Wood joinery

Wood joinery is the process of connecting two or more wooden pieces, which can be categorized into two types: joints made solely from wood, and those reinforced with mechanical fasteners and adhesives.

Types of wood joints

Joint	Image	Description
Butt joint		Simplest and weakest joint. Created by butting an endpiece of a piece of wood to an another piece of wood. Requires adhesives or fasteners.
Miter joint		A butt joint in which the pieces were beveled. Stronger than a butt joint but still quite weak.
Lap joint		The end of a piece of wood is laid over and connected to another piece of wood.
Bridle joint		Also known as a tongue and fork joint or open mortise and tenon. One piece has a necked joint and the other one has a slit cut for it.
Mortise and tenon		A tenon (stub) fitted inside a mortise (hole cut for it). Quite popular and strong. Improvement over the bridle joint.
Box joint		A corner joint with interlocking square fingers.
Dovetail joint		A box join in which the fingers are diagonally cut.
Tongue and groove		Each piece has a groove cut along one edge and a ridge fitting the groove on the other.
Dowel joint		A butt joint which is reinforced by dowel pins.
Birdsmouth joint		Used in roof construction. An angled square cut is connected to the other piece of wood.
