14. Repeat this procedure for cutting all required slots in
vertical boards.
15. Once all slots have been cut, place a biscuit in each joint
and dry assemble the workpieces. Make sure each joint
lines up and fits.
16. Finally, disassemble the workpieces and place a bead of
glue in each slot. Also, spread a bead of glue over the
entire surface of the joint. Reinsert the biscuits and
assemble the workpieces.
See Figure 11.
17. Clamp workpieces together until the glue sets up.
MITER JOINTS
See Figures16-19.
There are two types of miter joints that can be made using
biscuits: flat miters and edge miters. Flat miters are used
when making picture frames. Edge miters are used when
making boxes or things where you don't want to show the
end grain of the wood. NOTE: Butt joints show the end grain
in wood.
HOW TO MAKE FLAT MITER JOINTS
1. Unplug your plate joiner.
2. Place the pieces of wood to be joined on a level workbench
as shown in figure 16.
3. Using a combination square, draw a line through the
center of each joint perpendicular to the mitered edges.
4. Set fence angle at 90
°, set fence height at desired
dimension on the scale, select the correct depth of cut
setting for the biscuit size you plan to use, and clamp
workpiece securely.
5. Align indicator mark on fence with the centerline on the
workpiece.
6. Plug your plate joiner into power supply and prepare to
cut slot.
7. Depress the switch trigger to turn the power on your plate
joiner, then push it forward to extend the blade into the
wood.
8. When the base assembly bottoms out against the depth
of cut adjustment knob setting, pull back releasing
pressure on the spring. Blade will retract from biscuit slot.
9. Repeat this procedure for cutting mating slot and all
required miter joint slots.
10. Once all slots have been cut, place a biscuit in each joint
and dry assemble the workpieces. Make sure each joint
lines up and fits.
11. Finally, disassemble the workpieces and place a bead of
glue in each slot. Also, spread a bead of glue over the
entire surface of the joint. Reinsert the biscuits and
assemble the workpieces.
See Figure 16.
12. Clamp workpieces together until the glue sets up.
