Butterfly Joint
A butterfly joint, also called a bow tie, dovetail key, Dutchman joint, or Nakashima joint, is a type of joint or inlay used to hold two or more pieces of wood together. These types of joints are mainly used for aesthetics, but they can also be used to reinforce cracks in pieces of wood, doors, picture frames, or drawers. A dovetail key resembles two dovetails connected at the narrow part. A negative of the hole is cut out of the board the butterfly will be 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. History Dutchman Joint The term Dutchman is used when a patch or inlay covers a miss-cut or an imperfect piece of wood. A Dutchman can also cover a knot in the wood. A Dutchman can be wood or metal. The name originated in San Francisco after the gold rush, when all types of European craftsmen came to California to earn a living. The term Dutchman is slang given to the woodwor ...

Dovetail Joint
A dovetail joint or simply dovetail is a joinery technique most commonly used in woodworking joinery (carpentry), including furniture, cabinets, log buildings, and traditional timber framing. Noted for its resistance to being pulled apart, also known as tensile strength, the dovetail joint is commonly used to join the sides of a drawer to the front. A series of pins cut to extend from the end of one board interlock with a series of 'tails' cut into the end of another board. The pins and tails have a trapezoidal shape. Once glued, a wooden dovetail joint requires no mechanical fasteners. History The dovetail 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, the tombs of Chinese emperors, and a stone pillar at the Vazhappally Maha Siva Temple in India. The dovetail design is an important method of distinguishing various periods of furni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dahshur Boats
The Dahshur boats are a group of ancient Egyptian funeral boats, originally numbering five or six, discovered near the funerary complex of the 12th Dynasty pharaoh Senusret III. Excavation The boats were found during excavations on the plain of Dahshur in 1894 and 1895 by French archaeologist Jacques de Morgan. His original excavation report recorded six boats; however, later reports by de Morgan stated there were only five. The boats fell into obscurity until two of the boats were studied in the mid-1980s. As of 2022, the locations of only four of the boats are known; The Carnegie boat and the Chicago boat are in the United States, located in the Carnegie Museum of Natural History in Pittsburgh, and the Field Museum of Natural History in Chicago, respectively.

Joinery
Joinery is a part of woodworking that involves joining pieces of wood, engineered lumber, or synthetic substitutes (such as laminate), to produce more complex items. Some woodworking joints employ mechanical fasteners, bindings, or adhesives, while others use only wood elements (such as dowels or plain mortise and tenon fittings). The characteristics of wooden joints—strength, flexibility, toughness, appearance, etc.—derive from the properties of the materials involved and the purpose of the joint. Therefore, different joinery techniques are used to meet differing requirements. For example, the joinery used to construct a house can be different from that used to make cabinetry or furniture, although some concepts overlap. In British English joinery is distinguished from carpentry, which is considered to be a form of structural timber work; in other locales joinery is considered a form of carpentry. History Many traditional wood joinery techniques use the distinctive m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
