    A variety of wood joints are used in furniture and cabinetry construction. They can vary in strength, depending on the joint and the design of the piece. Some traditional methods have been used in the past to create super strong wood joints. Today newer products and techniques have also developed. Following are some basic super-strong wood joints, both traditional and modern, and instructions on how to make them.

    The illustration shows a standard half-lap joint.


    A glued butt joint is the weakest, a half-lap joint is stronger and adding screws creates an even stronger joint. But traditionally, the strongest wood joint has been a mortise-and-tenon, including both a blind tenon and a “through” tenon. These joints may be used to create frames for frame-and-panel doors, for dust webs, or drawer supports, and even in basic furniture framing, such as legs and rails for tables and chairs. These joints may be created in several ways. Tenons can be cut using a table saw, band saw or by hand. A tenoning jig makes the chore easier and more precise. Mortises can be cut using a mortising machine, a mortising accessory in a drill press, or by drilling a series of holes with a drill press and cleaning up the cuts with a chisel. Adding a peg to the mortise and tenon joint creates an even stronger joint—one that is used to join timbers in timber-frame construction.

    Dovetail joint



    A stronger joint for these applications, and also a very traditional joint is the dovetail. These can be hand-cut, or cut with a dovetail jig and router with dovetail bit. Dovetails may also be “through,” which means you can see both ends of the stock, or stopped. The latter is often used on drawers where a more economical wood is used on the sides with a finer wood for the front.

    Dowel



    Another traditional joint is the dowel joint. This may be used to join boards edge-to-edge to create wider stock, or in framing as well. A doweling jig, drill and bits are used to bore precisely located holes to align the stock. Glue is used with the dowels to add strength.



    Edge-joined boards can also be joined using tongue-and-groove. This is often a method used to create backs for cupboards, not gluing the boards together, but holding them in a frame. This allows for the natural expansion and contraction of the wood.

    ITS FUNNY BECAUSE I OPENED THE THREAD EXPECTING TO READ ABOUT METHODS OF MAKING A JOINT, THE COMMON WAY OF PREPARING WEED BEFORE CONSUMPTION, BUT REALLY HE USED THE DOUBLE MEANING OF THE WORD 'JOINT' TO COMPLETELY THROW ME OFF COURSE AND IT TURNED OUT TO BE A THREAD ABOUT DIY! OMG! LOL!

    The 'Mortise and tenon' is more commonly referred to as a 'Tongue and groove' joint.
