16 Domino DF 500 Tenon Joiner
Making Frame Joints
Domino tenons can be used to quickly fabricate reinforced
frames of all types.
Butt Joint Frames
When making butt joint frames, such as cabinet
faceframes, use pencil lines to lay out the position of the
tenons. Use the sight gauge (see page 22 for more
information) on the joiner’s fence to position the joiner
over the pencil line.
For narrow frame stock, the optional narrow frame fence
(also called the trim stop) can be used to securely hold the
workpiece (shown below).
Cope and Stick (Stile and Rail) Frames
Domino tenons can also be used to strengthen cope and
stick frame construction too (bottom right picture). 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
profile width (overlap) of 3/8-inch (about 10mm). For a
40mm long tenon, instead of plunging 20mm deep, you
should increase this to 25mm for both workpieces.
Mitered Frames
When making mitered frames, position the tenon closer to
the inside corner. This reduces the likelihood of cutting the
mortise all the way through the workpiece.
Make sure to securely clamp the workpiece to the bench
when mortising a mitered joint.
