Chainsaws
A chainsaw (or chain saw) is a portable handheld power saw that cuts with a set of teeth attached to a rotating chain driven along a guide bar. Modern chainsaws are typically gasoline or electric and are used in activities such as tree felling, limbing, bucking, pruning, cutting firebreaks in wildland fire suppression, harvesting of firewood, for use in chainsaw art and chainsaw mills, for cutting concrete, and cutting ice. Precursors to modern chainsaws were first used in surgery, with patents for wood chainsaws beginning in the late 19th century. A chainsaw comprises an engine, a drive mechanism, a guide bar, a cutting chain, a tensioning mechanism, and safety features. Various safety practices and working techniques are used with chainsaws. History In surgery A "flexible saw", consisting of a fine serrated link chain held between two wooden handles, was pioneered in the late 18th century (–1785) by two Scottish doctors, John Aitken and James Jeffray, for symphysiot ...

Chainsaw Mill
A chainsaw mill or PortaMill or Logosol sawmill is a type of sawmill incorporating a chainsaw, that is used by one or two operators to mill logs into lumber for use in furniture, construction and other uses. Although often used as a generic term, Alaskan Mill is a registered trademark of Granberg International. Description The mill attachment consists of a pair of clamping brackets connected to a rectangular frame which is attached to the bar of the chainsaw. The rails ride for the first cut on a guide system, plank or on a metal ladder which is screwed to the log (but not so tightly that the guide is pulled out of plane), and then on the previously cut surface of the log, and guide the chainsaw blade through the log at a consistent depth so that planks of a chosen thickness are cut. The distance between the rails and the bar determines this thickness and it can be adjusted by moving the rails along the depth posts at each end of the mill attachment. During use it is important ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

There are numerous types of hand saws and mechanical saws, and different types of blades and cuts. Description A saw is a tool consisting of a tough blade, wire, or chain with a hard toothed edge. It is used to cut through material, very often wood, though sometimes metal or stone. Terminology A number of terms are used to describe saws.

German People
Germans (, ) are the natives or inhabitants of Germany, or sometimes more broadly any people who are of German descent or native speakers of the German language.

During the 19th and much of the 20th century, discussions on German identity were dominated by concepts of a common language, culture, descent, and history.. "German identity developed through a long historical process that led, in the late 19th and early 20th centuries, to the definition of the German nation as both a community of descent (Volksgemeinschaft) and shared culture and experience. Today, the German language is the primary though not exclusive criterion of German identity." Today, the German language is widely seen as the primary, though not exclusive, criterion of German identity. Estimates on the total number of Germ ...

Joseph Buford Cox
Joseph Buford Cox (1905 – August 10, 2002), was an American inventor and businessman. He invented what is now known as the chipper type chain for chain saws. He based his design on the C-shaped jaws of the larva of the timberman beetle. Cox watched the destructive larvae of the timber beetle (Ergates spiculatus) for many hours. The beetle's cutting action was left and right, side to side, rather than scratching or burrowing straight ahead. Cox adapted this concept to a new chain saw of his own design put into production during the late 1940s. Joseph and his wife, Alice, founded "The Oregon Saw Chain Co." in 1947. Cox later started a small casting company called OMARK, now known as "Omark Industries". In time, Oregon Saw Chain became a subsidiary of Omark Industries which was in turn acquired in 1985 by Blount, Inc., of Montgomery, Alabama. Blount merged Mergers and acquisitions (M&A) are business transactions in which the ownership of a company, business organization, or one ...
