8. Make sure all fence lock handles are tight.
To set up the fence for partial edge removal,
do these steps:
1. Loosen the lock handles on the side of the
fence mount.
2. Turn the adjustment knob located on the
back of the fence mount and adjust the infeed
fence until the workpiece contacts the cutter
at the desired location.
3. Tighten the lock handle located on the side
of the fence mount to lock the fence into posi-
tion.
4. Adjust the outfeed fence so that it comes
into alignment with the infeed fence as shown
in figure 27.

5. Now place a straightedge against both faces
of the fence to check alignment. Once they
are both in alignment, make sure both lock
handles are tightened.
Always feed the wood against the rotation
of the cutter as shown in figure 28. Another
way to conceptualize this is to always feed the
wood into the cutter so that the cutter is push-
ing against the direction of feed.

Never feed wood in the same direction as the
cutter rotation. This is called a "climb cut" and
is extremely dangerous.
RUB COLLARS
When irregularly pieces are shaped, rub col-
lars are required. There are 2 types of rub col-
lars: solid and stand bags. They are available
in different diameters and may be purchased
individually or in sets, as shown in figure 33.
Examples of when to use a rub collar is with a

high arch or panels, round tables or other cut
that needs to have limited depth of cut. See
examples of adjustment.
There are 3 adjusting positions of rub collars:
1. On the cutter as
shown in figure 29.
This setting is the saf-
est and produces more
consistent results. The
only drawback is that
the court is on the un-
derside of the work
piece without the operator being aware of it,
however, if the work piece goes up from the
table, only one should run it second time to
complete the cut.
2. Between two cut-
ters as shown in figure
30. This adjustment
has the advantage of
making two cuts in
one pass.
Although it has a rub collar under the cutter,
this setting is safer than the before. Any lift-
ing of the work piece will cause an uneven cut.
With a second pass the uneven outline at the
bottom end will be corrected, but the upper
boundary will be rough because of the lifting
of the work piece into the cutter.
3. Below cutters as
shown in figure 31.
This setting will allow
the cut be supervised
by the operator; how-
ever, this setting is the
most dangerous.
Any lifting of the work piece would cause the
cutter to make a very deep cut. It also increases
the risk of recoil. Shaping with the rub collar
below the cutter is not recommended.
TOTALLY MANUAL CUTTING
The totally manual shaping is to shape without
the notch bevel or fence. The most dangerous
part of this operation is to start cutting where
the cutter makes the first contact with the
work piece. The work piece will often tend to
tap taking the operator unaware.
To reduce this tendency, use an starting pin,
this will help to anchor and slowly pivot the
work piece within the cutter to the initial cut-
