Introduction
Examine Figure 1 and your plate joiner for a few minutes to become familiar with the various
features and the names used to describe them. The following sections will discuss the vari-
ous controls and you will need to know where they are.
Overview
You have purchased a precision woodworking tool. The function of the plate joiner is to enable
you to make extremely strong and accurate joints in wood and wood by products.
The tool works by a plunging action to precisely cut crescent shaped slots for the placement
of flat wooden dowels or “biscuits” like those shown in Figure 2.
The various adjustments on the patented base/fence assembly will enable you to make virtu-
ally any biscuit joint imaginable. The tool may be further enhanced by some simple jigs and
fixtures that can be easily made. Some of the more common biscuit joinery applications are
shown in Figure 3 and are discussed in detail in the applications section of this manual.
Switch
Your plate joiner has a trigger switch located on the underside, as shown in Figure 1. To turn
the tool on, depress the trigger. To turn the tool off, release the trigger. To lock the tool on for
continuous operation, there is a lock on button located at the rear of the tool just above the
cord. When cutting always hold the tool with one hand on the switch handle and one hand on
the auxiliary handle. To lock the tool on, depress and hold the trigger as you depress the lock
button. Hold the lock button in as you gently release the trigger. The tool will continue to run.
To turn the tool off from a locked on condition, depress and release the trigger once.
Blade Replacement
In time your saw blade will wear out and need replacement. To remove the blade, follow the
steps below.
1. Turn off and unplug the plate joiner.
2. Remove the 4 torx head screws from the bottom of the shoe, using the T20 torx screw-
driver provided.
3. Rotate the shoe out of the way.
4. Use the spanner wrench provided to loosen (counterclockwise) the blade nut. Depress the
spindle lock pin on the top of the gear case to hold the spindle while you unscrew the nut.
5. Remove the blade and have it sharpened or replace it with a new one.
6. Reinstall the blade by reversing the steps above. Be sure blade teeth point counterclock-
wise as shown in Figure 4.
7. IMPORTANT: Always check the fine depth adjustment when sharpening or replacing the
blade. Adjust if necessary. (See "Controls" section).
The Controls
The heart of your plate joiner is the base/fence assembly. All of the controls that let you make a
variety of precision cuts are located on this assembly. Take a few minutes to become familiar
with the various controls.
ALWAYS TURN OFF AND UNPLUG PLATE JOINER BEFORE MAKING ANYADJUSTMENTS.
1. ADJUSTABLE FENCE
The adjustable fence provides a sturdy, precise reference surface to determine the point at
which the slots for the biscuits will be cut. Its adjustable height feature allows you to position
biscuit slots as close as 3/16" (4.76mm) and as distant as 1-3/8" (35mm) measured from the
workpiece surface to the centerline of the blade (see Figure 6). The adjustable angle feature
allows a full range of settings from 0° to 90 as well as a reverse 45° bevel which allows
outside registration on miter joints. (See Applications section under Miter Joints, Figure 26.)
The height adjustment is accomplished by first loosening the lock knob on the right side of
the fence and then rotating the knurled adjustment knob until the desired height is reached
(see Figure 5).
Tightening the lock knob will then automatically align the fence parallel to the blade and lock
it in position. The vertical scale and pointer located directly under the lock knob can be used
to assist in setting this height. The scale readings indicate distance from the blade centerline
to the fence surface when the fence is set at 90° (see Figure 6). The fence angle can be set
simply by loosening the lock knob on the left side of the tool, aligning the protractor scale
with the pointer and tightening the lock knob.
2. PLUNGE DEPTH ADJUSTMENT
The depth of cut can be set to match the dimensions of the particular size biscuit you will be
using. The numbers on the depth adjustment knob (0,10,20,M) coincide with the three sizes
of biscuits shown in Figure 2. The letter M stands for the maximum depth capacity of the tool
which is 20mm (25/32"). This depth is obtainable only with a new blade and by backing out
the fine adjustment screw (see next section).
NOTE: The M setting has been provided for future use and will not be necessary for most
biscuiting operations. To select a depth, align the appropriate number with the red mark
scribed in the tool’s housing, as shown in Figure 7. Rotate the depth adjustment knob to
the desired position and it will “click” into place.
3. FINE DEPTH ADJUSTMENT
You may encounter situations where you want to leave a little looseness in your joint so
that you can move it slightly before the glue sets up. For these instances a fine depth
adjustment has been provided. To adjust, you must first raise the adjustable fence to its
uppermost position. Then insert the T20 torx wrench provided into the opening as shown
in Figure 8. Turn the depth adjustment screw clockwise for less depth and counterclock-
wise for increased depth. Each full turn causes a change in depth of 1mm (0.04"). Always
check the depth adjustment by first making test cuts in scrap wood.
4. ANTI-SLIPPAGE PINS
Plate Joiners tend to slide to the right with respect to the workpiece when making a cut.
This tendency is increased with a dull blade or when plunging very rapidly. Anti-slippage
pins have been provided to reduce this tendency and are located on the front registration
surface on either side of the blade opening slot. When making some joints, you may wish
to retract the anti-slippage pins so as not to scratch your workpiece in a visible area. For
this purpose, simply rotate the anti-slippage pins approximately 1/6 of a turn and they will
retract back behind the front registration surface. A flat blade screwdriver can be used to
rotate the pins as shown in Figure 9.
5. BOTTOM REGISTRATION SURFACE
For certain applications, you will want to use the bottom surface of the plate joiner for
alignment. When using the bottom registration surface, the adjustable fence should be set
to 0° and the height setting is unimportant. This surface is used primarily when making ‘T’
joints (see applications section). The distance between the centerline of the blade and the
bottom registration surface is fixed at 3/8" (9.5mm) which allows centering on 3/4" (19mm)
thick stock. The 3 red marks on the bottom registration surface indicate the centerline (or
the deepest point) of the biscuit cut and the approximate width of a #20 biscuit so that
you’ll know where the edge of the blade is and can prevent breakthrough. To avoid break-
ing through the workpiece, align the shoe so that neither outside mark extends beyond
the end of the workpiece. If either side does, there is a good chance that the blade will
break through the surface and ruin your work.
6. DUST EXTRACTION
There are three options provided for collecting dust from your plate joiner as described
below.
A. Adjustable Direction Elbow (See Figure 10)
This attachment inserts into the dust exhaust port on the right side at the rear of the
base assembly and clicks into place. To remove, pull out firmly. The directional elbow
rotates easily to aim the dust in the most convenient direction suitable for the particu-
lar application.
B. Dust Adaptor (See Figure 11)
This attachment, when inserted as described above, allows the use of several common
sizes of vacuum hose to be attached for direct vacuum pick-up of the dust.
C. Dust Bag (See Figure 12)
The dust bag provided fits snugly over the dust adaptor described above. To empty the
bag, open the zipper underneath and dump dust out.
NOTE: When the bag becomes full, the dust will back-up into the adaptor and the
exhaust port on the right rear of the tool. To clean out, turn off and unplug the tool and
remove packed dust. The bag will hold the dust generated from approximately 70 to
100 #20 biscuit cuts before filling up.
General Operation
Plate joiners are primarily used for making cabinetry and furniture, joining millwork or other
similar applications where a strong, accurate joint is required in wood or wood by-products.
There are literally hundreds of variations of joints that can be made with your Plate Joiner. We
will limit our discussion to six basic joints that can be used to build on and adapt to your own
applications. The following are some basic set-up steps that will apply to all biscuit joints.
1. BISCUIT SIZE SELECTION
As mentioned earlier, the three biscuit sizes are #0, #10 and #20. It is a good rule of thumb
to use the largest biscuit size that will physically fit in the application. Unless you are
joining narrow face or picture frames or using 1/2" or thinner stock, you will find the #20
