Dado cutting | Powermatic 64B manual

Figure 41

Mitering – Crosscuts made at an angle to the edge of the workpiece are called miters (Figure 42). Set the miter gauge at the required angle, and make the cut the same as a normal crosscut except the workpiece must be held extra firmly to prevent creeping.

Figure 42

Note: When making compound miters (with blade tilted) use the miter gauge in the right hand slot to provide more hand clearance and safety.

Have the blade extend only 1/8" above the top of the workpiece. Exposing the blade above this point can be hazardous.

11.7Dado cutting

Dadoing is cutting a wide groove into a workpiece or cutting a rabbet along the edge of a workpiece. A dado insert (optional accessory, not provided) shown in Figure 43, is necessary for this type of operation.

Do not use the standard table insert for dadoing operations.

Figure 43

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 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.

The guard, riving knife, and anti-kickback pawls supplied with the saw should be used for all cutting operations where they can be used. When performing operations where the 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 appropriate device that can be utilized to keep operators’ hands away from the blade. Upon completion of the operation requiring removal of the guard, the entire guard assembly must be placed back on the machine in its proper working order.

Never use a dado head in a tilted position. Never operate the saw without the blade guard, riving knife and anti-kickback pawls for operations where they can be used.
