One of the most useful jointer operations is
cutting an edge to a taper. This method can be
used on a wide variety of work; tapered legs of
furniture is a common example.
Instead of laying the piece down on the infeed
table, lower the forward end of the work onto the
outfeed table.
Use caution, however, as the
piece will span the knives, and they will take a
"bite" from the work with a tendency to kick back
unless the piece is held firmly. Push the work
forward as in ordinary jointing. The effect is to
plane off all the stock in front of the knives to an
increasing depth, leaving a tapered surface.
The ridge left by the knives when starting the
taper may be removed by taking a very light cut
in the regular jointing procedure, with the infeed
table raised to its normal position.
Practice is required in this operation. Beginners
are advised to make trial cuts with scrap
material.

Note: Rabbet cuts are not applicable with the
Model JJ-8HH Jointer with helical head.
1. Adjust the fence so that the distance
between the end of the knives and fence is
equal to the width of the rabbet (Fig. 28).
2. Lower the infeed table an amount equal to
the depth of the rabbet. If the rabbet is quite
deep, it may be necessary to cut in two or
more passes.
3. In that event, the table is lowered an amount
equal to about half the depth of the rabbet
for the first pass, then lowered again to
proper depth to complete the cut.
