E. Glue, assemble and clamp the joint.
F. For stock thicker than 1", you may wish to use double biscuits at
each location. Set the height adjustment to allow at least 3/16" of
stock between the biscuit and the edge of the work surface. Make
all cuts at this fence setting before readjusting the fence for the
lower cuts. Again, there should be at least 3/16" of stock between
the biscuit and the outside surface and between the biscuits
themselves (see Figure 19).
2. FRAME JOINTS (SEE FIGURE 20)
Frame joints are an ideal application for biscuit joinery. With the plate
joiner you can create a very strong, precise joint that is much faster
to make than a dowel or mortise and tenon joint. Figure 20 shows two
types of frame joints. Follow the steps outlined below.
A. Arrange the workpieces on a flat work surface exactly as they are to
be assembled.
B. Select the proper biscuit size based on the length of the joint. (If the
frame pieces are too narrow for a #0 biscuit, you will have to allow the
biscuit tip to protrude slightly and then trim it off after the joint is dry
(see Figure 14).
C. Lay out the biscuit locations.
D. Set up the tool by selecting the depth that corresponds to the chosen
biscuit size. Lock the fence at 90° and adjust the fence height to
center the biscuit on the workpiece thickness.
E. Clamp the workpiece and position the Plate Joiner to make the first
cut (see Figure 21).
F. Turn on the tool and make the plunge cut.
G. Repeat for each layout mark.
H. Glue, assemble and clamp the frame.
3. CORNER JOINTS (SEE FIGURE 22)
Corner joints are another common and excellent application for
biscuit joinery. Follow the procedure below.
A. Arrange the workpieces exactly as they are to be joined.
