with your hands on the infeed bed. When the piece
of wood is halfway through, reach around with
your left hand and steady the piece of wood on the
outfeed bed. Finish with both your hands on the
Never feed a piece of wood with your thumb
or finger against the end of the piece of
wood being fed into the jointer. Keep your
hands on top of the wood at all times.
Avoid jointing short pieces of wood
whenever possible. Joint a longer piece of
wood and then cut it to the desired size. If
you must joint a piece of wood shorter than
18 inches, use a push stick to feed it through
Never use a jointer with dull cutter blades.
Dull blades have a tendency to kick the
piece, and a kickback is always dangerous.
Keep the jointer table and the floor around
the jointer clear of scraps, chips, and
shavings. Always stop the jointer before
brushing off and cleaning up those scraps,
chips, and shavings.
Never joint a piece of wood that contains
Keep your eyes and undivided attention on
the jointer as you are working. Do not talk
to anyone while operating the jointer.
Remember, the jointer is one of the most
dangerous machines in the woodworking shop.
Only experienced and responsible personnel
should be allowed to operate it using the basic
safety precautions provided above.
A single surfacer (also called a single planer) is
shown in figure 3-11. This machine surfaces stock
on one face (the upper face) only. (Double
surfacers, which surface both faces at the same
time, are used only in large planing mills.)
The single surfacer cuts with a cutterhead like
the one on the jointer, but, on the single surfacer,
the cutterhead is located above instead of below
the drive rollers. The part adjacent to the
cutterhead is pressed down against the feed bed by
the chip breakers (just ahead of the cutterhead)
and the pressure bar (just behind the cutterhead).
The pressure bar temporarily
