Buzz Saw
A circular saw is a power-saw using a toothed or Abrasive saw, abrasive disk (mathematics), disc or blade to cut different materials using a rotary motion spinning around an Arbor (tool), 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 Miter saw#Power miter saw, 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 i ...

Rip-cut
The rift sawn rip cuts are perpendicular to the center of the log In woodworking, a rip-cut is a type of cut that severs or divides a piece of wood parallel to the grain. The other typical type of cut is a ''cross-cut'', a cut perpendicular to the grain. Unlike cross-cutting, which shears the wood fibers, a rip saw works more like a series of chisels, lifting off small splinters of wood. The nature of the wood grain requires the shape of the saw teeth to be different thus the need for both rip saws and crosscut saws; however some circular saw blades are ''combination blades'' and can make both types of cuts. A rip cut is the fundamental type of cut made at a sawmill.

Southampton
Southampton () is a port city in the ceremonial county of Hampshire in southern England. It is located approximately south-west of London and west of Portsmouth. The city forms part of the South Hampshire built-up area, which also covers Portsmouth and the towns of Havant, Waterlooville, Eastleigh, Fareham and Gosport. A major port, and close to the New Forest, it lies at the northernmost point of Southampton Water, at the confluence of the River Test and Itchen, with the River Hamble joining to the south. Southampton is classified as a Medium-Port City . Southampton was the departure point for the and home to 500 of the people who perished on board. The Spitfire was built in the city and Southampton has a strong association with the ''Mayflower'', being the departure point before the vessel was forced to return to Plymouth. In the past century, the city was one of Europe's main ports for ocean liners and more recently, Southampton is known as the home port of some of ...

Clapboard (architecture)
Clapboard (), also called bevel siding, lap siding, and weatherboard, with regional variation in the definition of these terms, is wooden siding of a building in the form of horizontal boards, often overlapping. ''Clapboard'' in modern American usage is a word for long, thin boards used to cover walls and (formerly) roofs of buildings. Historically, it has also been called ''clawboard'' and ''cloboard''. In the United Kingdom, Australia and New Zealand, the term ''weatherboard'' is always used. An older meaning of "clapboard" is small split pieces of oak imported from Germany for use as barrel staves, and the name is a partial translation (from , "to fit") of Middle Dutch and related to German . Types Riven Clapboards were originally riven radially producing triangular or "feather-edged" sections, attached thin side up and overlapped thick over thin to shed water.

Head Saw
A head saw, framesaw, gang saw or head rig is the saw that makes the initial cuts in a log at a sawmill, turning a log into cants, or planks of wood. History The original powered head saw was composed of long, narrow blades that used an up-and-down motion, a reciprocating saw. Each blade was set at a fixed width meaning each log was cut identically, regardless of flaws. This design was not energy efficient and around 1860 sawmills began to adopt the more efficient circular saw. In the 1870s, the limitation of log size due to the radius of the circular saw was improved with the introduction of the double circular saw- with one blade atop the other. In the 1880s, the band saw was introduced and was able to allow the head saw to handle logs of nearly unlimited size, ideal for the Californian redwoods. Modern use Today, head saws are mostly used for cutting logs in diameter depending upon the type of band mill the saws are mounted on. More optimized machines now cut the smalle ...

Lumber Edger
A lumber edger is a device with saws used to straighten and smooth rough lumber or bowed stock by making a cut along the sides of the boards. The result of this process is dimensional lumber. In a saw mill the edger is next in line from the head saw. The feed and press rollers on the edger are usually powered, passing the lumber through the machine. The length of feed and tables depends upon the lumber produced by the head saw. Edgers can be categorized as gang or shifting edgers. In gang edgers the saws remain stationary. In a shifting edger the saws can move left or right independently of one another. This allows setting the saws to best maximize the product that can be produced from a particular cant. See also *Sawmill *Resaw A resaw is a large band saw optimized for cutting timber along the grain to reduce larger sections into smaller sections or veneers. Resawing veneers requires a wide blade – commonly 2 to 3 inches (52–78 mm) – with a small kerf ... Re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
