T-JOINTS (Continued)

■

Plug your biscuit joiner into power supply and prepare to
cut slot.

■

Depress the switch trigger and let the motor build to its
maximum speed, then gradually push biscuit joiner forward
to extend the blade into the wood.

■

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.

■

Repeat this procedure for cutting all required slots in
vertical boards.

■

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.

■

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.

■

Clamp workpieces together until the glue sets up.

Upon completion of a T-joint cutting operation, reinstall
the fence on the front base by reversing "TO REMOVE
FENCE" procedure. Place height adjustment knob bolts in
key hole slots and align bolt heads with the slots on back of
front base. Slide fence up the front base to desired depth of
cut. Tighten height adjustment knobs securely.

MITER JOINTS

See Figures16-18.

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. Butt joints show the end grain in
wood.

HOW TO MAKE FLAT MITER JOINTS

■

Unplug your detail biscuit joiner.

WARNING:

Failure to unplug your detail biscuit joiner could result in
accidental starting causing possible serious personal injury.

■

Place the pieces of wood to be joined on a level
workbench as shown in figure 16.

■

Using a combination square, draw a line through the
center of each joint perpendicular to the mitered edges.

■

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.

■

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

■

Plug your biscuit joiner into power supply and prepare to
cut slot.
