Chainsaw
A chainsaw (or chain saw) is a portable gasoline-, electric-, or battery-powered saw that cuts with a set of teeth attached to a rotating chain driven along a guide bar. It is used in activities such as tree felling, limbing, Log bucking, bucking, pruning, cutting firebreaks in wildland fire suppression, and harvesting of Wood fuel#Firewood, firewood. Chainsaws with specially designed bar-and-chain combinations have been developed as tools for use in Chainsaw carving, chainsaw art and chainsaw mills. Specialized chainsaws are used for cutting concrete during construction developments. Chainsaws are sometimes used for cutting ice; for example, ice sculpture and winter swimming in Finland. History In surgery The origin of chain saws in surgery is debated. A "flexible saw", consisting of a fine serrated link chain held between two wooden handles, was pioneered in the late 18th century (c. 1783–1785) by two Scottish doctors, John Aitken and James Jeffray, for symphysiotomy and ...

Chainsaw Carving
The art of chainsaw carving is a fast-growing form of art that combines the modern technology of the chainsaw with the ancient art of woodcarving. The beginning of the art form The oldest chainsaw artist records go back to the 1950s, which include artists Ray Murphy and Ken Kaiser. In 1952 Ray Murphy used his father's chainsaw to carve his name into a piece of wood. In 1961 Ken Kaiser created 50 carvings for the Trees of Mystery. Many new artists began to experiment with chainsaw carving, including Brenda Hubbard, Judy McVay, Don Colp, Cherie Currie (former Runaways lead singer), Susan Miller, Mike McVay, and Lois Hollingsworth. At this time chainsaw carvers started loading up their carvings in the back of their trucks, functioning as traveling galleries. In the 1980s the art form really began to grow with Art Moe getting much exposure for the craft at the Lumberjack World Championships held in Hayward, Wisconsin. This event was broadcast nationally. The addition of carvi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Andreas Stihl
Andreas Stihl (10 November 1896 in Zürich, Switzerland – 14 January 1973 in Rohrbronn, Baden-Württemberg, Germany) was a Swiss-born German engineer and important inventor in the area of chainsaws, and the founder of Andreas Stihl AG & Company KG. He is often hailed as the "Father of the chainsaw". Early life Stihl went to the Volksschule in Zürich, before moving to relatives in Germany. He attended the Realschule in Singen (Baden-Württemberg) and the Gymnasium in Düsseldorf-Oberkassel. From 1915 until his dismissal by injuries in 1917, Stihl fought in the First World War in the German Army. From 1917 until 1920, he studied mechanical engineering in Eisenach. Invention of the chainsaw In 1923, together with his friend Carl Hohl, he founded an engineering firm in Stuttgart, which was dissolved in 1926. Stihl founded a new company, for steam boiler prefiring systems, in the same year. He also patented the "Cutoff Chainsaw for Electric Power" in 1926, which wei ...

Chainsaw Mill
A chainsaw mill or PortaMill or Alaskan mill or Alaskan sawmill 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. Description The mill attachment consists of a pair of guide rails which are attached to the bar of the chainsaw. The rails ride for the first cut on a 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 a post at each end of the mill attachment. During use it is important that the rails extend out past the ends of the log so the cut has support the entire time. Small mills use a single chainsaw and ...

Limbing
Limbing or delimbing is the process of removing branches from a standing or fallen tree trunk. In logging, limbing follows felling. Limbing plays a role in fire prevention by removing branches from live trees that can otherwise serve as part of a fuel ladder allowing a fire to climb from the ground into the tree canopy. A California fire prevention guide recommends to "Remove all tree branches at least 6 feet .8 metersfrom the ground" and "Allow extra vertical space between shrubs and trees." Ready For Wildfire, In , limbing can be synon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dolmar
Makita Engineering Germany GmbH (Dolmar) is one of the oldest manufacturers of portable gasoline chainsaws and is headquartered in Hamburg, Germany. The company founder, Emil Lerp, developed in 1927 the "type A" saw, which weighed and required two men to operate. It was tested on Mount Dolmar in the Thüringer Thuringian sausage, or ''Thüringer Bratwurst'' in German language, German is a unique sausage from the German state of Thuringia which has Protected geographical indications in the European Union, protected geographical indication status un ... forest and the company took its name from the test site.

Pruning
Pruning is a horticultural, arboricultural, and silvicultural practice involving the selective removal of certain parts of a plant, such as branches, buds, or roots. The practice entails the ''targeted'' removal of diseased, damaged, dead, non-productive, structurally unsound, or otherwise unwanted plant material from crop and landscape plants. Some try to remember the categories as "the 4 D's": the last general category being "deranged". In general, the smaller the branch that is cut, the easier it is for a woody plant to compartmentalize the wound and thus limit the potential for pathogen intrusion and decay. It is therefore preferable to make any necessary formative structural pruning cuts to young plants, rather than removing large, poorly placed branches from mature plants. In nature, meteorological conditions such as wind, ice and snow, and salinity can cause plants to self-prune. This natural shedding is called abscission. Specialized pruning practices may be ...

Chain
A chain is a wikt:series#Noun, serial assembly of connected pieces, called links, typically made of metal, with an overall character similar to that of a rope in that it is flexible and curved in compression (physics), compression but line (geometry), linear, rigid, and load-bearing in tension (physics), tension. A chain may consist of two or more links. Chains can be classified by their design, which can be dictated by their use: * Those designed for lifting, such as when used with a Hoist (device), hoist; for pulling; or for securing, such as with a bicycle lock, have links that are torus shaped, which make the chain flexible in two dimensions (the fixed third dimension being a chain's length). Small chains serving as jewellery are a mostly decorative analogue of such types. * Those designed for transferring power in machines have links designed to mesh with the teeth of the sprockets of the machine, and are flexible in only one dimension. They are known as roller chains, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Emil Lerp
Emil Lerp (1 January 1886 – 1 January 1966) was a German businessman and inventor of the first mass produced transportable gasoline chainsaw. Career Lerp was born in Goldbach, Saxe-Coburg and Gotha in 1886. In 1927, he invented the transportable gasoline chainsaw. Lerp tested his invention on a hill called Dolmar, and named his company after the testing site. On 15 June 1928, Lerp received a patent in Germany for his invention.Baedeker-Reiseführer: ''Thüringen.'' Third edition.

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 in 1999 with Lehman Brothers Merchant Banking Partners and became known as Blount International, Inc. Today the company is kn ...
