11.3 Hand placement
Never pass hands directly
over the cutterhead.
At the start of the cut, the left hand holds the
workpiece firmly against the infeed table and
fence while the right hand pushes the workpiece
in a smooth, even motion toward the cutterhead.
After the cut is under way, the new surface rests
firmly on the outfeed table. The left hand is
transferred to the outfeed side and presses
down on this part of the workpiece, at the same
time maintaining flat contact of workpiece with
fence. The right hand presses the workpiece
forward, and before the right hand reaches the
cutterhead it should be moved to the work on the
outfeed table.
It is strongly recommended that the provided
push block and push stick be used whenever
possible. See Figure 11-2. These are mandatory
when jointing smaller stock.

11.4 Surfacing
The purpose of surfacing (see Figure 11-2) on a
jointer is to produce one flat surface. The other
side can then be milled to precise, final
dimensions on a thickness planer resulting in a
board that is smooth and flat on both sides and
each side parallel to the other.

If the wood to be jointed is cupped or bowed,
place the concave side down, and take light
cuts until the surface is flat.

Never surface pieces shorter than 12 inches
or thinner than 3/8 inch without the use of a
special work holding fixture.

Never surface pieces thinner than 3 inches
without the use of a push block.

Cuts of approximately 1/16" or less at a time
are recommended, which provides for better
control over the material being surfaced.
More passes can then be made to reach the
desired depth.
11.5 Direction of grain
Avoid feeding work into the jointer against the
grain (Figure 11-3). This may result in chipped
and splintered edges.
Figure 11-3
Feed with the grain to obtain a smooth surface,
as shown in Figure 11-4.
