Bar Clamp
An F-clamp, also known as a bar clamp or speed clamp, is a type of clamp. The name comes from its "F" shape. The F-clamp is similar to a C-clamp in use, but has a wider opening capacity (throat). This tool is used in woodworking while more permanent attachment is being made with screws or glue, or in metalworking to hold pieces together for welding or bolting. An F-clamp consists of two horizontal bars joined together by a vertical bar. There is a large screw on the lower bar to allow for the clamp to be tightened. F-clamps are adjustable which allows for them to be used on larger scale objects without the need for a large screw. An F-clamp is also a simple mechanical device used for lifting engine or transmission parts. The clamp has an adjusting screw to tighten onto the part and a lifting ring to attach a hoist cable. F-clamps in the industry terminology have the jaws mounted on a flat bar, while a pipe clamp, which has the same construction, is mounted on a pipe, normally ...

Transmission (mechanics)
Propulsion transmission is the mode of transmitting and controlling propulsion power of a machine. The term ''transmission'' properly refers to the whole drivetrain, including clutch, gearbox, prop shaft (for rear-wheel drive vehicles), differential, and final drive shafts. In the United States the term is sometimes used in casual speech to refer more specifically to the gearbox alone, and detailed usage differs. The transmission reduces the higher engine speed to the slower wheel speed, increasing torque in the process. Transmissions are also used on pedal bicycles, fixed machines, and where different rotational speeds and torques are adapted. Often, a transmission has multiple gear ratios (or simply "gears") with the ability to switch between them as the speed varies. This switching may be done manually (by the operator) or automatically (by a control unit). Directional (forward and reverse) control may also be provided. Single-ratio transmissions also exist, which simply cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Irwin Industrial Tools
Irwin Industrial Tools is an American manufacturer and distributor of hand tools and power tool accessories. It is owned by Stanley Black & Decker. It is best known for producing Vise-Grip locking pliers. Additionally, it produces clamps, drill bits, taps and dies, screw extractors, bolt extractors, saw blades, pipe wrenches, screwdrivers, snips, and other construction tools. History Irwin was founded in 1885 in Martinsville, Ohio as the Irwin Auger Bit Company by Charles Irwin, a pharmacist. Irwin had bought the rights to a solid-center auger bit from a local blacksmith. In 1924, another blacksmith, Danish immigrant William Petersen of DeWitt, Nebraska, invented the first locking pliers and named them Vise-Grips. In 1934, Petersen formed the Petersen Manufacturing Company to produce them. In 1957, Petersen added an easy-release trigger to the design, creating the modern locking pliers design. In 1985, American Tool Companies bought out Petersen Manufacturing. In 1993, Ameri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Desk
A desk or bureau is a piece of furniture with a flat table (furniture), table-style work surface used in a school, office, home or the like for academic, professional or domestic activities such as reading (activity), reading, writing, or using equipment such as a computer. Desks often have one or more Drawer (furniture), drawers, compartments, or pigeonholes to store items such as office supplies and papers. Desks are usually made of wood or metal, although materials such as glass are sometimes seen. Some desks have the form of a table (furniture), table, although usually only one side of a desk is suitable to sit at (there are some exceptions, such as a partners desk), unlike most usual tables. Some desks do not have the form of a table, for instance, an armoire desk is a desk built within a large wardrobe-like cabinet (furniture), cabinet, and a portable desk is light enough to be placed on a person's lap. Since many people lean on a desk while using it, a desk must be sturdy. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maple
''Acer'' () is a genus of trees and shrubs commonly known as maples. The genus is placed in the family Sapindaceae.Stevens, P. F. (2001 onwards). Angiosperm Phylogeny Website. Version 9, June 2008 nd more or less continuously updated since http://www.mobot.org/MOBOT/research/APweb/. There are approximately 132 species, most of which are native to Asia, with a number also appearing in Europe, northern Africa, and North America. Only one species, ''Acer laurinum'', extends to the Southern Hemisphere.Gibbs, D. & Chen, Y. (2009The Red List of Maples Botanic Gardens Conservation International (BGCI) The type species of the genus is the sycamore maple, '' Acer pseudoplatanus'', the most common maple species in Europe.van Gelderen, C. J. & van Gelderen, D. M. (1999). ''Maples for Gardens: A Color Encyclopedia'' Maples usually have easily recognizable palmate leaves ('' Acer negundo'' is an exception) and distinctive winged fruits.

Glue
Adhesive, also known as glue, cement, mucilage, or paste, is any non-metallic substance applied to one or both surfaces of two separate items that binds them together and resists their separation. The use of adhesives offers certain advantages over other binding techniques such as sewing, mechanical fastenings, or welding. These include the ability to bind different materials together, the more efficient distribution of stress across a joint, the cost-effectiveness of an easily mechanized process, and greater flexibility in design. Disadvantages of adhesive use include decreased stability at high temperatures, relative weakness in bonding large objects with a small bonding surface area, and greater difficulty in separating objects during testing. Adhesives are typically organized by the method of adhesion followed by ''reactive'' or ''non-reactive'', a term which refers to whether the adhesive chemically reacts in order to harden. Alternatively, they can be organized eithe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pipe Clamp
A pipe clamp is a type of clamp often employed in woodworking, piping or cabinet shops. When referring to woodwork or cabinet shops, pipe clamps are usually composed of commercially manufactured clamp heads or "jaws" and a length of common threaded pipe. The capacity of the clamp is determined by the length of the pipe used. When referring to piping, pipe clamps are used to connect the pipe to the pipe hanger assembly. Description In woodwork, a pipe clamp uses clamp heads produced commercially by numerous manufacturers. They are available in various diameter sizes, commonly ½”or ¾”, suited to the same diameter piping. The pipe is usually threaded on both ends. One head is fixed on the pipe by spinning it onto standard pipe threads. This head includes the screw mechanism for tightening the clamp. The other, movable, head slides onto the other end of the pipe. This head has a mechanism, often a series of movable “clutches” which allow it to slide along the pipe w ...

Bolted Joint
A bolted joint is one of the most common elements in construction and machine design. It consists of a male threaded fastener (e. g., a bolt) that captures and joins other parts, secured with a matching female screw thread. There are two main types of bolted joint designs: tension joints and shear joints. Joint types In a tension joint, the bolt and clamped components of the joint are designed to transfer an applied tension load through the joint by way of the clamped components by the design of a proper balance of joint and bolt stiffness. The joint should be designed such that the clamp load is never overcome by the external tension forces acting to separate the joint. If the external tension forces overcome the clamp load (bolt preload) the clamped joint components will separate, allowing relative motion of the components. The second type of bolted joint transfers the applied load in shear of the bolt shank and relies on the shear strength of the bolt. Tension loads on such ...

Clamp (tool)
A clamp is a fastening device used to hold or secure objects tightly together to prevent movement or separation through the application of inward pressure. In the United Kingdom the term cramp is often used instead when the tool is for temporary use for positioning components during construction and woodworking; thus a G cramp or a sash clamp but a wheel clamp or a surgical clamp. There are many types of clamps available for many different purposes. Some are temporary, as used to position components while fixing them together, others are intended to be permanent. In the field of animal husbandry, using a clamp to attach an animal to a stationary object is known as "rounded clamping." A physical clamp of this type is also used to refer to an obscure investment banking term, "fund clamps." Anything that performs the action of clamping may be called a clamp, so this gives rise to a wide variety of terms across many fields. Types Temporary These clamps (or cramps) are used to po ...

Welding
Welding is a fabrication (metal), fabrication process that joins materials, usually metals or thermoplastics, by using high heat to melt the parts together and allowing them to cool, causing Fusion welding, fusion. Welding is distinct from lower temperature techniques such as brazing and soldering, which do not melting, melt the base metal (parent metal). In addition to melting the base metal, a filler material is typically added to the joint to form a pool of molten material (the weld pool) that cools to form a joint that, based on weld configuration (butt, full penetration, fillet, etc.), can be stronger than the base material. Pressure may also be used in conjunction with heat or by itself to produce a weld. Welding also requires a form of shield to protect the filler metals or melted metals from being contaminated or Oxidation, oxidized. Many different energy sources can be used for welding, including a gas flame (chemical), an electric arc (electrical), a laser, an electron ...

Metalworking
Metalworking is the process of shaping and reshaping metals to create useful objects, parts, assemblies, and large scale structures. As a term it covers a wide and diverse range of processes, skills, and tools for producing objects on every scale: from huge ships, buildings, and bridges down to precise engine parts and delicate jewelry. The historical roots of metalworking predate recorded history; its use spans cultures, civilizations and millennia. It has evolved from shaping soft, native metals like gold with simple hand tools, through the smelting of ores and hot forging of harder metals like iron, up to highly technical modern processes such as machining and welding. It has been used as an industry, a driver of trade, individual hobbies, and in the creation of art; it can be regarded as both a science and a craft. Modern metalworking processes, though diverse and specialized, can be categorized into one of three broad areas known as forming, cutting, or joining processes. Mo ...
