HOW TO MAKE EDGE MITER JOINTS

1.

Unplug your plate joiner.

2. Place the pieces of wood to be joined on a level workbench

as shown in figure 17.

3. Mark centerline of the joint on each board.

4. When making edge miter joints with workpieces that

have different thicknesses, clamp securely to a
workbench with the long sides up. This will assure that
the outside surfaces will match. 

See Figure 18.

5. Loosen height adjusting knobs and set fence angle at

135

°

.

6. Slide the fence up or down until fence height is at desired

setting.

7. Tighten height adjustment knobs securely.

8. Place your plate joiner on workpiece with the adjustable

fence resting on the long side of workpiece as shown in
figure 18. The base or vertical fence should be against
the mitered edge of the workpiece.

9. Recheck fence height setting to make sure it will not cut

through the workpiece.

10. Align indicator mark on fence with the centerline on the

workpiece. Make sure the base or vertical fence is
pressed flat against the mitered edge of the workpiece.

11. Plug your plate joiner into power supply and prepare to

cut slot.

12. Depress the switch trigger to turn the power on your plate

joiner, then push it forward to extend the blade into the
wood.

13. 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.

14. Repeat this procedure for cutting mating slot and all

required miter joint slots.

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 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 workpieces. 

See Figure 17.

17. Clamp workpieces together until the glue sets up.

If the workpieces are the same thickness,  clamp securely to
a workbench with the short sides up. 

See Figure 19. 

Set

fence angle at 45

°

. Place your plate joiner on the workpiece

with the adjustable fence resting on the short side of the
workpiece and the base or vertical fence against the mitered
edge of the workpiece. Follow steps 9-17 above to cut
required slots.  

REMEMBER: 

Before cutting slots, make

sure blade will not cut through the workpiece and that both
the vertical and horizontal fences are pressed flat against the
mitered edge and face of the workpiece.
