Bevel Cut
To cut a bevel, lock the fence at the desired
angle and run the material through,
pressing the work firmly against the fence
and tables (Fig. 31). Several passes may
be necessary for the desired result.
Taper Cut
Taper cuts require the
removal of the cutterhead guard. Use
extreme caution when making taper cuts
and replace the guard immediately
after
completion! Failure to comply may
cause serious injury!
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.
Rabbet Cut
Rabbeting requires the
removal of the cutterhead guard. Use
extreme caution when making rabbeting
cuts and replace the guard immediately
after completion!
Failure to comply may
cause serious injury!
Note: Rabbet cuts are not applicable with
the Model JWJ-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. 32).

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.
