__Box__ - {footnote sameas="1"}A corner joint with interlocking square fingers. Receives pressure from two directions. 

__{MOUSEOVER(label="Bridle" closeDelay="3")}{img type="fileId" fileId="328" thumb="box" width="400px" desc="Bridle Joint" alt="bridle joint"}

 {MOUSEOVER}__ - The bridle joint is often defined as the reverse of a mortise and tenon, and is chiefly used in the carpentry and joinery trades. The name probably originated from the fact that it bears some resemblance to the manner in which a bit slips into the horse's mouth and is fastened to the bridle.

__Butt__ - {FOOTNOTE()}Wikipedia contributors. "Woodworking joints." Wikipedia, The Free Encyclopedia. Wikipedia, The Free Encyclopedia, 11 Apr. 2020. Web. 15 May. 2020.{FOOTNOTE}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__ {FOOTNOTE()}Drawers, Author DC. “What Is A Dovetail Joint? Types of Dovetail Joinery.” DC Drawers Blog, 12 Dec. 2018, https://www.dcdrawers.com/blog/what-is-a-dovetail-joint-types/
{FOOTNOTE}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.

__{MOUSEOVER(label="Doweling" closeDelay="3")}{img fileId="333" thumb="box" width="400px" desc="Doweling a Mitered Frame" alt="doweling a mitered frame"}{MOUSEOVER}__ - Dowelling is the term generally given to the method of jointing timber and other materials by wooden or metal pegs, which are called dowels. For cabinet-making and similar work straight-grained beechwood dowels are mostly used; these may be bought by the gross, in lengths of about 36 ins., and of any desired diameter.

__Draw bore__ - The draw bore joint method of joinery is typically used in a ((Mortise and Tenon|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 {MOUSEOVER(label="trenail or trunnel pin" closeDelay="3")}{img type="fileId" fileId="428" thumb="box" width="400" responsive="y"} 
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.{MOUSEOVER}, the tenoned part will draw tightly into the mortise.

__{MOUSEOVER(label="Glued" closeDelay="3")}{img type="fileId" fileId="329" desc="Glued Joint" alt="glued joint"}{MOUSEOVER}__ - The glued joint is made by planing two pieces of timber so that when placed together they are in contact with each other at every point; they are then usually united with glue. Alternative names under which it is known are the butt joint, the rubbed joint, the slipped joint, whilst in certain localities it is known as the slaped (pronounced slayped) joint.

__{MOUSEOVER(label="Halved" closeDelay="3")}{img type="fileId" fileId="330" desc="Halved Joint" alt="halved joint" width="400"}{MOUSEOVER}__ - The halved joint is frequently known as half-lapping, and sometimes as checking and half-checking. In the majority of cases it is made by halving the two pieces, i.e., by cutting half the depth of the wood away. There are, however, exceptions to this rule, as in the case of "three-piece halving" (or, as it is sometimes called, "third lapping") and in the halving of timber with rebated or moulded edges. Halving is one of the simplest methods of connecting two pieces of timber, especially where it is desired to make frames and bracket supports for either inside or outside use.

__Lap__ - {footnote sameas="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.

__{MOUSEOVER(label="Saddle" closeDelay="3")}{img fileId="335" desc="Saddle Joint" alt="saddle joint" width="400"}{MOUSEOVER}__ - The "saddle joint" is used for connecting upright posts to heads or sills of framing, and undoubtedly takes its name from its similarity to the way in which the saddle fits the horse. It does not weaken the framing as does a mortise and tenon joint, and shrinkage has little effect upon the joint.

__{MOUSEOVER(label="Scarf" closeDelay="3")}{img fileId="334" desc="Plated Scarf Joint" alt="plated scarf joint" width="400"}{MOUSEOVER}__ - The method known as "scarfing" is used for the joining of timber in the direction of its length, enabling the workman to produce a joint with a smooth or flush appearance on all its faces. One of the simplest forms of scarfed joint is known as the half lap, in which a portion is cut out at the end of each beam or joist, equal in depth to half the full depth of the beam, and of equal length to the required scarf.

__{MOUSEOVER(label="Tongued and Grooved" closeDelay="3")}{img fileId="332" desc="Tongue and Grooved Flooring" alt="tongue and grooved flooring" width="400"}{MOUSEOVER}__ - The tongued and grooved joint is used in one form or another throughout the whole of the woodworking trades, covering, as it does, a great variety of work from the laying of flooring boards to the construction of dressers, bookcases and other cabinet work. As the name of the joint implies, one one board a groove is created, on the joining board a tongue is created, and the two are married or matched together.
