A band saw is a saw that can be used for woodworking, metal working, and a variety of other materials. It gets its name from its blade, consisting of a narrow band of toothed metal. This band rides on two large wheels stacked vertically with a space between them. Band saws are particularly useful for cutting irregular shapes. The radius of a curve that can be cut on a particular saw is determined by the width of the band. ...more on Wikipedia about "Band saw"
A belt sander is a machine used to quickly sand down wood and other materials for finishing purposes. It consists of a small motor that pulls a sandpaper belt along. Belt sanders can be either hand-held where the sander is moved over the material or stationary (fixed), where the material is moved on a fixed rotating sanding belt. Stationary belt sanders are often combined with a disc sander. On wood, belt sander have a very agressive action and are normally used only for the beginning stages of the sanding process or used to rapidly remove material. ...more on Wikipedia about "Belt sander"
A blacksmith is person who creates objects from iron or steel by "forging" it; i.e., by using hand tools to hammer, bend, cut and otherwise shape the metal in its non-liquid form. Usually the metal is heated until it glows red or orange as part of the forging process. Blacksmiths create such products as wrought iron gates, grills, railings, light fixtures, furniture, sculpture, tools, decorative and religious items, cooking utensils and weapons. A skilled Blacksmith can make a good looking product that shows skill and ingenuity with the minimum amount of work and energy. ...more on Wikipedia about "Blacksmith"

Bluing is a process in which steel is partially-protected against rust, and is so-named after the blue-black appearance of the resulting protective finish. True gun bluing is a conversion coating resulting from an oxidizing chemical reaction with iron on the surface selectively forming magnetite (Fe304), the black oxide of iron, which occupies the same volume as normal iron. Black oxide provides minimal protection against corrosion, unless also treated with a water-displacing oil. In contrast, the red oxide of iron, Fe2O3 does not occupy the same volume as iron, thereby causing the typical reddish rusting away of iron. Both "cold" and "hot" oxidizing processes are called bluing, but only the "hot" process provides any rust and corrosion resistance, and then only when also treated with an oiled coating. ...more on Wikipedia about "Bluing (steel)"
Bolted joints are one of the most common elements in construction and machine design. They consist of cap screws or studs that capture and join other parts, and are secured with the mating of threads. ...more on Wikipedia about "Bolted joint" Evergreen www.shortopedia.com!!! Metalworking
Cast iron usually refers to grey cast iron, but can mean any of a group of iron-based alloys containing more than 2% carbon (alloys with less carbon are carbon steel by definition). It is made by remelting pig iron, often along with substantial quantities of scrap iron and scrap steel, and taking various steps to remove undesirable contaminants such as phosphorus and sulfur, which weaken the material. Carbon and silicon content are reduced to the desired levels, which may be anywhere from 2% to 3.5% for carbon and 1% to 3% for silicon depending on the application. Other elements are then added to the melt before the final form is produced by casting. ...more on Wikipedia about "Cast iron"
A chisel is a tool for carving and/or cutting a hard material such as wood, stone, or metal. A chisel, typically made of hardened or tempered steel, or more rarely, common steel, consists of a sharpened end (called the blade) attached to a straight handle. The handle and blade of some types of chisels are made in one piece. ...more on Wikipedia about "Chisel"
Clifton Hill Shot Tower is a 80.16 metre tall shot tower on Clifton Hill in Melbourne, Australia. Clifton Hill Shot Tower was built beside Alexandra Parade in 1882 and resembles a chimney. The tower was operated by the Coops family, who also managed Coops Shot Tower, now located within the Melbourne Central shopping centre. ...more on Wikipedia about "Clifton Hill Shot Tower"
A cotter pin (also known as a cotter key) is a metal fastener that is bent during installation, similar to a staple or rivet. Typically made of wire with a half-circular cross section, a new cotter pin (see figure, A) will have its flat inner surfaces touching one another for most of its length, so that it appears to be a split cylinder (figure, D). One tine of the pin is often noticeably longer than the other. Once inserted, the two ends of the pin are bent apart, locking it in place (figure, B). ...more on Wikipedia about "Cotter pin"

Cutting speed is the speed difference between the cutting tool and the surface of the workpiece it is operating on. Cutting speeds are a critical part of productive and economical machining in the field of manufacturing. They are equally important for the safe operation of any applicable machinery, especially in metalworking and woodworking usage. ...more on Wikipedia about "Cutting speed"

Dremel is the name given to rotary tools made by the Robert Bosch Tool Corporation. Similar tools (for example, those manufactured by Craftsman) are also sometimes called Dremels. They are extremely versatile tools and are used extensively by model makers and hobbyists. ...more on Wikipedia about "Dremel"
Extrusion is a manufacturing process where a material, often in the form of a billet, is pushed and/or drawn through a die to create long objects of a fixed cross-section. Hollow sections are usually extruded by placing a pin or mandrel in the die. Extrusion may be continuous (producing indefinitely long material) or semi-continuous (repeatedly producing many shorter pieces). Some materials are hot drawn whilst other may be cold drawn. ...more on Wikipedia about "Extrusion"
Fabrication, when used as an industrial term, applies to the building of machines and structures by cutting, shaping and assembling components made from raw materials, it is a process that generally involves the earlier stages of product manufacture. Small businesses that specialize in metal are called fab shops. ...more on Wikipedia about "Fabrication (metal)"
Graining is the practice of imitating woodgrain on a non-wood surface in order to increase that surface's aesthetic appeal. Graining was common in the 19th century, as people were keen on imitating hard expensive woods by applying a supperficial layer of paint onto soft, inexpensive woods. Graining can be accomplished using either rudimentary tools or highly specialized graining tools. A specialized thick brush used for graining is often called a mottler. It is carried out in layers, with the first layer being a base, and then a second layer applied today usually by means of a sponge. During the 19th century, however, brushes were more usually applied. Graining can also be applied on bricks and brass, as is more common today. ...more on Wikipedia about "Graining"
A hacksaw is a saw for cutting metal. Some of them have pistol grips which keep the hacksaw firm and easy to grip. They also cut in straight lines. It is a fine-tooth saw with a blade under tension in a frame that is used for cutting hard materials (as metal) ...more on Wikipedia about "Hacksaw"
The hardenability of a metal alloy is its capability to be hardened by heat treatment. It should not be confused with hardness, which is a measure of the material's resistance to indentation or scratching. It is an important property for welding, since it is inversely proportional to weldability, that is, the ease of welding a material. ...more on Wikipedia about "Hardenability"
Heat Treatment is a group of manufacturing techniques used to alter the hardness and toughness of a material. The most common application is metallurgical. Heat treatments are also used in the manufacture of many other materials, such as glass. ...more on Wikipedia about "Heat treatment"
Ironwork is any weapon, artwork, utensil or architectural feature made of iron especially used for decoration. There are two main types of ironwork wrought iron and cast iron. While the use of iron dates back as 4000BC, it was the Hittites who first knew how to extract it and develop weapons. Use of iron was mainly utilitarian until the Middle Ages, it became widely used for decoration in the period between the 16th and 19th century. ...more on Wikipedia about "Ironwork"

Knurling is a manufacturing process, typically conducted on a lathe, whereby a visually-attractive diamond-shaped (criss-cross) pattern is cut or rolled into metal. This pattern allows human hands or fingers to get a better grip on the knurled object than would be provided by the originally-smooth metal surface. Occasionally, the knurled pattern is a series of straight ridges or a helix of "straight" ridges rather than the more-usual criss-cross pattern. ...more on Wikipedia about "Knurling"
