Gunsmith
A gunsmith is a person who repairs, modifies, designs, or builds guns. The occupation differs from an armorer, who usually replaces only worn parts in standard firearms. Gunsmiths do modifications and changes to a firearm that may require a very high level of craftsmanship, requiring the skills of a top-level machinist, a very skilled woodworker, and even an engineer. Gunsmiths perform factory-level repairs and renovations to restore a well-used or deteriorated firearms to new condition. They may make alterations to adapt sporting guns to better fit the individual shooter that may require extensive modifications to the firearm's stocks and metal parts. Repairs and redesigns may require fabrication and fitting of unavailable parts and assemblies constructed by smiths themselves. Gunsmiths may also renew metal finishes or apply decorative carvings or engravings to guns. Many gun shops offer gunsmithing service on the premises.

Armourer
Historically, an armourer is a person who makes personal armour, especially plate armour. In modern terms, an armourer is a member of a military or police force who works in an armoury and maintains and repairs small arms and weapons systems, with some duties resembling those of a civilian gunsmith. There is increasing evidence that companies specializing in the manufacture of armoured vehicles or applique armour for application onto vehicles of all types (cars, boats, aircraft) are referring to themselves as armourers; such as the UK company OVIK Crossway - which describes its services as Armourers and Coach Builders. In some ways, this is a reversion back to the original meaning of the term insofar as these companies forge, adapt or integrate physical armour onto platforms in order to protect human life. The title is also used in Olympic sport of fencing (the foil, the épée and the sabre) to refer to those who repair fencers' weaponry, safety equipment, fencing-strips, scor ...

Artisan
An artisan (from french: artisan, it, artigiano) is a skilled craft worker who makes or creates material objects partly or entirely by hand. These objects may be functional or strictly decorative, for example furniture, decorative art, sculpture, clothing, food items, household items and tools and mechanisms such as the handmade clockwork movement of a watchmaker. Artisans practice a craft and may through experience and aptitude reach the expressive levels of an artist. History The adjective "artisanal" is often used in describing hand-processing in contrast to an industrial process, such as in the phrase ''artisanal mining''. Thus, "artisanal" is sometimes used in marketing and advertising as a buzz word to describe or imply some relation with the crafting of handmade food products, such as bread, beverages or cheese. Many of these have traditionally been handmade, rural or pastoral goods but are also now commonly made on a larger scale with automated mechani ...

Gun Shop
A gun shop (also known by various other names such as firearm store and gun store) is a business that sells firearms, such as handguns and long guns, to individuals in an open shopping format. It may also provide repairs for firearms and their parts. Other items such as ammunition, hunting accessories, food, clothing, and even souvenirs may be sold in the store as well. Often having designs reminiscent of other establishments such as department stores and grocery stores, gun shops operate under widely different gun control laws depending on the specific nation, locality, and jurisdiction involved. Some locations may only employ a single gunsmith in a small space, while others might have many individuals working in a large space. Although the advent of online shopping has changed the business of gun stores, the ability for customers to interact face to face with store dealers often is seen as having advantages, examples being personally guiding individuals buying firearms throug ...

Bluing (steel)
Bluing is a passivation process in which steel is partially protected against rust using a black oxide coating. It is named after the blue-black appearance of the resulting protective finish. Bluing involves an electrochemical conversion coating resulting from an oxidizing chemical reaction with iron on the surface selectively forming magnetite (), the black oxide of iron. In comparison, rust, the red oxide of iron (), undergoes an extremely large volume change upon hydration; as a result, the oxide easily flakes off causing the typical reddish rusting away of iron. Black oxide provides minimal protection against corrosion, unless also treated with a water-displacing oil to reduce wetting and galvanic action. In colloquial use, thin coatings of black oxide are often termed 'gun bluing', while heavier coatings are termed 'black oxide'. Both refer to the same chemical process for providing true gun bluing. Overview Various processes are used for the oxidizing process. "Cold ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sear (firearm)
In a firearm, the sear is the part of the trigger mechanism that holds the hammer, striker, or bolt back until the correct amount of pressure has been applied to the trigger, at which point the hammer, striker, or bolt is released to discharge the weapon. The sear may be a separate part or can be a surface incorporated into the trigger. Sear mechanisms are also frequently employed in archery release aids. Description As one firearms manufacturer notes: Sear: A sharp bar, resting in a notch (or in British: "bent") in a hammer (or in British: "tumbler"), holding the hammer back under the tension of the mainspring. When the trigger is pulled, the sear moves out of its notch, releasing the hammer and firing the gun. The term "sear" is sometimes incorrectly used to describe a complete trigger group. Within a trigger group, any number of sears may exist. For example, a Ruger Blackhawk single-action revolver contains one for releasing the hammer. A Ruger Redhawk double/single-ac ...

Proof Test
A proof test is a form of stress test to demonstrate the fitness of a load-bearing structure. An individual proof test may apply only to the unit tested, or to its design in general for mass-produced items. Such a structure is often subjected to loads above that expected in actual use, demonstrating safety and design margin. Proof testing is nominally a nondestructive test, particularly if both design margins and test levels are well-chosen. However, unit failures are by definition considered to have been destroyed for their originally-intended use and load levels. Proof tests may be performed before a new design or unit is allowed to enter service, or perform additional uses, or to verify that an existing unit is still functional as intended.Test intervals for in-service ...

Machining
Machining is a process in which a material (often metal) is cut to a desired final shape and size by a controlled material-removal process. The processes that have this common theme are collectively called subtractive manufacturing, which utilizes machine tools, in contrast to ''additive manufacturing'' (3D printing), which uses controlled addition of material. Machining is a part of the manufacture of many metal products, but it can also be used on other materials such as wood, plastic, ceramic, and composite material. A person who specializes in machining is called a machinist. A room, building, or company where machining is done is called a machine shop. Much of modern-day machining is carried out by computer numerical control (CNC), in which computers are used to control the movement and operation of the mills, lathes, and other cutting machines. This increases efficiency, as the CNC machine runs unmanned therefore reducing labour costs for machine shops. History and ter ...

Browning (chemical Process)
Browning is the process of food turning brown due to the chemical reactions that take place within. The process of browning is one of the chemical reactions that take place in food chemistry and represents an interesting research topic regarding health, nutrition, and food technology. Though there are many different ways food chemically changes over time, browning in particular falls into two main categories: enzymatic versus non-enzymatic browning processes. Browning has many important implications on the food industry relating to nutrition, technology, and economic cost. Researchers are especially interested in studying the control (inhibition) of browning and the different methods that can be employed to maximize this inhibition and ultimately prolong the shelf life of food. Enzymatic browning Enzymatic browning is one of the most important reactions that takes place in most fruits and vegetables as well as in seafood. These processes affect the taste, color, and value of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Parkerizing
Phosphate conversion coating is a chemical treatment applied to steel parts that creates a thin adhering layer of iron, zinc, or manganese phosphates, to achieve corrosion resistance, lubrication, or as a foundation for subsequent coatings or painting. It is one of the most common types of conversion coating. The process is also called phosphate coating, phosphatization, phosphatizing, or phosphating. It is also known by the trade name Parkerizing, especially when applied to firearms and other military equipment. A phosphate coating is usually obtained by applying to the steel part a dilute solution of phosphoric acid, possibly with soluble iron, zinc, and/or manganese salts. The solution may be applied by sponging, spraying, or immersion. Phosphate conversion coatings can also be used on aluminium, zinc, cadmium, silver and tin. Types The main types of phosphate coatings are manganese, iron, and zinc. * Manganese phosphate coatings are used both for corrosion resistanc ...

Gun Safety
Gun safety is the study and practice of using, transporting, storing and disposing of firearms and ammunition, including the training of gun users, the design of weapons, and formal and informal regulation of gun production, distribution, and usage, for the purpose of avoiding unintentional injury, illness, or death. This includes mishaps like accidental discharge, negligent discharge, and firearm malfunctions, as well as secondary risks like hearing loss, lead poisoning from bullets, and pollution from other hazardous materials in propellants and cartridges. There were 47,000 unintentional firearm deaths worldwide in 2013. History Accidental explosions of stored gunpowder date to the 13th century in Yangzhou, China. Early handheld muskets using matchlock or wheel lock mechanisms were limited by poor reliability and the risk of accidental discharge, which was improved somewhat by the introduction of the flintlock, though unintentional firing continued to be a serious draw ...

Chisel
A chisel is a tool with a characteristically shaped cutting edge (such that wood chisels have lent part of their name to a particular grind) of blade on its end, for carving or cutting a hard material such as wood, stone, or metal by hand, struck with a mallet, or mechanical power. The handle and blade of some types of chisel are made of metal or of wood with a sharp edge in it. Chiselling use involves forcing the blade into some material to cut it. The driving force may be applied by pushing by hand, or by using a mallet or hammer. In industrial use, a hydraulic ram or falling weight ('trip hammer') may be used to drive a chisel into the material. A gouge (one type of chisel) serves to carve small pieces from the material, particularly in woodworking, woodturning and sculpture. Gouges most frequently produce concave surfaces. A gouge typically has a 'U'-shaped cross-section. Etymology ''Chisel'' comes from the Old French ''cisel'', modern ''ciseau'', Late Latin ''cisel ...
