WARNING:

Always wear safety goggles or safety glasses with side
shields when operating tools. Failure to do so could
result in objects being thrown into your eyes, resulting in
possible serious injury.

A variety of spline joints can be made using your plate joiner.
The number and size biscuits needed for each joint depends
on the thickness of the wood and the length of the joint. In
general, the small #0 biscuits should be used for miter cuts
in 3/4 in. materials. The larger biscuits should be used for
edge-to-edge joinery.

When joining 1-1/2 in. thick materials, stack two biscuits, one
above the other. For example, joining 2 in. x 4 in. dressed
lumber. 

See Figure 9. 

When joining even thicker materials,

use additional biscuits, stacked above each other.

When making edge-to-edge joints for tabletops, workbenches,
cutting boards, etc. the more biscuits you use, the stronger
the joint will be.

The following sections illustrate how to make various spline
joints using your plate joiner.

EDGE-TO-EDGE JOINTS

See Figures 7 and 8.

Edge-to-edge joinery is one of the most basic and easiest
joints to construct.  In general, two basic adjustments have
to be made for all biscuit joinery applications. One is the
depth of cut and the other is the location of the cut.

HOW TO MAKE EDGE-TO-EDGE JOINTS

Unplug your plate joiner.

Prepare the workpieces by laying them side by side on
a workbench in the order in which they will be assembled.

Using a square, determine the location of each biscuit
spline joint and mark the center of each joint by drawing
a line across each workpiece.

NOTE:

 Mark the edges 2 in. from the ends of workpieces.

The joint will be stronger if you use multiple biscuits
placed close together.

OPERATION

Loosen height adjustment knobs and set fence angle at
90

°

.

Slide the fence up or down until the indicator point is
aligned with the desired dimension on the scale.

REMEMBER:

  The scale indicates the height of the

fence from the center of the blade.

Tighten height adjustment knobs securely.

Select the correct depth of cut setting to match the
biscuit size you are planning to use. We suggest that you
make a test cut in a scrap piece of wood from the same
workpiece if possible.

Clamp workpiece securely so that it will not move during
the cut.

Plug your plate joiner into power supply and prepare to
make your first cut. Grasp and hold your plate joiner
securely with both hands by the front and rear handles
as shown on page 3.

Place the fence against the board and align the indicator
marks on the fence with the centerline mark(s) on the
board. 

See Figure 7.

Depress the switch trigger to turn the power on your
plate joiner, then push it 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 all desired biscuit slots.

Once all biscuit slots have been cut, place a biscuit in
each joint and dry assemble the workpieces. Make sure
each joint lines up and fits.
