6. When used in normal horizontal position,
the stock feeder should be adjusted for
height so that the distance between the
table and the feed rollers is approximately
1/8” to 3/16” (3 to 5mm) less than the
thickness of the workpiece. See Figure 15.
Although the stock feeder
when properly used will greatly reduce the
chance of workpiece kickback, there is still a
potential for kickback. Never stand directly
in the path of the workpiece as it passes
under the Stock Feeder rollers.
When Used with a Shaper
1. The gap between the fences for the cutter
should be as small as possible.
2. To ensure that the workpiece is held firmly
against the fence, set the stock feeder at a
slight angle toward the fence in the direction
of feed. In other words, the outfeed roller
should be approximately 3/16” (5mm) closer
to the fence than the infeed roller. See
Figure 16.
3. When the Stock Feeder is in edgewise
position, it must be inclined slightly towards
the work table in the direction of feed, to
ensure the workpiece remains forced down
against the table. In other words, the
outfeed roller should be approximately 3/16”
closer to the work table than the infeed
roller. See Figure 17.
4. When the Stock Feeder is in the edgewise
position, or angled for a beveled workpiece,
the axis of the cutter should be between the
outfeed roller and the center roller. See
Figure 17. The center roller should NOT be
directed toward the opening between the
fences, but should act directly against the
fence.
5. When mounting the Stock Feeder in
edgewise position, keep in mind the spring
tension of the rollers. The distance between
the shaper fence and the feed rollers should
be approximately 1/8” to 3/16” (3 to 5mm)
less than the thickness of the workpiece
(refer to Figure 15).
6. Shaping hardwood with the Stock Feeder
may increase the friction between workpiece
and table. Keep the work table rust-free and
smooth, by using paste wax or other
necessary means.
