Old World Joinery

Much of the modern, mass produced furniture makes extensive use of simple butt joints reinforced by mechanical fasteners.  In many cases, this is to make the piece of furniture capable of knocking down flat for transport, thus reducing shipping costs.  This is fine for furniture that you don't expect to keep for more than a few years.  It is inexpensive, so when it becomes too wobbly to use, just replace it.

An inset railBut for fine furniture that you expect to hand down through the generations, this will not do.  We build our furniture using the joinery techniques of the old masters.  We make extensive use of mortise & tenon joints for corners, we inset shelves and rails into stiles, notched lap joints are used in all our drawer grids.

Mortise & tenon joinery has all but disappeared from modern furniture construction.  This joint uses a long "tab" cut on the cross piece that fits snugly into a deep "pocket" cut into the upright piece.  This tab will go most of the way across the width of the upright, but not all the way.  This way the joint is completely hidden inside the wood.  Because this "tab" is smaller in section than the rest of the piece it's cut into, there are shoulders at the edge of the joint that draw up snugly against the upright.  When properly cut, properly glued and clamped to draw the joint up tight while the glue dries, this joint adds greatly to the rigidity of the piece being built.  The joints themselves hold the piece square and solid.  Dowel pins just can't do that.
