Figure 55 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. 

 

All butt-type joints require both work-pieces to be 
perfectly square and straight-edged. 

To perform a glue butt joint, both fences are kept 
inline and adjusted for a depth of cut (Figure 56). 

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. 

 

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 57. 

When shaping a drop-leaf joint as shown in 
Figure 58, 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 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 59. 

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.
