Slowly plunge the cutter into the work-
piece.
Keep hands clear of the cutter.
Making Miter Box Joints
Generally miter box joints are fairly weak
because the joint is predominately endgrain
to endgrain. Tenons signifi cantly increase the
strength of the joint and make it easier to as-
semble and clamp the pieces.
Construction Tips
27
For thinner materials, keep the mortise
close to the inside corner. This minimizes
the chances for boring all the way through
the workpiece.
For thicker materials, stacked mortises can
be used as shown in the picture 28.
Setup and Machining
28
–
Tilt the fence to the appropriate angle.
–
Lower the fence to the desired height. Note
that the mortise should be close to the
inside corner to avoid penetrating through
the workpiece.
Tip:
Before milling the mortise, double check
your depth settings to ensure you don't cut
all the way through.
–
Grasp the joiner by the auxiliary handle for
best control. Plunge the joiner.
Making Frame Joints
Domino tenons can be used to quickly fabri-
cate reinforced frames of all types.
Butt Joint Frames
29
When making butt joint frames, such as cabi-
net faceframes, use pencil lines to lay out the
position of the tenons. Use the sight glass on
the joiner's fence [2.5] to position the joiner
over the pencil line.
For narrow frame stock, an optional narrow
frame fence is as accessory avaible.
Cope and Stick (Stile and Rail) Frames
30
Domino tenons can also be used to strengthen
cope and stick frame construction too. This is
typically found in raised panel door frames.
It is important to note that the two frame
pieces overlap, so the depth of the mortise
needs to be extended. The amount that each
mortise needs to be extended is one-half the
amount of overlap.
Example: A typical stile and rail router bit
set has a profi le width (overlap) of 3/8-inch
(about 10mm). For a 40mm long tenon, in-
stead of plunging 20mm deep, you should
increase this to 25mm for both workpieces.
