OPERATION cutting aids See Figure 41. Push sticks are devices used for safely pushing a workpiece through the blade. They can be made in various sizes and shapes from scrap wood to use in a specific project. The stick must be narrower than the workpiece, with a 90˚ notch in one end and shaping for a grip on the other end. A push block has a handle fastened by recessed screws from the underside. Be sure the screw is recessed. Use it on non-through cuts. AUXILIARY FENCE An auxiliary fence is a device used to close the gap between the rip fence and the saw table. Always make and use an auxiliary fence when ripping material 1/8 in. or thinner. How to Make and ATTACH an auxiliary fence (for rip cutting thin workpiece) See Figure 42. An auxiliary fence may be made for the saw by cutting a piece of wood to 3/4 in. thick, 3-1/2 in. wide, and 31 in. long. To attach the auxiliary fence to the rip fence:  Drill two countersunk holes in the locations shown. WARNING: When mounting an auxiliary fence face, position mounting hardware beyond arrows at right and left. Keep fasteners away from blade.  Slide two T-bolts (not included) into the rip fence groove beyond the arrows at right and left of the label on the rip fence.  Match the T-bolts to the holes in the auxiliary fence and secure it to the rip fence with a washer and nut.  Ensure that the auxiliary fence is securely attached before use. How to Make a jig (for rip cutting narrow workpiece) See Figure 43. If ripping a narrow workpiece places the hands too close to the blade, it will be necessary to make and use a jig. To make a jig:   Attach a handle to a long, straight piece of wood and secure from the underside using recessed screws.   Cut an L-shaped stop in the side of the jig. To use a jig:   Position the workpiece flat on the table with the edge flush against the jig and against the stop.   Holding the jig handle and using a push block, make the rip cut as described later in this section.

PUSH STICKS
CUTTING AIDS
See Figure 41.
Push sticks are devices used for safely pushing a workpiece
through the blade. They can be made in various sizes and
shapes from scrap wood to use in a specific project. The
stick must be narrower than the workpiece, with a 90˚ notch
in one end and shaping for a grip on the other end.
A push block has a handle fastened by recessed screws
from the underside. Be sure the screw is recessed. Use it
on non-through cuts.
AUXILIARY FENCE
An auxiliary fence is a device used to close the gap between
the rip fence and the saw table. Always make and use an
auxiliary fence when ripping material 1/8 in. or thinner.
HOW TO MAKE AND ATTACH AN AUXILIARY
FENCE (FOR RIP CUTTING THIN
WORKPIECE)
See Figure 42.
An auxiliary fence may be made for the saw by cutting a
piece of wood to 3/4 in. thick, 3-1/2 in. wide, and 31 in. long.
To attach the auxiliary fence to the rip fence:
Drill two countersunk holes in the locations shown.
WARNING:
When mounting an auxiliary fence face, position
mounting hardware beyond arrows at right and
left. Keep fasteners away from blade.
Slide two T-bolts (not included) into the rip fence groove
beyond the arrows at right and left of the label on the rip
fence.
Match the T-bolts to the holes in the auxiliary fence and
secure it to the rip fence with a washer and nut.
Ensure that the auxiliary fence is securely attached before
use.
HOW TO MAKE A JIG (FOR RIP CUTTING
NARROW WORKPIECE)
See Figure 43.
If ripping a narrow workpiece places the hands too close to
the blade, it will be necessary to make and use a jig.
To make a jig:
Attach a handle to a long, straight piece of wood and
secure from the underside using recessed screws.
Cut an L-shaped stop in the side of the jig.
To use a jig:
Position the workpiece flat on the table with the edge
flush against the jig and against the stop.
Holding the jig handle and using a push block, make the
rip cut as described later in this section.
