Making Frame Joints
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 on the joiner’s fence to position the joiner over the pencil line.
For narrow frame stock, the optional Trim Stop can be used to securely hold the workpiece (shown below).
For larger frame stock, you may be able to use the stop pins for setting the mortise position.
Make sure to securely clamp the workpiece to the bench when mortising a mitered joint.

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.
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
Example: A typical stile and rail router bit set has a profile width (overlap) of
