Normally used for picture frames where they are nailed with panel pins. When used for other purposes they must be strengthened with glue blocks, angle braces or loose tongues. Miter Joints should always be glued. When nailing a miter Joint always start the nail with one part of the miter above the other. The nails will pull the miter into square. 3.

JOINERY Definition: Joinery is the method of Joining two or more pieces of wood together either by the use of adhesives or wood working with little or no fasteners.

In its simplest definition, Joinery is the method by which two or more pieces of wood are connected. Materials used in Joinery: Metal plates are often incorporated into the design where the timber alone would not be strong enough for a given load. Glue is highly effective for Joining timber when both surfaces of the Joint are edge grain. A properly glued Joint may be as strong as or stronger than a single piece of wood. However, glue is notably less effective on end-grain surfaces. Animal glue is soluble in water, producing Joints that can be disassembled using steam to soften he glue. Various mechanical fasteners may be used; the simplest being nails and screws. Glue and fasteners can be used together. Types of Joints used in Joinery Butt Joints – where two pieces of wood are connected by having the square end of one piece of wood placed against the side of the other in order to form a right angle. Nails, screws or dowels secure the Joint. Cross Lapped Joint – in this Joint, a rectangular section is taken out of each piece of wood and the wood fits together so that it is flush.

It is a type of interlocking Joint. Dado Joint – where two pieces of wood are connected by a groove in one piece of wood that is equal to the width of the second piece. The second piece of wood is inserted into the groove. Dovetail Joint – in this type of Join, the two lengths of wood are connected by cutting a piece out of one length of wood and flaring another piece in the second length which fits into the first length of wood. It can be helpful to think of it like a jigsaw puzzle, where the “out” piece fits into the “in” piece..

Miter Joint – this is where each end of the pieces of wood is cut on a 45 degree Engle and the pieces are Joined together to form a right angle. The Joint is secured using glue, nails or screws. Mortise and Tendon Joint – in this type of Joinery, one piece of wood has a mortise, or a recess cut into it and the other piece has a tendon or carved projection cut into it. The tendon is fitted into the mortise and they are then secured. Tongue and Groove Joint – in this type of Joint, two pieces of wood are Joined together by cutting a groove in one piece and an edge on the other.
