Figure 58 shows BOTH cuts required for a window
sash rail end. The first operation at top is a rabbet
cut made with a groove cutter. The second
operation is performed with a stub spindle and
buttonhead screw.
Butt Joints
All butt-type joints require both work-pieces to be
perfectly square and straight-edged.
Glue Butt Joint
To perform a glue butt joint, both fences are kept
inline and adjusted for a depth of cut (Figure 59).
The cuts on both work-pieces are part-edge cuts
which do not reduce the stock width during the
cutting procedure. When shaping the two
workpieces, one is fed top-side up; the other is fed
bottom-side up.
Tongued Joint
Similar to the glue joint, both fences are kept in-line
for the tongued joint and adjusted for a 1/4 inch
depth of-cut with no reduction in stock width. With
this joint, however, both work-pieces are fed with
the same side up as shown in Figure 60.
Drop Leaf Joint
When shaping a drop-leaf joint as shown in
Figure 61, the leaf workpiece is shaped with a
Drop-Leaf Bead cutter; the table workpiece is
shaped with a Drop-Leaf Cove cutter.
With this type joint, the whole edge of both
workpieces is shaped, same-side up, and
allowance made for a 1/16 inch reduction in width.
Adjust the in-feed fence to reduce the workpiece
width by 1/16 inch, and adjust the out-feed fence to
compensate for stock removed.
Taper Cuts
Taper cuts can be made by offsetting the fences
for the amount of taper desired, or with a layout
line on the stock which can be paralleled to the
infeed fence as shown in Figure 62.
Start the cut by holding the stock against the
infeed fence and swinging it into contact with the
outfeed fence just past the cutterhead. As the cut
is started, transfer pressure to hold the workpiece
against the outfeed fence, and continue feeding
the workpiece through. After the first cut, the
fences will have to be readjusted in order for the
second cut (parallel cut) and the final depth-of-cut
to remain true with the taper.

Do not use the standard fence
for short work (12 inches or less in length on
the side to be cut). Instead, use a miter gauge
or special fixture to avoid losing control of the
workpiece.
