NOTE: When tilting the Fence Body past the
Fixed Plate (43B), the Stop Block (44B) must be
moved out of the way.
4. The Fence Segment (39B) features positive
stops at the most used fence positions of 90 de-
grees and 45 degrees, right and left. Check the
Fence Body (4B) with a square to make sure the
fence is 90 degrees to the Front Table (2B) and
Rear Table (3B). If an adjustment is necessary,
loosen the Screw (47B). Turn the Screw in or
out against the Stop Block (44B) until the Fence
Body is at 90 degrees to the Front Table and
Rear Table. Then, retighten the Screw. Follow
this same procedure to check the positive stops
at 45 degrees, right and left.
PLACEMENT OF HANDS DURING FEEDING
At the start of the cut, the left hand holds the
work firmly against the front table and fence,
while the right hand pushes the work toward
the knives. After the cut is under way, the new
surface rests firmly on the rear table as shown
in figure 16.
Rear
table
The right hand pushes the work forward and
before the right hand reaches the cutterhead it
should be moved to the work on the rear table.
NEVER PASS HANDS DIRECTLY OVER THE CUT-
TERHEAD.
JOINTING AN EDGE
This is the most common operation for the
jointer, set the guide fence square with the
table. Depth of cut should be the minimum
required to obtain a straight edge, hold the
best face of the piece firmly against the fence
throughout the feed.
JOINTING WARPED PIECES
If the wood to be jointed is dished or warped,
take light cuts until the surface is flat. Avoid
forcing such material down against the table;
excessive pressure will spring it while passing
the knives, and it will spring back and remain
curved after the cut is completed.

JOINTING SHORT OR THIN WORK
When jointing short or thin pieces, use a push
block to eliminate all danger to the hands.
Two types are
shown in figure
17 they are easily
made from scrap
material.

DIRECTION OF GRAIN
Avoid feeding work into the jointer against
the grain as shown in figure 18, the result will
be chipped and splintered edges.
Feed with the grain as in figure 19 to obtain a
smooth surface.

BEVEL
To cut a bevel, lock the fence at the required
angle and run the work across the knives while
keeping it firmly against the fence and table,
several passes may be necessary to arrive at,
the desired result.
When the angle is small, there is little differ-
ence whether the fence is tilted to the right or
left, however, at greater angles approaching
45 degrees, it is increasingly difficult to hold
the work properly when the fence is tilted to
the right. The advantage of the double tilting
fence is appreciated under such conditions.
When tilted to the left, the fence forms a v-
shape with the tables, and the work is easily
pressed into the pocket while passing it across
the knives. If the bevel is laid out on the piece
in such direction that this involves cutting
against the grain, it will be better to tilt the
fence to the right.
TAPER CUTS
One of the most useful jointer operation is cut-
ting an edge to a taper. The method can be
used on a wide variety of work. Tapered legs
of furniture are a common example. Instead of
laying the piece on the front table, lower the
forward en of the work onto the rear table.
Do this very carefully as the piece will span the
knives, and they will take a "bite" from the
