1. BISCUIT SIZE SELECTION
As mentioned earlier, the three biscuit sizes are #0, #10 and #20.
It is a good rule of thumb to use the largest biscuit size that will
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 in a scrap piece. This is
extremely important as you do not want to discover during glue-up
that your biscuit slots are not quite deep enough.
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, you may have to 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
you can assemble the joint and trim off the exposed biscuit tip
after the glue sets (see Figure 13). 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, you may choose to use 2 biscuits across the thickness
for greater strength (see Figure 14). 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 15).
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 your
specific application.
