Box - 1 A corner joint with interlocking square fingers. Receives pressure from two directions.Bridle
Butt - 1 The end of a piece of wood is butted against another piece of wood. This is the simplest and weakest joint. Of those, there is the a) T-butt, b) end-to-end butt, c) Miter butt and d) edge-to-edge butt.
Dovetail 2 See various types of Dovetail joinery below:
- Through - A Through joint is where the end grain is visible from both boards. Through dovetail joints are most commonly used on box construction and carcass (framework of the piece). This joint is also called a plain dovetail by many in the woodworking community. In the past the ends showing through would have been masked by a veneer. Today they are a sign of exceptional quality and are left showing with pride.
- Half-blind - A half-blind dovetail joint also known as the single-lap dovetail joint is exactly opposite of a through joint because the end grain is not visible on the boards. Sockets house the tails at the end of the boards so the dovetail ends are invisible. Half-blind dovetail joints are commonly used for attaching drawer fronts.
- Secret mitered - A secret mitred joint is also know as a full-blind mitred dovetail and full-blind dovetail joint. Secret mitered joints are used in box work and cabinet construction and offers the best strength out of all of the dovetail joints. These joints are used for box work or fine cabinet construction where strength is needed without a joint you can see.
- Secret double-lapped - The secret double-lapped dovetail joint is kind of the like the mitred joint but has a visible section of end grain on a single edge of the joint. similar to the secret mitred dovetail, but presents a very thin section of end grain on one edge of the joint. Secret double-lapped joints are used for box construction and carcass construction to hid the dovetails.
- Sliding - The sliding dovetail joint is created by joining 2 wood boards at 90 degree angles, where the they intersect different than other types of dovetail joints. They intersect by sliding the tail of one board into the middle socket of the other. Sliding dovetail joints are commonly referred to French Dovetail joints. Sliding joints are commonly used to joint cabinet sides to shelves, sides to cabinet bottoms, shelves to horizontal partitions, table frames to adjacent sections, sides to drawer fronts, cabinet sides to front rails, body and neck in guitars and violins.
Draw bore - The draw bore joint method of joinery is typically used in a mortise and tenon joint. Some times in order to add additional strength to a mortise and tenon joint the crafts-person will bore through the joint and add a pegs or dowels to secure the tenon to the mortise, going a step further, one would also bore a hole(s) in the mortised part, then bore a hole(s) in the tenoned part that are offset slightly, then insert and ram home a trenail or trunnel pin Oak trenails that will be used to pin a wooden structure together. The one in the front has been used and pulled, showing the way forces have permanently deformed the wood., the tenoned part will draw tightly into the mortise.
Lap - 1 The end of a piece of wood is laid over and connected to another piece of wood. Due to a large surface area of long-grain to long-grain wood and glue surface coverage, this is a very strong joint.
Mitering - The term mitering is generally used to denote the type of joint used at the corner of a picture frame; or where two pieces of wood are bevelled away so as to fit each other, as the skirting or plinth mould. In these cases the timber is cut so that the joint is at 45 degrees to the face, and the two pieces, when placed together, form an angle of 90 degrees (a right angle).
Mortise and Tenon - A mortise (or mortice) and tenon joint is a type of joint that connects two pieces of wood or other material. Woodworkers around the world have used it for thousands of years to join pieces of wood, mainly when the adjoining pieces connect at an angle of 90°. In its basic form, it is both simple and strong.
