Bevel & Mitre Operations; Dado Cutting - Powermatic 66 Instruction Manual & Parts List

6. Stop rods can be used in the holes provided in
the mitre gauge for repetitive work of equal length.
Do not use a stop rod on the free end of a workpiece.
It should be used on the side of the mitre gauge op-
posite the saw blade.
7. Have the blade extend about 1/8" above the
top of the workpiece. Exposing the blade above this
point can be hazardous.
BEVEL & MITRE OPERATIONS
1. A bevel cut is a special type of operation where
the saw blade is tilted at an angle less than 90 de-
grees to the table top. See Figure 32. Operations
are performed in the same manner as ripping or
crosscutting except the fence or mitre gauge should
be used on the right-hand side of the saw blade to
provide added safety in avoiding a binding action be-
tween the saw blade and the table top. When bevel-
ing with the mitre gauge, the workpiece must be held
firmly to prevent creeping.
2. Crosscuts made at an angle to the edge of the
workpiece are called mitres. See Figure 33. Set the
mitre gauge at the required angle, lock the mitre
gauge, and make the cut the same as a normal cross-
cut except the workpiece must be held extra firmly
to prevent creeping.
NOTE: When making compound mitres (with blade
tilted) use the mitre gauge in the right hand slot to
provide more hand clearance and safety.
3. Have the blade extend only 1/8" above the top
of the workpiece. Exposing the blade above this point
can be hazardous.

DADO CUTTING

Dadoing is cutting a wide groove into a workpiece or
cutting a rabbet along the edge of a workpiece. A
dado insert, shown in Figure 34, is necessary for this
type of operation.
CAUTION: Do not use the standard table
!
insert for dadoing operations.
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. By using various combinations of
the stacked dado blades, or properly setting the dial
on an adjustable blade, an accurate width dado can
be made. This is very useful for shelving, making
joints, tenoning, etc.
