Powermatic pm1000 operating instructions Bevel and miter operations, Dado cutting

Length stops should not be used on the free end of the workpiece in the cutoff area.

Do not crosscut workpieces shorter than 6". Before starting a cut, be sure the miter gauge is securely clamped at the desired angle. Hold the workpiece firmly against the table and back against the miter gauge. Always use the saw guard and riving knife and make sure the riving knife is properly aligned.

For 90 degree crosscutting, most operators prefer to use the left-hand miter gauge slot. When using it in this position, hold the workpiece against the gauge with the left hand and use the right hand to advance the workpiece. When using the right hand slot for miter and compound crosscutting so that the blade tilts away from the gauge, the hand positions are reversed.

When using the miter gauge, the workpiece must be held firmly and advanced smoothly at a slow rate. If the workpiece is not held firmly, it can vibrate causing it to bind on the blade and dull the saw teeth.

Figure 38

To augment the effectiveness of the miter gauge in crosscutting, some users mount an auxiliary wooden extension face (F, Figure 38) with a glued- on strip of sandpaper (G) to the miter gauge.

Provide auxiliary support for any workpiece extending beyond the table top with a tendency to sag and lift up off the table.

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

10.5Bevel and miter operations

Bevel cut – A bevel cut is a special type of operation where the saw blade is tilted at an angle less than 90 degrees to the table top (Figure 39). Operations are performed in the same manner as ripping or crosscutting, except the fence or miter gauge should be used on the right-hand side of the blade to provide added safety in avoiding a binding action between blade and table top. When beveling with the miter gauge, the workpiece must be held firmly to prevent creeping.

Never use a zero-clearance insert with saw blade in tilted position.

Figure 39

Mitering – Crosscuts made at an angle to the edge of the workpiece are called miters (Figure 40). 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 40

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.

10.6Dado 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 41, is necessary for this type of operation.

Do not use the standard table insert for dadoing operations.
