"joint technique probably pre-dates written history. Some of the earliest known examples of the dovetail joint are in ancient Egyptian furniture entombed with mummies dating from First Dynasty, as well as the tombs of Chinese emperors. The dovetail design is an important method of distinguishing various periods of furniture. In Europe the dovetail joint is sometimes called a swallowtail joint, a culvertail joint, or a fantail joint. The dovetail joint is very strong because of the way the 'tails' and 'pins' are shaped. This makes it difficult to pull the joint apart and virtually impossible when glue is added. This"
"of the crack. Contemporary decorative dovetail keys are commonly seen in and associated with the work of George Nakashima. Butterfly joint A Dovetail key, Dutchman Joint, or Butterfly joint is a type of joint used either to hold two or more wooden boards together or to keep two halves of a board that have already started to split from splitting further. They may also be used to stabilize the core of a knothole, preventing it from dropping out over time. They are also commonly used as decorative inlays for non structural aesthetic purposes. A Dovetail Key resembles two dovetails connected"
"Butt joint A butt joint is a technique in which two pieces of material are joined by simply placing their ends together without any special shaping. The name 'butt joint' comes from the way the material is joined together. The butt joint is the simplest joint to make since it merely involves cutting the wood to the appropriate length and butting them together. It is also the weakest because unless some form of reinforcement is used (see below) it relies upon glue alone to hold it together. Because the orientation of the wood usually presents only one end to long"

"well known (and incompatible) cut profiles are those from sight manufacturers such as Novak, BoMar, LPA/TRT, Kimber or the 1911 mil standard (""GI""). Additionally many pistol manufacturers have their own proprietary dovetail cut profiles. Dovetail rail A dovetail rail or dovetail mount can refer to several types of brackets found on firearms primarily for mounting sights. Dovetail ""rails"" usually refer to any rail with a inverted trapezium (dovetail) cross-section (though the hexagonal-profiled Weaver rail and Picatinny rail are also derivative dovetail designs) running parallel to the bore for mounting a scope or diopter sight to a rifle. These are sometimes"
"which pieces of wood are joined together to make furniture or structures has a joinery tradition, wood joinery techniques have been especially well documented and is celebrated in the Indian, Chinese, European, and Japanese traditions. Because of the physical existence of Indian and Egyptian examples, we know that furniture from the first several dynasties show the use of complex joints, like the Dovetail, over 5,000 years ago. This tradition continued to other later Western styles. The 18th century writer Diderot included over 90 detailed illustrations of wood joints in his comprehensive encyclopedia. While Western techniques focused on concealment of joinery,"
"placed in and the butterfly is then fitted, keeping the joint together. The wood used for the butterfly is usually a contrasting wood, often walnut. Dovetail keys or Butterfly joints have been used both in decorative and structural joints since ancient times. They were prominently used in construction of the Cairo Dahshur Boats, a type of Khufu ship from the Egyptian middle kingdom. They were also historically used in repairing cracks in Dutch tabletops in the 18th century. This is where the term Dutchman joint originates. The dovetail key was installed across the crack to stabilize and inhibit further movement"
"Dovetail rail A dovetail rail or dovetail mount can refer to several types of brackets found on firearms primarily for mounting sights. Dovetail ""rails"" usually refer to any rail with a inverted trapezium (dovetail) cross-section (though the hexagonal-profiled Weaver rail and Picatinny rail are also derivative dovetail designs) running parallel to the bore for mounting a scope or diopter sight to a rifle. These are sometimes also called ""tip-off"" mounts, and allow the user to easily take on or off the sight. ""Dovetail mount"" can also refer to a dovetail track running perpendicular to the bore, see ""Other uses"" below."
"dovetail joint, mortise or flush joint. These joints are usually glued and can be reinforced with mechanical fasteners. Recently many manufacturers use bolt on fasteners. Bolt on neck joints were once associated only with less expensive instruments but now some top manufacturers and hand builders are using variations of this method. Some people believed that the Spanish style one piece neck/block and glued dovetail necks have better sustain, but testing has failed to confirm this. While most traditional Spanish style builders use the one piece neck/heel block, Fleta, a prominent Spanish builder, used a dovetail joint due to the influence"
"the vertical side casings where the elements join (creating a butt joint, as opposed to a miter joint). In an entablature in classical architecture, it is the lowest part, below the frieze and cornice. The word is derived from the Greek and Latin words ""arche"" and ""trabs"" combined together to mean ""main beam"". The architrave is different in the different orders. In the Tuscan, it only consists of a plain face, crowned with a fillet, and is half a module in height. In the Doric and composite, it has two faces, or fasciae; and three in the Ionic and Corinthian,"
"dovetail and multiple tongue and groove are used. Each piece has a slot (the ""groove"") cut all along one edge, and a thin, deep ridge (the ""tongue"") on the opposite edge. The tongue projects a little less than the depth of the groove. Two or more pieces thus fit together closely. The joint is not normally glued, as shrinkage would then pull the tongue off. In another assembly method, the pieces are end-matched. This method eliminates the need for mitre joints, face nailing, and the use of joints on or centres of conventional framing. For many uses, tongue and groove"
"Backsaw A backsaw is any hand saw which has a stiffening rib on the edge opposite the cutting edge, enabling better control and more precise cutting than with other types of saws. Backsaws are normally used in woodworking for precise work, such as cutting dovetails, mitres, or tenons in cabinetry and joinery. Because of the stiffening rib, backsaws are limited in the depth to which they can cut. Backsaws usually have relatively closely spaced teeth, often with little or no set. Backsaws include the tenon saw, the dovetail saw, and the (United Kingdom) sash saw. Tenon and dovetail saws usually"
"were generally made in three pieces called a butt, midsection, and tip. The butts were frequently made of maple, with bored bottom; this butt outlasted several tops. Midsections were generally made from ironwood because it was a thicker, strong wood. Tips were generally made from bamboo for its elasticity which could throw the bait further and more accurately. Handles and grips were generally of cork, wood, or wrapped cane. Many different types of glue held these sections together, most commonly Irish glue and bone glue. This was until hilton glue, or cement glue, was introduced because of its waterproof qualities."
"Mitre box A mitre box (US spelling, ""miter box"") is a wood working tool used to guide a hand saw to make precise mitre cuts in a board. The most common form of a mitre box is a 3-sided box which is open at the top and the ends. The box is made wide enough to accommodate the width of the boards to be cut. Slots are cut in the walls of the box at the precise angle at which the cut is to be made. These slots provide the guide for the saw to follow. Most commonly, the slots"
"Kicktail Kicktails are the upwards bent tips of a skateboard deck, today considered vital to a skateboard. The front kicktail is usually called the ""nose"" while the back kicktail is referred to as the ""tail"". Kicktails are nowadays key to maneuvering the board, especially in street skateboarding. As the name suggests, kicktails first emerged in the back end of a skateboard only. As street skating progressed, they were made to the front ends of skateboards in an attempt to increase the height of ollies, succeeding beyond all expectations and pushing the sport even further. Kicktails are also found on specific"

It is made from three pieces of rectangular-section 13 mm-thick steel (legs) held together with a shackle, allowing connection to a lifting hook. The middle leg is square throughout its length. The outer legs are thinner at the top, flaring towards the bottom. Held together, the three legs form a dovetail shape. The lewis hole seating is undercut (similar to a chain-linked lewis hole) to match its profile. The first outer leg is inserted"

The ends of the arm and body are the toes. The names of ship’s knees are based on their position: Knees can be blind pegged with foxtail wedges on both ends or bolted in place. Due to tradition, ease of workability, strength and durability characteristics, some species of wood are particularly prized for making knees. Tamarack (also known as hackmatack) stumps are among the preferred softwood species for grown knees, while"
"mouldings that is commonly used is the mitre joint but this technique relies upon knowing the precise angle between the walls for neat results. Coping is only ever used for internal corners. External corners are always mitred. The main reason that scribed joints are used is that timber shrinks in width far more than it does in length. By using a scribed joint rather than an internal mitre joint the effect of shrinkage is minimised. Also it is possible to arrange the scribed joints pointing away from the most common viewpoint (usually the doorway of a room) and so present"
"groove is cut along the middle of each inner face of the lower timber in each panel. Vertical slender timbers, known as staves, are then inserted and these hold the whole panel within the timber frame. The staves are positioned into the holes and then sprung into the grooves. They must be placed with sufficient gaps to weave the flexible horizontal wattles. In some places or cultures, the technique of wattle and daub were used with different materials thus has different names, including pug and pine, mud and stud (stud and mud), hourdis, rab (rad) and dab, pierrotage/bousillage (bouzillage) and"

""Dovetail mount"" can also refer to a dovetail track running perpendicular to the bore, often used for smaller front sights posts and rear sights blades found on handguns and some rifles. This mounting method is meant as a semi-permanent friction fit mounting solution where a slot is milled, for instance in the slide of a pistol, and a sight with a corresponding dovetail is punched or drifted into that slot. Rear sights are offered in many dovetail cut profiles which are non-compatible, and some"
"Miter joint A miter joint (mitre in British English, sometimes shortened to miter) is a joint made by beveling each of two parts to be joined, usually at a 45° angle, to form a corner, usually a 90° angle. For woodworking, a disadvantage of a miter joint is its weakness, but it can be strengthened with a spline. There are two common variations of a splined miter joint, one where the spline is long and runs the length of the mating surfaces and another where the spline is perpendicular to the joined edges. Common applications include picture frames, pipes, and"

"Brattice A brattice is a partition used in mining. It is built between columns of a sub-surface mine to direct air for ventilation. Where the mine is sunk at the base of a single shaft, the shaft is divided into two parts by a wooden or metal brattice. Air is delivered down one side of the shaft and exhausted upwards through the other. Depending on the type of mine and how the operation is run, brattices can be permanent (concrete or wood) or temporary (cloth). Temporary installations are also called curtains. Early collieries sometimes only had one pit which was"

They are shaped like a piece of pipe (but with thicker walls), with their cutting edges on the inside surface. They are used on turret lathes and screw machines as an alternative to turning with a box tool, or on milling machines or drill presses to finish a cylindrical boss (such as a trunnion). A dovetail cutter is an end mill whose form leaves behind a dovetail slot, such as often forms the ways of a machine tool. A shell mill is any of various milling"
"Treenail A treenail, also trenail, trennel, or trunnel, is a wooden peg, pin, or dowel used to fasten pieces of wood together, especially in timber frames, covered bridges, wooden shipbuilding and boat building. It is driven into a hole bored through two (or more) pieces of structural wood (mortise and tenon). The use of wood as a tenon can be traced back over 7,000 years, as archaeologist have found traces of wood nails in the excavation of early Germanic sites. Trenails are notoriously economical and readily available, making them a common early building material. Honey Locust is a favorite wood"
"fairly recent innovation in butt joint construction. It is used primarily in carcase and frame construction. The ""biscuit"" is an oval shaped piece of specially dried and compressed wood, usually beech, which is installed in matching mortises in both members of the joint in a similar fashion to a loose or floating tenon. Biscuit joints are common in both frame and carcase construction. They are particularly convenient for panel glue ups as they facilitate alignment of panel members. To create the mortise for the biscuit, a biscuit joiner is usually required. There are other methods of cutting the slot, such"

The technique of skew-nailing is applied so that nails are not parallel to each other and so resist the pulling apart of the joint. This form of butt joint is rarely used in furniture making. Use for: The dowel reinforced butt joint or simply ""dowel joint"" has been a very common method of reinforcing butt joints in furniture for years. They are common in both frame and carcase construction. Dowel joints are popular in chairs, cabinets, panels and tabletops."

On the Scawbrig (United Kingdom) or Meroth (Germany) bitless bridles, the reins connect to a strap that passes through a ring on one side of a noseband, under the chin, and attaches to the opposite ring. Thus, pressure is applied only to the bridge of the nose and the chin but not to the branches of the lower jaw, cheek or poll. In a mechanical hackamore, also known as a hackamore bit, brockamore, and English hackamore, the reins attach to shanks (like bit shanks on a curb bit) that are attached between a"
"Brettstapel Brettstapel, also known as dowellam, is a massive timber construction system, fabricated exclusively from softwood timber posts connected with hardwood timber dowels. It is a relatively simple method of construction that exploits low grade timber, not normally suitable for use in construction, to form load bearing solid timber wall, floor and roof panels. Brettstapel works by using hardwood dowels with a moisture content lower than that of softwood posts. Over time the dowels expand to achieve moisture equilibrium thus 'locking' the posts together and creating a structural load-bearing system. It is one of a few construction methods that can"

In solid timber, docking of members for a butt joint is usually a crosscut, so a crosscut saw is best for this job. When working with sheetgoods, there is no distinction between crosscut and rip cut. The joint members can be docked by any of the following methods: To overcome their inherent weakness, butt joints are usually reinforced by one of the following methods: This is the most common form of the butt"
"Bridle joint A bridle joint is a woodworking joint, similar to a mortise and tenon, in that a tenon is cut on the end of one member and a mortise is cut into the other to accept it. The distinguishing feature is that the tenon and the mortise are cut to the full width of the tenon member. The corner bridle joint (also known as a slot mortise and tenon) joins two members at their respective ends, forming a corner. This form of the joint is commonly used to house a rail in uprights, such as legs. It provides good"
