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 woods 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 origin of the name is from San Francisco after the gold rush. All types of European craftsmen came to California to earn a living. The term Dutchman is slang given to the woo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 (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 furniture. The et ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jacques De Morgan
Jean-Jacques de Morgan (3 June 1857, Huisseau-sur-Cosson, Loir-et-Cher – 14 June 1924) was a French people, French mining engineer, geologist, and archaeologist. He was the director of antiquities in Khedivate of Egypt, Egypt during the 19th century, and excavated in Memphis, Egypt, Memphis and Dashur, providing many drawings of many Egyptians, Egyptian pyramids. He also worked at Stonehenge, and Persepolis, and many other sites. He also went to Russian Armenia, as manager of a copper mine at Akhtala. "The Caucasus is of special interest in the study of the origins of metals; it is the easternmost point from which prehistoric remains are known; older than Europe and Greece, it still retains the traces of those civilizations that were the cradle of our own." In 1887-89 he unearthed 576 graves around Alaverdi, Armenia, Alaverdi and Akhatala, near the Tiflis-Alexandropol railway line. Background His father Eugène, also called "Baron" de Morgan, was an engineer in mineral f ... [...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. The Red boat and the White boat were on display in the Cairo Museum, but were later relocated to the Sharm El-Sheikh Museum. Characteristics The boats are each about long and are constructed of cedar wood. They ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dahshur
DahshurAlso transliterated ''Dahshour'' (in English often called ''Dashur'' ar, دهشور ' , ''Dahchur'') is a royal necropolis located in the desert on the west bank of the Nile approximately south of Cairo. It is known chiefly for several pyramids, two of which are among the oldest, largest and best preserved in Egypt, built from 2613 to 2589 BC. Pyramids The Dahshur pyramids were an extremely important learning experience for the Egyptians. It provided them with the knowledge and know-how to transition from step-sided pyramids to smooth-sided pyramids. Ultimately their breadth of experience would allow them to build the Great Pyramid of Giza; the last of the Seven Wonders of the Ancient World still standing to this date. The first of the Dahshur pyramids was the Bent Pyramid (2613–2589 BC), built under the rule of King Sneferu. The Bent Pyramid was the first attempt at building a smooth sided pyramid, but proved to be an unsuccessful build due to the miscalculati ...

Bandsaw
A bandsaw (also written band saw) is a power saw with a long, sharp blade consisting of a continuous band of toothed metal stretched between two or more wheels to cut material. They are used principally in woodworking, metalworking, and lumbering, but may cut a variety of materials. Advantages include uniform cutting action as a result of an evenly distributed tooth load, and the ability to cut irregular or curved shapes like a jigsaw.. The minimum radius of a curve is determined by the width of the band and its kerf. Most bandsaws have two wheels rotating in the same plane, one of which is powered, although some may have three or four to distribute the load. The blade itself can come in a variety of sizes and tooth pitches (teeth per inch, or TPI), which enables the machine to be highly versatile and able to cut a wide variety of materials including wood, metal and plastic. Almost all bandsaws today are powered by an electric motor. Line shaft versions were once common but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. While a form of carpentry elsewhere, in British English usage it is distinguished from it, which is considered to be a form of structural timber work. History Many traditional wood joinery techniques use the distinctive material properties of wood, often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
