OPERATION
FEATHERBOARD (FIG. PP, QQ)
A featherboard is a device used to help control the workpiece
by guiding it securely against the table or fence. Featherboards
are especially useful when ripping small workpieces and for
completing non-through cuts. The end is angled with a
number of short kerfs to give a friction hold on the workpiece
and locked in place on the table with C-clamps. Test that it
can resist kickback.
WARNING
Place the featherboard against the uncut
portion of the workpiece to avoid kickback that
could cause serious personal injury.
MAKE A FEATHERBOARD (FIG. PP)
Select a solid piece of lumber approximately 3/4 in. thick, 4 in.
wide and 18 in. long. To make a featherboard, cut one end of
the lumber at 60 degrees, then cut 8 in. long slots 1/4 in.
apart on the angled end as shown in Fig. PP.
USE A FEATHERBOARD (FIG. QQ)
WARNING
• Never feed wood with your hands
when making any non-thru cuts such as rabbets
or dadoes. To avoid personal injury, always use
push sticks (1), push blocks and featherboards.
• Do not locate the featherboard to the rear of the blade.
If positioned improperly, kickback can result from the
featherboard pinching the workpiece and binding the
blade in the saw kerf. Featureboards are not used
during non thru-sawing operations when using the
miter gauge. Failure to heed these warnings can result
in serious personal injury.
1. Lower the saw blade.
2. Position the rip fence (2) to the desired position and lock
the rip fence.
3. Place the workpiece (3) against the fence and over the saw
blade area.
