Wood Joinery is merely the way in which two pieces of timber are joined together, and this also proves strength at the crucial points on construction of Furniture alone with glues used.
We will cover Wood Joinery commonly used in manufacturing solid timber furniture.

Dovetail Joints
Dovetail joints have been used for centuries for building drawers, Chest, Boxes and other wooden projects. This method of joinery is exceptionally strong.
Mortise & Tenon
This type of joint is made up of two parts, the mortise (female) and the tenon (male).

The tenon on the end of one piece of timber is inserted into a cut out hole, cut into the joining timber. The tenon is cut to fit the mortise hole exactly. This joint may then be glued, pinned or wedged to lock into place.

Biscuit Joint
This is where a small biscuit is used to align two pieces of timber. For instance, a butt joint then this glued.
Butt Joint

This method of joinery is the most basic method of joinery, but accuracy is still required. A butt join is where one piece of timber is butted against another and glued. In some situations it may also be screwed or nailed.

Tongue and Groove
This is where a groove is cut all along the edge and a thin deep ridge (The tongue) on the adjoining piece of timber.
Finger Joint

This is created by cutting a set of complimentary rectangular cuts in two pieces of timber which are then glued together (e.g. to visualise this, simply interlock the fingers of your hands together).

Mitre Joint
Similar to the butt joint, but bother pieces have been cut on a 45 degree angle.
Grove Joint

This is where a slot is cut with the grain in which this enables a piece of timber to slide into this.
