Shaving Horse
A shaving horse (shave horse, or shaving bench) is a combination of vice (tool), 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 Cooper (profession), coopering and bowyery. Operation The shavehorse is commonly used in the preparation of stock prior to turning in a lathe, to roughly form cylindrical billet (wood), 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 List of human positions#Riding positions, 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, ...

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. According to Collins Dictionary, the use of the term bodger in reference to green woodworking appeared between 1799 and 1827 and, to a much lesser extent, from 1877 to 1886 and from 1939 to present. 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. Bodgers also sold their waste product as kind ... [...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. Levers 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 deter ...

Switzerland
Switzerland, officially the Swiss Confederation, is a landlocked country located in west-central Europe. It is bordered by Italy to the south, France to the west, Germany to the north, and Austria and Liechtenstein to the east. Switzerland is geographically divided among the Swiss Plateau, the Swiss Alps, Alps and the Jura Mountains, Jura; the Alps occupy the greater part of the territory, whereas most of the country's Demographics of Switzerland, 9 million people are concentrated on the plateau, which hosts List of cities in Switzerland, its largest cities and economic centres, including Zurich, Geneva, and Lausanne. Switzerland is a federal republic composed of Cantons of Switzerland, 26 cantons, with federal authorities based in Bern. It has four main linguistic and cultural regions: German, French, Italian and Romansh language, Romansh. Although most Swiss are German-speaking, national identity is fairly cohesive, being rooted in a common historical background, shared ...

Germany
Germany, officially the Federal Republic of Germany, is a country in Central Europe. It lies between the Baltic Sea and the North Sea to the north and the Alps to the south. Its sixteen States of Germany, constituent states have a total population of over 84 million in an area of , making it the most populous member state of the European Union. It 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 Capital of Germany, nation's capital and List of cities in Germany by population, most populous city is Berlin and its main financial centre is Frankfurt; the largest urban area is the Ruhr. Settlement in the territory of modern Germany began in the Lower Paleolithic, with various tribes inhabiting it from the Neolithic onward, chiefly the Celts.

Black Forest
The Black Forest ( ) is a large forested mountain range in the States of Germany, 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 (Black Forest), 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 . 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 Baroque fortifications in the Black Forest, 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 ...

Lever
A lever is a simple machine consisting of a beam (structure), beam or rigid rod pivoted at a fixed hinge, or '':wikt:fulcrum, 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 Lever#Types of levers, three types. 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, which is mechanical advantage gained in the system, equal to the ratio of the output force to the input force. As such, the lever is a mechanical advantage device, trading off force against movement. Etymology The word "lever" entered English language, English around 1300 from . This sprang from the stem of the verb ''lever'', meaning "to raise". The verb, in turn, goes back to , itself from the adjective ''levis'', meaning "light" (as in "not heavy"). The word's primary origin is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire-setting
Fire-setting is a method of traditional mining used most commonly from prehistoric times up to the Middle Ages. Fires were set against a rock face to heat the stone, which was then doused with liquid, causing the stone to fracture by thermal shock. Rapid heating causes thermal shock by itself—without subsequent cooling—by producing different degrees of expansion in different parts of the rock (and in other materials). In practice, rapid cooling may or may not have been helpful to produce the desired effect. 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 opencast mines where the smoke and fumes could dissipate safely. The technique was very dangerous in underground workings without adequate ventilation. The method became largely redundant with the growth in use of explosives. Altho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Banc Etau
"Banq" and "banc" are alternative spellings used in company names to evade legal restrictions on the use of the word 'bank' while maintaining a similar pronunciation. This practice is common in the financial services industry, particularly in the United States. Origin and usage In the English language, banq and banc are alternative spellings 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). Leg ...
