Vise
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 split ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Woodworking Vise
A woodworking vise is a type of vise adapted to the various needs of woodworkers and woodworking. Several types have evolved to meet differing primary functions, falling under the general categories of #Front vise types, front and #End vise types, end vises, reflecting their positions on a workbench. Bench location There are two main locations for a vise (''vice'' in UK English sp.) or vises on a workbench: on the front, a workbench's long face, known as a "front" ("face", or "shoulder") vise, and on the end, known as a "tail" vise. Either or both may be mounted on the right side of their face to allow a workpiece extending from them to be more easily worked by a right-handed person, though a common arrangement is with the front vise mounted on the left of a long side and the tail on the right side of the diagonally opposite end. Aids A woodworking vise holds work in its jaws, or compressed against a bench dog or holdfast (tool), holdfast. Holes to receive these stops or c ...

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 ...

Bench Dog
A bench dog is a removable clamp used on a woodworking workbench to hold an item fast while being worked. It is characteristically used in concert with an adjustable dog on a bench vise, allowing an item compressed between the two to be held fast on each end, and if offset in both directions. A dog in general is something which holds. Technically, a simple peg installed in a ''dog hole'' in the top of a bench is a basic form of bench dog, though those dogs which clamp an item fast to the bench rather than merely sandwich it between itself and a dog on a vise, known as holdfasts, are most common. Dog holes are arranged in a line perpendicular to the jaws of a vise, typically in intervals of four to six inches. Some workbenches have a second row parallel to the vise jaws, to allow broad or long items to be held fast in two directions, as well as to the benchtop itself when using one or more holdfasts. Bench dogs may be square or round. Round dog holes are easier to make but d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vise Grip
Locking pliers (also called Vise-Grips, Mole wrench or Mole grips) are pliers that can be locked into position, using an "over-center" cam action. Locking pliers are available with many different jaw styles, such as needle-nose pliers, wrenches, clamps and various shapes to fix metal parts for welding. They also come in many sizes. History The first locking pliers, with the trade name Vise-Grip, were invented by William S. Petersen in De Witt, Nebraska, United States in 1924. Later, in 1955, in the United Kingdom, M K Mole and Son, a hand tool manufacturing company, under the managing direction of Thomas Coughtrie, began making nearly identical pliers. Etymology In the United States, the brand name "''Vise-Grips''" is close to a generic name for this type of pliers. The same is true in the United Kingdom of the brand name "''Mole Wrench''". The spelling "''vise''" is mentioned in Samuel Johnson's 1755 dictionary. This spelling is orthodox in the United States. The spel ...

Drill Presses
A drill press is a drilling machine suitable for quick and easy drilling of straight holes, countersinking or counterboring that are perpendicular to both directions of a table surface. In comparison, it is more difficult and less repeatable to drill perpendicularly with a hand-held drill. Two common variants are the benchtop drill press for mounting to a workbench and the larger floor-standing drill press for mounting to the floor, and they should preferable be securely mounted to prevent them from tipping over. A special variant is the magnetic drilling machine, which is a mobile drilling machine intended to be magnetically clamped during use, and is used to some extent for field repairs and production in industry. Drill presses can be divided into two main types depending on their construction: * Column drill press is a common type characterized by the fact that the drill spindle can be moved up and down axially ("along a column"), and has a height-adjustable table, usuall ...

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 ...

Buttress Thread
Buttress thread forms, also known as sawtooth thread forms or breech-lock thread forms. are screw thread profiles with an asymmetric shape, having one square face and the other slanted. They are most commonly used for leadscrews where the load is principally applied in one direction. The asymmetric thread form allows the thread to have low friction and withstand greater loads than other forms in one direction, but at the cost of higher friction and inferior load bearing in the opposite direction. They are typically easier to manufacture than square thread forms but offer higher load capacity than equivalently sized trapezoidal thread forms. Buttress thread characteristics The buttress thread form is designed to handle axial thrust applied principally in one direction. The load-bearing thread face is perpendicular or at a slight slant (usually no greater than 7°) to the screw axis. The trailing face is slanted, often at 45°. The resulting thread form has the same low frictio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acme Thread
Trapezoidal thread forms are screw thread profiles with trapezoidal outlines. They are the most common forms used for leadscrews (power screws). They offer high strength and ease of manufacture. They are typically found where large loads are required, as in a vise or the leadscrew of a lathe. Standardized variations include multiple-start threads, left-hand threads, and self-centering threads (which are less likely to bind under lateral forces). The original trapezoidal thread form, and still probably the one most commonly encountered worldwide, with a 29° thread angle, is the Acme thread form ( ). The Acme thread was developed in 1894 as a profile well suited to power screws that has various advantages over the square thread,See: * Simpson, John and Proffitt, Michael, ed.s, "acme", ''Oxford English Dictionary: Additions Series'', vol. 3 (Oxford, England: Oxford University Press, 1997)p. 10.* The Acme thread was proposed by Albert Man Powell, then president of the Powell ...

Anvil
An anvil is a metalworking tool consisting of a large block of metal (usually Forging, forged or Steel casting, cast steel), with a flattened top surface, upon which another object is struck (or "worked"). Anvils are massive because the higher their inertia, the more efficiently they cause the energy of striking tools to be transferred to the work piece. In most cases the anvil is used as a forge, forging tool. Before the advent of modern welding technology, it was the primary tool of metal workers. The great majority of modern anvils are made of cast steel that has been heat treated by either Case-hardening, flame or Induction_hardening, electric induction. Inexpensive anvils have been made of cast iron and low-quality steel, but are considered unsuitable for serious use, as they deform and lack rebound when struck. The largest single piece tool steel anvil that is heat treated is 1600 pounds. This anvil was made in 2023 by Oak Lawn Blacksmith. There are larger anvils tha ...

Plastic
Plastics are a wide range of synthetic polymers, synthetic or Semisynthesis, semisynthetic materials composed primarily of Polymer, polymers. Their defining characteristic, Plasticity (physics), plasticity, allows them to be Injection moulding, molded, Extrusion, extruded, or Compression molding, pressed into a diverse range of solid forms. This adaptability, combined with a wide range of other properties such as low weight, durability, flexibility, chemical resistance, low toxicity, and low-cost production, has led to their widespread use around the world. While most plastics are produced from natural gas and petroleum, a growing minority are produced from renewable resources like polylactic acid. Between 1950 and 2017, 9.2 billion metric tons of plastic are estimated to have been made, with more than half of this amount being produced since 2004. In 2023 alone, preliminary figures indicate that over 400 million metric tons of plastic were produced worldwide. If global trends ...

Machinist
A machinist is a tradesperson or trained professional who operates machine tools, and has the ability to set up tools such as milling machines, grinders, lathes, and drilling machines. A competent machinist will generally have a strong mechanical aptitude, the ability to correctly use precision measuring instruments and to interpret blueprints, and a working knowledge of the proper parameters required for successfully utilizing the various tools commonly used in machining operations. CNC (computer numerical control) comprises one of the most recent advances in manufacturing, in which a machinist uses specialized software to generate programmatic instructions (most commonly G-code) which are in turn interpreted by the machine to make components for a wide variety of industries. CNC programming is a skilled position which requires knowledge of math, speeds and feeds, machine tooling, work holding, and the different ways various materials react to stress and heat in the machining ...

Copper
Copper is a chemical element; it has symbol Cu (from Latin ) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable, unalloyed metallic form. This means that copper is a native metal. This led to very early human use in several regions, from . Thousands of years later, it was the first metal to be smelted from sulfide ores, ; the first metal to be cast into a shape in a mold, ; and the first metal to be purposely alloyed with another metal, tin, to create bronze, ...
