physically fit in the application. Unless you are joining narrow face
or picture frames or using 1/2" or thinner stock, you will find the #20
biscuit size to suit most applications. After selecting the biscuit
size, set the depth adjustment knob to the corresponding size (see
Controls section). Also, be sure the fine depth adjustment is
correctly set by first testing the fit in a scrap piece. This is extremely
important to determine before glue-up.
2. BISCUIT LOCATION AND LAYOUT
Generally, biscuits may be spaced and located at your discretion.
For edge joints, a good rule of thumb is to space biscuits every 6-10
inches on center. It is further recommended that biscuits be placed
so that the centerline of the end biscuits is 2-3 inches from the end
of the workpiece. When joining face frames or picture frames where
the workpiece is narrow, choose the smaller biscuit sizes to keep
from "breaking out" on the end of the joint. Breaking out should be
avoided if possible, but if not assemble the joint and trim off the
exposed biscuit tip after the glue sets (see Figure 14). When
working with material up to 1" thick, we advise to use a single biscuit
located in the approximate center of the material thickness. If thicker
stock is to be joined, use 2 biscuits across the thickness for greater
strength (see Figure 15). Biscuit locations should be marked by
first positioning the mating pieces exactly as they are to be
assembled. Next, make a mark at 90° to the joint interface across
both pieces at the desired biscuit locations (see Figure 16). See
Application section for more specific information on joint layout. The
marks you make will then be aligned with one of the center
registration marks on the tool, again, depending upon the specific
application.

3. MAKING THE CUT

Prior to making any cut, be sure that all fence adjustments are set
and lock knobs are tight. Also, be sure you have selected the proper
depth setting. Clamp your workpiece firmly. Grasp the grip and
auxiliary handle and position the fence firmly and squarely against
the workpiece. Align the plate joiner's center registration mark with
