Resawing; Crosscutting - Powermatic 64S Operating Instructions And Parts Manual

RESAWING

1. Resawing is a ripping operation in which thick
boards are cut into thinner ones. Narrow boards up to
3" can be resawed in one pass. Wider boards up to 6"
must be resawed in two passes.
2. When resawing wider boards, adjust the saw
blade height so it overlaps the two cuts by 1/2" as
shown in Figure 36. Too deep of a first cut can result
in binding and kickbacks on the second cut. Always
place the same side of the board against the fence for
both cuts.

CROSSCUTTING

1. Crosscutting is a sawing process where the
workpiece is fed with the grain perpendicular to the
saw blade using the mitre gauge to support and posi-
tion the workpiece.
CAUTION: Do not crosscut workpieces
!
shorter than 6".
2. Before starting a cut, make sure that the mitre
gauge is securely clamped at the desired angle. Hold
the workpiece firmly against the table and back against
the mitre gauge as shown in Figure 37. 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 as shown in Figure 38. Length
stops should not be used on the free end of the
workpiece in the cutoff area.
4. For 90 o crosscutting, most operators prefer to
use the left-hand mitre 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, reverse the hand positions.
5. When using the mitre gauge, the workpiece must
be held firmly and advanced smoothly at a slow rate.
If the workpiece is not held firmly, it can vibrate caus-
ing it to bind on the saw blade and dull the teeth.
6. To improve the effectiveness of the mitre gauge
in crosscutting, some users mount an auxiliary wooden
extension face with a glued-on strip of sandpaper to
the gauge as shown in Figure 39.
7. Provide auxiliary support for any workpiece which
tends to sag and lift up off the table when it extends
beyond the table top.
