Wire Brushing
A wire brush is a tool consisting of a brush whose bristles are made of wire, most often steel wire. The steel used is generally a medium- to high-carbon variety and very hard and springy. Other wire brushes feature bristles made from brass or stainless steel, depending on application. Wires in a wire brush can be held together by epoxy, staples, or other binding. Wire brushes usually either have a handle of wood or plastic (for handheld use) or are formed into a wheel for use on angle grinders, bench grinders, pistol-grip drill motors, or other power tools. Uses The wire brush is primarily an abrasive implement, used for cleaning rust and removing paint. It is also used to clean surfaces and to create a better conductive area for attaching electrical connections, such as those between car battery posts and their connectors, should they accumulate a build-up of grime and dirt. When cleaning stainless steel, it is advisable to use a stainless steel bristle wire brush, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drill
A drill is a tool used for making round holes or driving fasteners. It is fitted with a drill bit for making holes, or a screwdriver bit for securing fasteners. Historically, they were powered by hand, and later mains power, but cordless battery-powered drills are proliferating due to increased efficiency and ease of use. Drills are commonly used in woodworking, metalworking, construction, machine tool fabrication, and utility projects. Specially designed versions are made for surgery, dentistry, miniatures, and other applications. History Around 35,000 BC, ''Homo sapiens'' discovered the benefits of the application of rotary tools. This would have rudimentarily consisted of a pointed rock being spun between the hands to bore a hole through another material. This led to the hand drill, a smooth stick, that was sometimes attached to flint point, and was rubbed between the palms. This was used by many ancient civilizations around the world including the Mayans. The ear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metalworking Tools
Metalworking is the process of shaping and reshaping metals in order 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 jewellery. 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 and including 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, cuttin ...

Hand Tools
A hand tool is any tool that is powered by hand rather than a motor. Categories of hand tools include wrenches, pliers, cutters, files, striking tools, struck or hammered tools, screwdrivers, vises, clamps, snips, hacksaws, drills, and knives. Outdoor tools such as garden forks, pruning shears, and rakes are additional forms of hand tools. Portable power tools are not hand tools. History Hand tools have been used by humans since the Stone Age, when stone tools were used for hammering and cutting. During the Bronze Age, tools were made by casting alloys of copper and tin. Bronze tools were sharper and harder than those made of stone. During the Iron Age iron replaced bronze, and tools became even stronger and more durable. The Romans developed tools during this period which are similar to those being produced today. After the Industrial Revolution, most tools were made in factories rather than by craftspeople.

Wire Wheel
Wire wheels, wire-spoked wheels, tension-spoked wheels, or "suspension" wheels are wheels whose rims connect to their hubs by wire spokes. Although these wires are considerably stiffer than a similar diameter wire rope, they function mechanically the same as tensioned flexible wires, keeping the rim true while supporting applied loads. The term ''suspension wheel'' should not be confused with vehicle suspension. Wire wheels are used on most bicycles and are still used on many motorcycles. They were invented by aeronautical engineer George Cayley in 1808. Although Cayley first proposed wire wheels, he did not apply for a patent. The first patent for wire wheels was issued to Theodore Jones of London, England on October 11, 1826. Eugène Meyer of Paris, France was the first person to receive, in 1869, a patent for wire wheels on bicycles. Bicycle wheels were not strong enough for cars until the development of tangentially spoked wheels. They rapidly became well establis ...

Metalworking Hand Tool
Metalworking hand tools are Hand tool, hand tools used in the metalworking field. Types Dollies Dolly (tool), Dollies can be handheld, or mounted on a stake or post. Metal dollies come in a variety of sizes and shapes and are used for all types of hand-forming, planishing (smoothing), and shrinking. Files and rasps File (tool), Files and Rasp, rasps are used to provide a smooth Surface finishing, finish for detail work, and are often used in the Aerospace manufacturer, aerospace industry. Forming bags Forming bags, also known as ''soft dollies'', are usually filled with sand or lead, shot and sewn very tightly out of a top-grade canvas or leather. When used correctly, a forming bag allows the user to "shrink" the metal without marking it. Hammers A wide range of body Hammer, hammers are used in metalworking.

Gastrointestinal Perforation
Gastrointestinal perforation, also known as gastrointestinal rupture, is a hole in the wall of the gastrointestinal tract. The gastrointestinal tract is composed of hollow digestive organs leading from the mouth to the anus. Symptoms of gastrointestinal perforation commonly include severe abdominal pain, nausea, and vomiting. Complications include a painful inflammation of the inner lining of the abdominal wall and sepsis. Perforation may be caused by trauma, bowel obstruction, diverticulitis, stomach ulcers, cancer, or infection. A CT scan is the preferred method of diagnosis; however, free air from a perforation can often be seen on plain X-ray. Perforation anywhere along the gastrointestinal tract typically requires emergency surgery in the form of an exploratory laparotomy. This is usually carried out along with intravenous fluids and antibiotics. Occasionally the hole can be sewn closed while other times a bowel resection is required. Even with maximum treatment t ...

Barbecue Grill
A barbecue grill or barbeque grill (known as a barbecue in Canada and barbecue or barbie in Australia and New Zealand) is a device that cooks food by applying heat from below. There are several varieties of grills, with most falling into one of three categories: gas-fueled, charcoal, or electric. There is debate over which method yields superior results. History in the Americas Grilling has existed in the Americas since pre-colonial times. The Arawak people of South America roasted meat on a wooden structure called a barbacoa in Spanish. For centuries, the term ''barbacoa'' referred to the wooden structure and not the act of grilling, but it was eventually modified to "barbecue". It was also applied to the pit-style cooking techniques now frequently used in the southeastern United States. Barbecue was originally used to slow-cook hogs; however, different ways of preparing food led to regional variations. Over time, other foods were cooked in a similar fashion, with hamburge ...
