Bevel And Mitre Operations; Dado Cutting - Powermatic 64S Operating Instructions And Parts Manual

8. Adjust the saw blade height so it extends about
1/8" above the top of the workpiece. Raising the saw
blade above this point increases the risk of injury.

BEVEL AND MITRE OPERATIONS

1. A bevel cut is a special type of operation where
the saw blade is tilted at an angle less than 90
table top. Beveling is done in the same manner as
ripping or crosscutting. When beveling with the mitre
gauge, the workpiece must be held firmly to prevent
creeping as shown in Figure 40.
2. Crosscuts made at an angle to the edge of the
workpiece are called mitres. Set the mitre gauge to
the required angle and lock it. Make the cut the same
as a normal crosscut except hold the workpiece tightly
to prevent creeping as shown in Figure 41.
3. Adjust the saw blade height so it extends about
1/8" above the top of the workpiece. Raising the saw
blade above this point increases the risk of injury.

DADO CUTTING

The process of cutting 1/8" to 13/16" grooves in
workpieces is accomplished by the use of a stacked
dado blade set or an adjustable type blade mounted
on the saw arbor.
1. By using various combinations of the stacked
dado blades, or properly setting the dial on an adjust-
able blade, an accurate width dado can be made. This
is very useful for shelving, making joints, tenoning, etc.
The guard, splitter and anti-kickback pawls supplied
with the saw should be used for all cutting operations
where they can be used. When completing operations
where the supplied guard cannot be used as in some
dadoing operations, alternative safety precautions
should be taken. These include: push sticks, feather
boards, filler pieces, fixtures, jigs and any other ap-
propriate device that can be utilized to keep opera-
tors' hands away from the blade. See page 27.
2. Upon completion of the operation requiring re-
moval of the guard, the entire guard assembly must
be placed back on the machine in its proper working
position.
CAUTION: Never use a wedge between
!
the arbor collar and saw blade to create a
"wobble" dado. Never operate the saw
without the guard, splitter and anti-kickback
pawls for operations where they can be
used. Never use a dado head in a tilted
position.
