Miter Saw
A miter saw or mitre saw is a saw used to make accurate crosscuts and miters in a workpiece by positioning a mounted blade onto a board. A miter saw in its earliest form was composed of a back saw in a miter box, but in modern implementation consists of a powered circular saw that can be positioned at a variety of angles and lowered onto a board positioned against a backstop called the fence. Powered miter saws also cut bevels into a work piece by adjusting the vertical tilt axis of upper portion of the machine while the table lays flat horizontally. A miter saw for which the axis can be tilted in a single direction is known as a single compound miter saw. If the axis can tilt both left and right, it is known as a double bevel compound miter saw. Some are equipped with a sliding rail system or have a pivot arm to cut wider work pieces when laid flat on the table of the saw and flush against the fence. This is known as a sliding compound miter saw. Miter saws are primarily used ...

Mitre Saw White
The mitre (Commonwealth English) (; Greek: μίτρα, "headband" or "turban") or miter (American English; American and British English spelling differences#-re, -er, see spelling differences), is a type of headgear now known as the traditional, ceremonial headdress of bishops and certain abbots in traditional Christianity. Mitres are worn in the Catholic Church, Eastern Orthodox Church, Oriental Orthodox Churches, the Anglican Communion, some Lutheranism, Lutheran churches, for important ceremonies, by the Metropolitan of the Malankara Mar Thoma Syrian Church, and also, in the Catholic Church, all Cardinal (Catholic Church)#Cardinals who are not bishops, cardinals, whether or not bishops, and some Eastern Orthodox Archpriest#Eastern Christianity, archpriests. Etymology μίτρα, ''mítra'' (Ionic Greek, Ionic μίτρη, ''mítrē'') is Greek language, Greek, and means a piece of armour, usually a metal guard worn around the waist and under a cuirass, as mentioned in Homer ...

Kerf
A saw is a tool consisting of a tough blade, wire, or chain with a hard toothed edge. It is used to cut through material, very often wood, though sometimes metal or stone. The cut is made by placing the toothed edge against the material and moving it forcefully forth and less vigorously back or continuously forward. This force may be applied by hand, or powered by steam, water, electricity or other power source. An abrasive saw has a powered circular blade designed to cut through metal or ceramic. Terminology * Abrasive saw: A saw that cuts with an abrasive disc or band, rather than a toothed blade. * Back: the edge opposite the toothed edge. * Fleam: The angle of the faces of the teeth relative to a line perpendicular to the face of the saw. * Gullet: The valley between the points of the teeth. * Heel: The end closest to the handle. * Kerf: The narrow channel left behind by the saw and (relatedly) the measure of its width. The kerf depends on several factors: the width of ...

Metalworking Hand Tools
Metalworking hand tools are hand tools that are used in the metalworking field. Hand tools are powered solely by the operator. Slapper Both metal and wood slappers are used for metalworking. Generally wood slappers are covered with a leather-face. Slappers can be used to shrink, contour, and planish (smooth) the panel without leaving rough marks to clean up. The salapper controls more surface with each blow than a hammer can and is very easy to use because it has the same angle of attack as a body hammer. This means the user does not need to change their arm and hand position when moving from hammer to slapper. The slapper can be far more effective than the hammer for shrinking because its leverage gives greater mechanical advantage over the rough spots. The slapper is great for working metal over a T-stake or for gouging and planishing. A good slapper can make radius bends and crowns quite well. A slapper works well with forming stakes and post dollies for lightly planishing and p ...

Metalworking Cutting Tools
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 ...

Table Saw
A table saw (also known as a sawbench or bench saw in England) is a woodworking tool, consisting of a circular saw blade, mounted on an arbor, that is driven by an electric motor (either directly, by belt, or by gears). The blade protrudes through the top of a table, which provides support for the material, usually wood, being cut. In most modern table saws, the depth of the cut is varied by moving the blade up and down: the higher the blade protrudes above the table, the deeper the cut that is made in the material. In some early table saws, the blade and arbor were fixed, and the table was moved up and down to expose more or less of the blade. The angle of cut is controlled by adjusting the angle of blade. Some earlier saws angled the table to control the cut angle. Types The general types of table saws are compact, benchtop, jobsite, contractor, hybrid, cabinet, and sliding table saws. Benchtop Benchtop table saws are lightweight and are designed to be placed on a table o ...

Hack Saw
A hacksaw is a fine-toothed saw, originally and mainly made for cutting metal. The equivalent saw for cutting wood is usually called a bow saw. Most hacksaws are hand saws with a C-shaped walking frame that holds a blade under tension. Such hacksaws have a handle, usually a pistol grip, with pins for attaching a narrow disposable blade. The frames may also be adjustable to accommodate blades of different sizes. A screw or other mechanism is used to put the thin blade under tension. On hacksaws, as with most frame saws, the blade can be mounted with the teeth facing toward or away from the handle, resulting in cutting action on either the push or pull stroke. In normal use, cutting vertically downwards with work held in a bench vise, hacksaw blades are set to be facing forwards. History While saws for cutting metal had been in use for many years, significant improvements in longevity and efficiency were made in the 1880s by Max Flower-Nash. George N. Clemson, a founder of ...

Radial Arm Saw
A radial arm saw is a cutting machine consisting of a circular saw mounted on a sliding horizontal arm. Invented by Raymond DeWalt in 1922, the radial arm saw was the primary tool used for cutting long pieces of stock to length until the introduction of the power miter saw in the 1970s. In addition to making length cuts, a radial arm saw may be configured with a dado blade to create cuts for dado, rabbet or half lap joints. In addition some radial arm saws allow the blade to be turned parallel to the back fence, allowing a rip cut to be performed. Origins Unlike most types of woodworking machinery, the radial arm saw has a clear genesis: it was invented by Raymond DeWalt of Leola, Pennsylvania. DeWalt applied for patents in 1923, which were issued in 1925 (US Patent 1,528,536). DeWalt and others subsequently patented many variations on the original, but DeWalt's original design (sold under the moniker Wonder Worker) remained the most successful: a circular saw blade directly ...

Backsaw
A backsaw is any hand saw which has a stiffening rib on the edge opposite the cutting edge, enabling better control and more precise cutting than with other types of saws. Backsaws are normally used in woodworking for precise work, such as cutting dovetails, mitres, or tenons in cabinetry and joinery. Because of the stiffening rib, backsaws are limited in the depth to which they can cut. Backsaws usually have relatively closely spaced teeth, often with little or no set. Types of backsaws Backsaws include the tenon saw, the dovetail saw, and the (United Kingdom) sash saw 1. Tenon and dovetail saws usually have a pistol grip style handle which may be open or closed at the bottom. Different types of backsaw include: * Mitre saw – often referred to as a large backsaw (20–30 inches or 60–90 cm) used either in a wooden or metal mitre box or in a metal frame which allowed cutting mitres of any specified angle. Note that not all mitre saws are backsaws, and the electric ...

Diamond Tools
A diamond tool is a cutting tool with diamond grains fixed on the functional parts of the tool via a bonding material or another method. As diamond is a superhard material, diamond tools have many advantages as compared with tools made with common abrasives such as corundum and silicon carbide. History In '' Natural History'', Pliny wrote "When an '' adamas'' is successfully broken it disintegrates into splinters so small as to be scarcely visible. These are much sought after by engravers of gems and are inserted by them into iron tools because they make hollows in the hardest materials without difficulty." Advantages Diamond is one of the hardest natural materials on earth; much harder than corundum and silicon carbide. Diamond also has high strength, good wear resistance, and a low friction coefficient. So when used as an abrasive, it has many obvious advantages over many other common abrasives. Advantages of diamond grinding tools Diamond can be used to make grinding tools, wh ...

Miter Box
A mitre box or miter box (American English) is a wood working appliance used to guide a hand saw for making precise cuts, usually 45° mitre cuts. Traditional mitre boxes are simple in construction and made of wood, while adjustable mitre boxes are made of metal and can be adjusted for cutting any angle from 45° to 90°. In many workshops and jobsites mitre boxes have been superseded by the powered mitre saw, however advocates for mitre boxes argue that they are more accurate, safer, quieter, cheaper, and take up less space than a powered mitre saw. Description Basic mitre box The most common and simplest form of a mitre box is a U-shaped block made from wood, plastic or aluminium, which is open at the top and the ends. The box is made wide enough to accommodate the width of the workpieces to be cut. Slots are cut in the walls of the box at the precise angle at which the cut is to be made. These slots provide the guide for the saw to follow. Most commonly, the slots in th ...

Arbor (tool)
A mandrel, mandril, or arbor is a gently tapered cylinder against which material can be forged or shaped (e.g., a ring mandrel - also called a triblet - used by jewelers to increase the diameter of a wedding ring), or a flanged or tapered or threaded bar that grips a workpiece to be machined in a lathe. A flanged mandrel is a parallel bar of a specific diameter with an integral flange towards one end, and threaded at the opposite end. Work is gripped between the flange and a nut on the thread. A tapered mandrel (often called a plain mandrel) has a taper of approximately 0.005 inches per foot and is designed to hold work by being driven into an accurate hole on the work, gripping the work by friction. A threaded mandrel may have a male or female thread, and work which has an identical thread is screwed onto the mandrel. On a lathe, mandrels are commonly mounted between centres and driven by a lathe dog (typically the flanged or tapered mandrels), but may also be gripped in a c ...

Vacuum Cleaner
A vacuum cleaner, also known simply as a vacuum or a hoover, is a device that causes suction in order to remove dirt from floors, upholstery, draperies, and other surfaces. It is generally electrically driven. The dirt is collected by either a dustbag or a cyclone for later disposal. Vacuum cleaners, which are used in homes as well as in industry, exist in a variety of sizes and models—small battery-powered hand-held devices, wheeled canister models for home use, domestic central vacuum cleaners, huge stationary industrial appliances that can handle several hundred litres of dirt before being emptied, and self-propelled vacuum trucks for recovery of large spills or removal of contaminated soil. Specialized shop vacuums can be used to suck up both solid matter and liquids. Name Although ''vacuum cleaner'' and the short form ''vacuum'' are neutral names, in some countries (UK, Ireland) ''hoover'' is used instead as a genericized trademark, and as a verb. The name comes from t ...
