of the blade area such that the cutoff piece comes
free of the block before cutting begins.
Figure 9-8
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 9-9
To augment the effectiveness of the miter gauge in
crosscutting, some users mount an auxiliary wood
extension face (F, Figure 9-9) with a glued-on strip
of sandpaper (G) to help grip the workpiece.
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.
9.5 Bevel 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 9-10).
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.
insert with saw blade in tilted position.
Mitering – Crosscuts made at an angle to the edge
of the workpiece are called miters (Figure 9-11). 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.
