Edge
Rabbeting

The width of the edge rabbet will be the distance from
the outer corner of the knives to the fence.

Edge rabbeting
is the process of removing part of the thickness of the stock
along an edge to produce a lip or tongue. It's a fast and
accurate way of making strong, interlocking corner joints
or for recessing a panel into a frame.
To set
up to cut an edge rabbet, first unplug the machine. Check
that the knives are evenly adjusted from side-to-side and
that they extend 1/32" beyond the left side of the outfeed
table. Warning: If the knives aren't properly positioned,
the stock may not clear the side of the outfeed table when
the cut is made. Pull the fence lock handle out, unlock
the fence, and move it toward the left side of the table (away
from the drive shaft). The width of the rabbet will be the
distance from the outer corner of the knives to the fence
(Figure 6-23).
When you're satisfied that the setup is correct, lock the
fence in place.

Use the fence extension to provide support when cutting
an end rabbet.

Your jointer
will cut rabbets up to 3/8" deep, but never try to remove
more than 1/8" of stock in a single pass. For deeper cuts,
begin with the depth of cut set at 1/8"; then increase it
after each pass. If you're making several rabbets to match,
machine all pieces at each setting before changing the depth
of cut.
When cutting
end rabbets (Figure
6-24), there is a tendency for wood to split out or splinter
at the end of the cut. As with end grain jointing, splintering
can be reduced by taking very light cuts and by feeding the
stock more slowly. You can also use a utility knife or chisel
to score the wood fibers before rabbeting.

When you need rabbets, tongues, or tenons on narrow
pieces, do the work on pieces of stock wide enough to
be safely handled and then rip them on the table saw.

Follow
the pattern illustrated in Figure
6-25 when you need rabbets, tongues, or tenons on narrow
stock. After using the jointer, use the table saw to rip the
material into correct widths. Warning: Never try to rabbet
stock which will have less than 10" of support against the
tables and fence or a piece so narrow that your hands will
cross into the danger zone.
