Figure 9-2
Always use blade guard, splitter/riving knife and
anti-kickback pawls. Make sure splitter/riving knife
is properly aligned. When wood is cut along the
grain, the kerf tends to close and bind on the blade
and kickbacks can occur.
Note: A warning decal is affixed to the guard to
remind the operator of some basic safety
procedures.
The rip fence should be set for the width of the cut
by using the scale on the front rail, or by measuring
the distance between blade (A) and fence (B).
Stand out of line with saw blade and workpiece to
avoid sawdust and splinters coming off the blade or
a potential kickback.
If the workpiece does not have a straight edge, nail
an auxiliary straight edged board on it to provide
one against the fence. To cut properly, the board
must make good contact with the table. Do not
attempt to cut warped boards.
Figure 9-3
In ripping, use one hand to hold the board down
against the fence or fixture, and the other to push it
into the blade between blade and fence. If
workpiece is narrower than 6" or shorter than 12",
use a push stick or push block to push it through
between fence and blade (Figure 9-4). Never push
in a location such that the pushing hand is in line
with the blade. Move the hand serving as a hold-
down a safe distance from blade as cut nears
completion.
For very narrow ripping where a push stick cannot
be used, use a push block or auxiliary fence.
Always push the workpiece completely past the
blade at the end of a cut to minimize the possibility
of a kickback.
Figure 9-4
Figure 9-5
When ripping long boards, use a support at front of
table (C, Figure 9-5), such as a roller stand, and a
support or "tailman" at the rear (D).
Never use the rip fence beyond the point where the
carriage is flush with the end of the rails.
Have the blade extend about 1/8" above top of
workpiece. Exposing the blade above this point can
be hazardous.
9.3 Resawing
Resawing is a ripping operation in which thick
boards are cut into thinner ones. Note: A band saw
is the ideal tool for resawing.
If the table saw is used for
resawing, take precautions such as using an
auxiliary fence, resaw barrier or similar devices
to stabilize the workpiece and provide operator
safety.
Narrow boards up to 3" can be resawn in one pass.
Wider boards up to 6" must be resawn in two
passes.
