straighten or joint

the shaped edge. Hereʼs how:

Install router bit

Set desired depth of cut

Adjust fence gap as

necessary

See Gap Adjustment on page 12.

Set initial fence

position

Unlock the carriage clamp and

slide the fence up to the cutter.

Adjust the location of the fence to

position the outfeed fence in line

with the outermost cutting arc of

the smallest diameter on the cutter,

Fig. 29. A thin straightedge held

against the outfeed fence can be

used to help align the fence with

the smallest diameter of the cutter.

Fig. 30

Set the desired fence

offset

Set the desired fence offset by

adjusting the infeed fence

backward. (See Infeed Fence

Adjustment on page 10.)  Moving

the infeed fence back about .015”
