Shaving Horse
A shaving horse (shave horse, or shaving bench) is a combination of vice and workbench, used for green woodworking. Typical usage of the shaving horse is to create a round profile along a square piece, such as for a chair leg or to prepare a workpiece for the pole lathe. They are used in crafts such as coopering and bowyery. Operation The shavehorse is commonly used in the preparation of stock prior to turning in a lathe, to roughly form cylindrical billets, the intermediate dressing phase between a crudely dressed raw split log and the final lathe work. As the name "horse" suggests, the worker sits astride the shaving horse. The clamp is operated by the operator pressing their feet onto a treadle bar below. A foot-actuated clamp holds the work piece securely against pulling forces, especially as when shaped with a drawknife or spokeshave. The shavehorse provides a rapid and sturdy clamp, which allows the operator to use their legs and upper body weight as additional "power" ...

Bodger
Bodging (full name Chair-Bodgering) is a traditional woodturning craft, using green (unseasoned) wood to make chair legs and other cylindrical parts of chairs. The work was done close to where a tree was felled. The itinerant craftsman who made the chair legs was known as a bodger or chair-bodger. History The term was once common around the furniture-making town of High Wycombe in Buckinghamshire, England. Traditionally, bodgers were highly skilled wood-turners, who worked in the beech woods of the Chiltern Hills. The term and trade also spread to Ireland and Scotland. Chairs were made and parts turned in all parts of the UK before the semi industrialised production of High Wycombe. As well recorded in Cotton the English Regional Chair. Although, originally the term was confined to High Wycombe, more recently since the revival of interest in pole lathe turning post 1980, many current chairmakers now call themselves bodgers. Bodgers also sold their waste product as kindling, o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mechanical Advantage
Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system. The device trades off input forces against movement to obtain a desired amplification in the output force. The model for this is the ''law of the lever.'' Machine components designed to manage forces and movement in this way are called mechanisms. An ideal mechanism transmits power without adding to or subtracting from it. This means the ideal machine does not include a power source, is frictionless, and is constructed from rigid bodies that do not deflect or wear. The performance of a real system relative to this ideal is expressed in terms of efficiency factors that take into account departures from the ideal. Lever The lever is a movable bar that pivots on a fulcrum attached to or positioned on or across a fixed point. The lever operates by applying forces at different distances from the fulcrum, or pivot. The location of the fulcrum determi ...

Germany
Germany,, officially the Federal Republic of Germany, is a country in Central Europe. It is the second most populous country in Europe after Russia, and the most populous member state of the European Union. Germany is situated between the Baltic and North seas to the north, and the Alps to the south; it covers an area of , with a population of almost 84 million within its 16 constituent states. Germany borders Denmark to the north, Poland and the Czech Republic to the east, Austria and Switzerland to the south, and France, Luxembourg, Belgium, and the Netherlands to the west. The nation's capital and most populous city is Berlin and its financial centre is Frankfurt; the largest urban area is the Ruhr. Various Germanic tribes have inhabited the northern parts of modern Germany since classical antiquity. A region named Germania was documented before AD 100. In 962, the Kingdom of Germany formed the bulk of the Holy Roman Empire. During the 16th ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Forest
The Black Forest (german: Schwarzwald ) is a large forested mountain range in the state of Baden-Württemberg in southwest Germany, bounded by the Rhine Valley to the west and south and close to the borders with France and Switzerland. It is the source of the Danube and Neckar rivers. Its highest peak is the Feldberg with an elevation of above sea level. Roughly oblong in shape, with a length of and breadth of up to , it has an area of about 6,009 km2 (2,320 sq mi). Historically, the area was known for forestry and the mining of ore deposits, but tourism has now become the primary industry, accounting for around 300,000 jobs. There are several ruined military fortifications dating back to the 17th century. History In ancient times, the Black Forest was known as , after the Celtic deity, Abnoba. In Roman times (Late antiquity), it was given the name ("Marcynian Forest", from the Germanic word ''marka'' = "border"). The Black Forest probably represented the bo ...

Lever
A lever is a simple machine consisting of a beam or rigid rod pivoted at a fixed hinge, or '' fulcrum''. A lever is a rigid body capable of rotating on a point on itself. On the basis of the locations of fulcrum, load and effort, the lever is divided into three types. Also, leverage is mechanical advantage gained in a system. It is one of the six simple machines identified by Renaissance scientists. A lever amplifies an input force to provide a greater output force, which is said to provide leverage. The ratio of the output force to the input force is the mechanical advantage of the lever. As such, the lever is a mechanical advantage device, trading off force against movement. Etymology The word "lever" entered English around 1300 from Old French, in which the word was ''levier''. This sprang from the stem of the verb ''lever'', meaning "to raise". The verb, in turn, goes back to the Latin ''levare'', itself from the adjective ''levis'', meaning "light" (as in "not heavy") ...

Fire-setting
Fire-setting is a method of traditional mining used most commonly from Prehistory, prehistoric times up to the Middle Ages. Fires were set against a rock face to heat the Rock (geology), stone, which was then doused with liquid, causing the stone to fracture by thermal shock. Some experiments have suggested that the water (or any other liquid) did not have a noticeable effect on the rock, but rather helped the miners' progress by quickly cooling down the area after the fire. This technique was best performed in Surface mining, opencast mines where the smoke and fumes could dissipate safely. The technique was very dangerous in Underground mining (hard rock), underground workings without adequate ventilation. The method became largely redundant with the growth in use of explosives. Although fire-setting was frequently used before modern history, modern times, it has been used sporadically since then. In some regions of the world, notably Africa and Eurasia, fire-setting continue ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Banc Etau
In the English language, banq and banc are coined words pronounced identically to the word "bank". Both terms have been adopted by financial services companies and others to satisfy legal restrictions on the usage of the word ''bank''. The compound bancorp (''banc''/''bank'' + '' corp ration') is often used in the names of bank holding companies. For example, a hypothetical chartered bank named Bank of Manhattan might form a holding company named "Manhattan Bancorp", and a sister insurance business named "Banc of Manhattan Insurance". One well-known past example was Bank of America's investment banking entity, named Banc of America Securities (now part of Bank of America Merrill Lynch). This practice originates from legal necessity: in the United States, the commerce departments of state governments generally prohibit or restrict the use of certain words in the names of corporations unless those corporations are legitimate chartered banks. For example, words prohibited by the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Circular Saw
A circular saw is a power- saw using a toothed or abrasive disc or blade to cut different materials using a rotary motion spinning around an arbor. A hole saw and ring saw also use a rotary motion but are different from a circular saw. ''Circular saws'' may also be loosely used for the blade itself. Circular saws were invented in the late 18th century and were in common use in sawmills in the United States by the middle of the 19th century. A circular saw is a tool for cutting many materials such as wood, masonry, plastic, or metal and may be hand-held or mounted to a machine. In woodworking the term "circular saw" refers specifically to the hand-held type and the table saw and chop saw are other common forms of circular saws. "Skilsaw" and "Skil saw" have become generic trademarks for conventional hand-held circular saws. Circular saw blades are specially designed for each particular material they are intended to cut and in cutting wood are specifically designed for ma ...
