"T" JOINT
B. Layout biscuit locations on the inside of the angle.
C. Set up tool by setting fence angle to 45°. Set vertical fence
adjustment so that the biscuit is located toward the inside of
the joint where material is thicker. Select biscuit size so that
the blade does not protrude through the outside face of
the material.
D. Clamp the workpiece and align the tool as shown in Figure 29.
E. Make the plunge cut and repeat for all biscuit locations.
F. Glue, assemble and clamp the joint.
G. For joints other than 90° see inside registration column in
Figure 28 for proper fence angle setting.
6. T-JOINTS (Figure 30)
Biscuit joining is a viable alternative to dadoing when making a
T-joint. T-joints are most commonly used when attaching shelves
to the sides of a case. The method described below will work if your
shelf material is at least 5/8" thick.
A. Place the workpieces on a work surface exactly as you will be
assembling them in the form of an upside down "T." Mark
lightly along the joint where the top of the shelf is to end up
(see Figure 31). Mark biscuit locations at the joint interface on
the shelf piece only.
B. Lay the shelf down on the mating workpiece. Clamp the two
workpieces together and to the work surface in this position
(see Figure 32).
C. Set up the tool by selecting the proper biscuit size and setting
the adjustable fence angle at 0°.
D. Using the bottom registration surface, align the tool with the
biscuit location marks and make a vertical and a horizontal
plunge cut for each biscuit location as shown in Figure 33.
E. Glue, assemble and clamp the joint.
