9.3 Resawing
Resawing is a ripping operation in which thick
boards are cut into thinner ones. Narrow boards up
to 3" can be resawn in one pass. Wider boards up
to 6" must be resawn in two passes.
In resawing wider boards, adjust the blade height
so as to overlap the two cuts by 1/2" as shown in
Figure 9-7. Too deep a first cut can result in
binding and possible kickbacks on the second cut.
Always use the same side of the board against the
fence for both cuts.

9.4 Crosscutting
Crosscutting is where the workpiece is fed cross
grain into the saw blade using the miter gauge to
support and position the workpiece (Figure 9-8).
Crosscutting should never be done freehand nor
should the fence be used as an end stop unless an
auxiliary block (A, Figure 9-9) is clamped to the
front of the blade area such that the cutoff piece
comes free of the block before cutting starts.
Figure 9-8
Figure 9-9
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.
To improve the effectiveness of the miter gauge in
crosscutting, some users mount an auxiliary
wooden extension face (A, Figure 9-10) with a
glued-on strip of sandpaper (B) to the miter gauge.
