Resawing
1. 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.
2. In resawing wider boards, adjust the blade
height so as to overlap the two cuts by 1/2"
(Figure 40). Too deep a first cut can result
in binding and kickbacks on the second cut.
Always use the same side of the board
against the fence for both cuts.
Crosscutting
1. Crosscutting is a sawing process where the
workpiece is fed cross grain into the saw
blade using the miter gauge to support and
position the workpiece.
Do not crosscut workpieces
shorter than 6".
2. Before starting a cut, be sure that the miter
gauge is securely clamped at the desired
angle. Hold the workpiece firmly against the
table and back against the miter gauge as
shown in Figure 41. Always use the saw
guard and splitter and make sure the splitter
is properly aligned.
3. Crosscutting should never be done freehand
nor should the fence be used as an end stop
unless an auxiliary block is clamped to the
front of the blade area such that the cutoff
piece comes free of the block before cutting
starts (Figure 42). Length stops should not
be used on the free end of the workpiece in
the cutoff area.
4. 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 crosscutting using the
right hand slot, the hand positions are
reversed.
5. 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.
6. To improve the effectiveness of the miter
gauge in crosscutting, some users mount an
auxiliary wooden extension face with a
glued-on strip of sandpaper to the gauge
(Figure 43).
