Workbench
A workbench is a sturdy table at which manual work is done. They range from simple flat surfaces to very complex designs that may be considered tools in themselves. Workbenches vary in size from tiny jewellers benches to the huge benches used by staircase makers. Almost all workbenches are rectangular in shape, often using the surface, corners and edges as flat/square and dimension standards. Design is as varied as the type of work for which the benches are used but most share these attributes: * A comfortable height for working with provisions for seated or standing work * A way to fix the workpiece to the surface so that it may be worked with both hands * Provisions for mounting, storing and accessing tools Workbenches are made from many different materials including metal, wood, stone, and composites depending on the needs of the work. Types Workbench types may be divided according to the particular work they are designed to accommodate: ;Multi-purpose/portable: These be ...

Workbench (woodworking)
A workbench is a specialized workbench table used by woodworking, woodworkers. Features include a flat, solid work surface and one or more means of holding the material being worked on. Styles There are many styles of woodworking bench. Styles of workbenches include Nicholson (sometimes referred to as the English workbench), Moravian, Scandinavian (or European) and Roubo (or French). Historically, the style choice was dependent on the woodworker's training or dictated by the region. Currently, with woodworking being so popular as a hobby, workbench choice is often dependent on the type of work being done or the preferred method of working. All styles aim to keep the workpieces immobile while work is being performed. This is accomplished by making them heavy (Scandinavian and Roubo) or in their geometry (Nicholson and Moravian). Holding the work Vise A woodworking vise holds work in its jaws, or compressed against a bench dog or Holdfast (tool), holdfast. Holes to recei ...

Workbench (AmigaOS)
Workbench is the desktop environment and graphical spatial file manager, file manager of AmigaOS developed by Commodore International for their Amiga line of computers. Workbench provides the user with a graphical interface to work with file systems and launch applications. It uses a workbench metaphor (in place of the more common desktop metaphor) for representing file system organisation. "Workbench" was also the name originally given to the entire Amiga operating system up until version 3.1. From release 3.5 the operating system was renamed "AmigaOS" and subsequently "Workbench" refers to the graphical front end only. Overview The Amiga Workbench uses the metaphor of a workbench (i.e. a workbench for manual labor), rather than the now-standard desktop metaphor, for representing file system organization. The desktop itself is called ''Workbench'' and uses the following representations: ''drawers'' (instead of folders) for directories, ''tools'' for executable programs, ''p ...

Black & Decker Workmate
The Black & Decker Workmate is a general purpose portable workbench and general carpentry tool manufactured under the brand Black & Decker. It is a folding table for portability, but when unfolded stands about tall. The table top consists of two wooden jaws, one of which is fixed and the other moveable on threaded rods operated by handles. It can be used as a bench vice to hold wood, metal and other parts, either clamped between the jaws or, using supplied bench dogs, clamped on the table top. The jaws are wide enough to hold most bench top tools, such as a drill press, planer, miter saw, etc. When invented, the designer Ron Hickman had difficulty convincing anyone to market the Workmate, and sold them himself at trade shows. He had his first breakthrough in 1968, after convincing a DIY magazine to let him exhibit at the Ideal Home Exhibition in London, which enabled him to sell 1,800 units that year. After seeing some success in 1971, Black & Decker decided to work with Hickm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vise (tool)
A vise or vice (British English) is a mechanical apparatus used to secure an object to allow work to be performed on it. Vises have two parallel jaws, one fixed and the other movable, threaded in and out by a screw and lever. The jaws are often flat but may have grooves, adapt to the shape of the workpiece or be custom made. A vise grip is not a vise but a pair of lever-actuated locking pliers. Etymology The etymology of ''vise'' can be tracked via Middle English ''vys'' Anglo-French ''vyz'' from Latin ''vitis'' "vine". The tight grip of the mechanical device was likened to that of the twines of the plant. Types Face A face vise is the standard woodworking vise, always securely attached to a workbench flush with its work surface. Its jaws are made of wood or metal, the latter usually faced with wood, called cheeks, to avoid marring the work. The movable jaw may include a retractable dog to hold work against a bench dog. A "quick-release" woodworker's vise employs a spl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Welding Table
A welding table is a type of workbench used for holding Workpiece, workpieces during welding. They are made of fireproof and electrically conductive materials, and often have good possibilities for clamping workpieces down, providing increased stability, precision and security. In addition to a welding machine and personal protective equipment, they are often used together with accessories such as measuring tools, magnets and angles. Some welders build their own welding tables. Fire safety They are often made of steel, and some welding tables have a Electroplating, zinc plating to prevent slag from sticking to the table. The table can withstand Melting point, high temperatures and splashes of hot slag, unlike a Wood, wooden table which can catch fire more easily. This reduces the risk of Combustibility and flammability, risk of fire. Grounding They are often connected to Ground (electricity), ground to prevent Voltage, voltage leaks during work and to protect the welder from ...

Workpiece
A workpiece is a piece, often made of a single material, that is being processed into another desired shape (such as building blocks). The workpiece is usually a piece of relatively rigid material such as wood, metal, plastic, or stone. After a processing step, the workpiece may be moved on to further steps of processing. For example, a part can made out of bar stock and later become part of a semi-finished product. The workpiece is often attached to the tool being used via a jig or fixture, like for example to a milling machine via an angle plate, or to a lathe via a lathe faceplate. A vise is another example of a simple type of fixture used to fix workpieces. A workpiece may be subjected to various cutting operations, like truing, making fillets, chamfers, countersinking, counterboring, etc. It may also receive various surface treatments and finishes. The term "workpiece" has established itself within crafts and the manufacturing industry, and connects the work or tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Handloading
Handloading, or reloading, is the practice of making firearm cartridges by manually assembling the individual components ( metallic/ polymer case, primer, propellant and projectile), rather than purchasing mass-assembled, factory-loaded commercial ammunition. (It should not be confused with the reloading of a firearm ''with'' cartridges, such as by swapping detachable magazines, or using a stripper clip or speedloader to quickly insert new cartridges into a magazine.) The term ''handloading'' is the more general term, and refers generically to the manual assembly of ammunition cartridges. ''Reloading'' refers more specifically to handloading using previously fired cases and shotshells. The terms are often used interchangeably however, as the techniques are largely the same, whether the handloader is using new or recycled components. The differences lie in the initial preparation of cases or shells — new components are generally ready to load straight out of the box, w ...

Electrician
An electrician is a tradesman, tradesperson specializing in electrical wiring of buildings, transmission lines, stationary machines, and related equipment. Electricians may be employed in the installation of new electrical components or the maintenance and repair of existing electrical infrastructure. Electricians may also specialize in wiring ships, airplanes, and other mobile platforms, as well as data and cable lines. Terminology ''Electricians'' were originally people who demonstrated or studied the principles of electricity, often electrostatic generators of one form or another. In the United States, electricians are divided into two primary categories: Lineman (technician), lineperson, who work on electric utility company electricity distribution, distribution systems at higher voltages, and wiremen, who work with the lower voltages utilized inside buildings. Wiremen are generally trained in one of five primary specialties: commercial, residential, light industrial ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steel
Steel is an alloy of iron and carbon that demonstrates improved mechanical properties compared to the pure form of iron. Due to steel's high Young's modulus, elastic modulus, Yield (engineering), yield strength, Fracture, fracture strength and low raw material cost, steel is one of the most commonly manufactured materials in the world. Steel is used in structures (as concrete Rebar, reinforcing rods), in Bridge, bridges, infrastructure, Tool, tools, Ship, ships, Train, trains, Car, cars, Bicycle, bicycles, Machine, machines, Home appliance, electrical appliances, furniture, and Weapon, weapons. Iron is always the main element in steel, but other elements are used to produce various grades of steel demonstrating altered material, mechanical, and microstructural properties. Stainless steels, for example, typically contain 18% chromium and exhibit improved corrosion and Redox, oxidation resistance versus its carbon steel counterpart. Under atmospheric pressures, steels generally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
