Intriguing Mortise and Tenon Foxed Dovetail Joint

This joint from Loyd Arve Nornes is an interesting one that has been rattling around my brain since I saw these videos.  It is a locking Mortise and Tenon Foxed Dovetail joint or some variation on those terms.  The slots in the piece of wood that makes up the tenon seem to be ripe for a tenon of a table apron or stretcher of a chair.


This second video adds some very interesting variations to the joint including a temporary locking method that might be a bit harder to pull of with wood, than his plastic model.


I want to play with making one, but haven’t come up with an appropriate project yet.
