Woodwork
Woodworking is the skill of making items from wood, and includes cabinetry, furniture making, wood carving, joinery, carpentry, and woodturning. History Along with stone, clay and animal parts, wood was one of the first materials worked by early humans. Microwear analysis of the Mousterian stone tools used by the Neanderthals show that many were used to work wood. The development of civilization was closely tied to the development of increasingly greater degrees of skill in working these materials. Among the earlliest finds of woodworking are shaped sticks displaying notches from Kalambo Falls in southen Africa, dating to around 476,000 years ago.

Woodworking Joints
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 mate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carpentry
Carpentry is a skilled trade and a craft in which the primary work performed is the cutting, shaping and installation of building materials during the construction of buildings, Shipbuilding, ships, timber bridges, concrete formwork, etc. Carpenters traditionally worked with natural wood and did rougher work such as framing, but today many other materials are also used and sometimes the finer trades of cabinetmaking and furniture building are considered carpentry. In the United States, 98.5% of carpenters are male, and it was the fourth most male-dominated occupation in the country in 1999. In 2006 in the United States, there were about 1.5 million carpentry positions. Carpenters are usually the first tradesmen on a job and the last to leave. Carpenters normally framed post-and-beam buildings until the end of the 19th century; now this old-fashioned carpentry is called timber framing. Carpenters learn this trade by being employed through an apprenticeship training—normally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Woodturning
Woodturning is the craft of using a wood lathe with hand-held tools to cut a shape that is symmetrical around the axis of rotation. Like the potter's wheel, the wood lathe is a mechanism that can generate a variety of forms. The operator is known as a ''turner'', and the skills needed to use the tools were traditionally known as ''turnery''. In pre-industrial England, these skills were sufficiently difficult to be known as "the mysteries of the turners' guild." The skills to use the tools by hand, without a fixed point of contact with the wood, distinguish woodturning and the wood lathe from the machinist's lathe, or metal-working lathe. Items made on the lathe include tool handles, candlesticks, egg cups, knobs, lamps, rolling pins, cylindrical boxes, Christmas ornaments, bodkins, knitting needles, needle cases, thimbles, pens, chessmen, spinning tops; legs, spindles, and pegs for furniture; balusters and newel posts for architecture; baseball bats, hollow forms such a ...

Cabinetry
A cabinet is a case or cupboard with shelves or drawers for storing or displaying items. Some cabinets are stand alone while others are built in to a wall or are attached to it like a medicine cabinet. Cabinets are typically made of wood (solid or with veneers or artificial surfaces), coated steel (common for medicine cabinets), or synthetic materials. Commercial grade cabinets usually have a melamine-particleboard substrate and are covered in a high-pressure decorative laminate commonly referred to as Wilsonart or Formica. Cabinets sometimes have one or more doors on the front, which are mounted with door hardware, and occasionally a lock. Cabinets may have one or more doors, drawers, or shelves. Short cabinets often have a finished surface on top that can be used for display, or as a working surface, such as the countertops found in kitchens. A cabinet intended to be used in a bedroom and with several drawers typically placed one above another in one or more columns inte ...

Furniture
Furniture refers to objects intended to support various human activities such as seating (e.g., Stool (seat), stools, chairs, and sofas), eating (table (furniture), tables), storing items, working, and sleeping (e.g., beds and hammocks). Furniture is also used to hold objects at a convenient height for work (as horizontal surfaces above the ground, such as tables and desks), or to store things (e.g., cupboards, Shelf (storage), shelves, and drawers). Furniture can be a product of design and can be considered a form of decorative art. In addition to furniture's functional role, it can serve a symbolic or Religion, religious purpose. It can be made from a vast multitude of materials, including metal, plastic, and wood. Furniture can be made using a variety of woodworking joints which often reflects the local culture. People have been using natural objects, such as tree stumps, rocks and moss, as furniture since the beginning of human civilization and continues today in some househol ...

Kalambo Falls
Archaeological sites of Eastern Africa Archaeological sites of Southern Africa The Kalambo Falls on the Kalambo River is a single-drop waterfall on the border of Zambia and Rukwa Region, Tanzania at the southeast end of Lake Tanganyika. The falls are some of the tallest uninterrupted falls in Africa (after South Africa's Tugela Falls, Ethiopia's Jin Bahir Falls and others). Downstream of the falls is the Kalambo Gorge, which has a width of about 1 km and a depth of up to 300 m, running for about 5 km before opening out into the Lake Tanganyika rift valley. The Kalambo waterfall is the tallest waterfall in both Tanzania and Zambia. The expedition which mapped the falls and the area around it was in 1928 and led by Enid Gordon-Gallien. Initially it was assumed that the height of falls exceeded 300 m, but measurements in the 1920s gave a more modest result, above 200 m. Later measurements, in 1956, gave a result of 221 m. After this several more ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linear Pottery Culture
The Linear Pottery culture (LBK) is a major archaeological horizon of the European Neolithic period, flourishing . Derived from the German ''Linearbandkeramik'', it is also known as the Linear Band Ware, Linear Ware, Linear Ceramics or Incised Ware culture, falling within the Danubian I culture of V. Gordon Childe. Most cultural evidence has been found on the middle Danube, the upper and middle Elbe, and the upper and middle Rhine. It represents a major event in the initial spread of agriculture in Europe. The pottery consists of simple cups, bowls, vases, jugs without handles and, in a later phase, with pierced lugs, bases, and necks.Hibben, page 121. Important sites include Vráble and Nitra in Slovakia; Bylany in the Czech Republic; Langweiler and Zwenkau (Eythra) in Germany; Brunn am Gebirge in Austria; Elsloo, Sittard, Köln-Lindenthal, Aldenhoven, Flomborn, and Rixheim on the Rhine; Lautereck and Hienheim on the upper Danube; and Rössen and Sond ...

Wood
Wood is a structural tissue/material found as xylem in the stems and roots of trees and other woody plants. It is an organic materiala natural composite of cellulosic fibers that are strong in tension and embedded in a matrix of lignin that resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or more broadly to include the same type of tissue elsewhere, such as in the roots of trees or shrubs. In a living tree, it performs a mechanical-support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients among the leaves, other growing tissues, and the roots. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, woodchips, or fibers. Wood has been used for thousands of years for fuel, as a construction material, for making tools and weapons, furniture and paper. More recently it emerged as a feedstock for the production ...

Wood Carving
Wood carving (or woodcarving) is a form of woodworking by means of a cutting tool (knife) in one hand or a chisel by two hands or with one hand on a chisel and one hand on a mallet, resulting in a wooden figure or figurine, or in the sculpture, sculptural ornamentation of a wooden object. The phrase may also refer to the finished product, from individual sculptures to hand-worked mouldings composing part of a tracery. The making of sculpture in wood has been History of wood carving, extremely widely practised, but does not survive undamaged as well as the other main materials like Stone sculpture, stone and bronze, as it is vulnerable to decay, insect damage, and fire. Therefore, it forms an important hidden element in the art history of many cultures. Outdoor wood sculptures do not last long in most parts of the world, so it is still unknown how the totem pole tradition developed. Many of the most important sculptures of China and Japan, in particular, are in wood, and so are th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lehringen Spear
The straight-tusked elephant (''Palaeoloxodon antiquus'') is an extinct species of elephant that inhabited Europe and Western Asia during the Middle and Late Pleistocene. One of the largest known elephant species, mature fully grown bulls on average had a shoulder height of and a weight of . Straight-tusked elephants likely lived very similarly to modern elephants, with herds of adult females and juveniles and solitary adult males. The species was primarily associated with temperate and Mediterranean woodland and forest habitats, flourishing during interglacial periods, when its range would extend across Europe as far north as Great Britain and Denmark and eastwards into Russia, while persisting in southern Europe during glacial periods, when northern Europe was occupied by steppe mammoths and later woolly mammoths. Skeletons found in association with stone tools and in one case, a wooden spear, suggest they were scavenged and hunted by early humans, including ''Homo heidelber ...

Stitching Awl
A stitching awl is a tool with which holes can be punctured in a variety of materials, or existing holes can be enlarged. It is also used for sewing heavy materials, such as leather or canvas. It is a thin, tapered metal shaft, coming to a sharp point, either straight or slightly bent. These shafts are often in the form of interchangeable needles. They usually have an eye piercing at the pointed end to aid in drawing Yarn, thread through holes for the purpose of manual lockstitch sewing, in which case it is also called a sewing awl. Stitching awls are frequently used by shoe repairers and other leatherworkers. Sewing awls are used to make lock stitches. The needle, with the thread in the eye is pushed through the material. The thread is then pulled through the eye to extend it. As the needle is pushed through the material, the extra thread from the first stitch is then threaded through the loops of successive stitches creating a lock stitch. The action is likened to that of a "m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flint
Flint, occasionally flintstone, is a sedimentary cryptocrystalline form of the mineral quartz, categorized as the variety of chert that occurs in chalk or marly limestone. Historically, flint was widely used to make stone tools and start fires. Flint occurs chiefly as nodules and masses in sedimentary rocks, such as chalks and limestones.''The Flints from Portsdown Hill'' Inside the nodule, flint is usually dark grey or black, green, white, or brown in colour, and has a glassy or waxy appearance. A thin, oxidised layer on the outside of the nodules is usually different in colour, typically white and rough in texture. The nodules can often be found along s and [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
