Wingnut (hardware)
A wingnut, wing nut or butterfly nut is a type of nut with two large metal "wings", one on each side, so it can be easily tightened and loosened by hand without tools. A similar fastener with a male thread is known as a wing screw or a wing bolt. Types ASME B18.6.9 classifies wing nuts first by manufacturing method and then by style. * Type A are cold forged or cold formed produced in regular, light and heavy dimensional series. * Type B are hot forged solid nuts available in three different wing styles. * Type C are die cast nuts available in three wing styles with variances between regular and heavy dimensional series * Type D are stamped sheet metal nuts available in three wing styles. Usage Bicycles Before the development of quick release skewers, bicycle wheels were held in place with wingnuts. Drum hardware In a drum kit wingnuts and wingbolts are used extensively. * For securing a suspended cymbal on the mounting bolt of a cymbal stand. * For securing an adjustment ...

Nut (hardware)
A nut is a type of fastener with a threaded hole. Nuts are almost always used in conjunction with a mating bolt to fasten multiple parts together. The two partners are kept together by a combination of their threads' friction (with slight elastic deformation), a slight stretching of the bolt, and compression of the parts to be held together. In applications where vibration or rotation may work a nut loose, various locking mechanisms may be employed: lock washers, jam nuts, eccentric double nuts, specialist adhesive thread-locking fluid such as Loctite, safety pins ( split pins) or lockwire in conjunction with castellated nuts, nylon inserts (nyloc nut), or slightly oval-shaped threads. Square nuts, as well as bolt heads, were the first shape made and used to be the most common largely because they were much easier to manufacture, especially by hand. While rare today due to the reasons stated below for the preference of hexagonal nuts, they are occasionally used in some ...

Bicycle Wing Nuts
A bicycle, also called a pedal cycle, bike or cycle, is a human-powered or motor-powered assisted, pedal-driven, single-track vehicle, having two wheels attached to a frame, one behind the other. A is called a cyclist, or bicyclist. Bicycles were introduced in the 19th century in Europe. By the early 21st century, more than 1 billion were in existence. These numbers far exceed the number of cars, both in total and ranked by the number of individual models produced. They are the principal means of transportation in many regions. They also provide a popular form of recreation, and have been adapted for use as children's toys, general fitness, military and police applications, courier services, bicycle racing, and bicycle stunts. The basic shape and configuration of a typical upright or "safety bicycle", has changed little since the first chain-driven model was developed around 1885. However, many details have been improved, especially since the advent of modern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quick Release Skewer
A quick release skewer is a mechanism for attaching a wheel to a bicycle. It consists of a rod threaded on one end and with a lever operated cam assembly on the other. The rod is inserted into the hollow axle of the wheel, a special nut is threaded on, and the lever is closed to tighten the cam and secure the wheel to the fork. Wheels equipped with quick release mechanisms can be removed from the bicycle frame and replaced without using tools by opening and closing the cam lever, thus more quickly than wheels with solid axles and nuts. On the negative side, a quick-release hub renders a wheel more vulnerable to theft and care must be taken to ensure that the mechanism is properly tightened. Similar quick-release mechanisms are also used to operate seatpost clamps, and the collapsing stem of folding bicycles and kick scooters. History The mechanism was invented in 1927 by Tullio Campagnolo, an Italian bicycle racer. He was frustrated when he attempted to change gears during ...

Bicycle Wheel
A bicycle wheel is a wheel, most commonly a wire wheel, designed for a bicycle. A pair is often called a wheelset, especially in the context of ready built "off the shelf" performance-oriented wheels. Bicycle wheels are typically designed to fit into the frame and fork via dropouts, and hold bicycle tires. Invention The first wheel to use the tension in metal spokes was invented by Sir George Cayley to achieve lightness in his 1853 glider. Construction The first bicycle wheels followed the traditions of carriage building: a wooden hub, a fixed steel axle (the bearings were located in the fork ends), wooden spokes and a shrink fitted iron tire. A typical modern wheel has a metal hub, wire tension spokes and a metal or carbon fiber rim which holds a pneumatic rubber tire. Hub A hub is the center part of a bicycle wheel. It consists of an axle, bearings and a hub shell. The hub shell typically has two machined metal flanges to which spokes can be attached. Hub shells ...

Tom-tom 12x8
A tom drum is a cylindrical drum with no snares, named from the Anglo-Indian and Sinhala language. It was added to the drum kit in the early part of the 20th century. Most toms range in size between in diameter, though floor toms can go as large as . It is not to be confused with a tam-tam, a gong. Design history The drum called "Thammattama", played by the Sinhala people of Sri Lanka, is used in a number of Buddhist rituals in that country. It is commonly heard in Buddhist temples paired along with the reed instrument called horanava. This may be etymologically derived from the Tamil term "Thappattam" or "Thappu", a frame drum associated with South Indian Tamil culture. However, the tom-tom drums on the Western drum set clearly resemble the Sri Lankan version more than the frame drum. The British colonists complained loudly about the noise generated by the "tom-toms" of the natives throughout South Asia. It is likely that the term tom-toms thus comes from their experiences ...

Drum Kit
A drum kit (also called a drum set, trap set, or simply drums) is a collection of drums, cymbals, and other auxiliary percussion instruments set up to be played by one person. The player (drummer) typically holds a pair of matching drumsticks, one in each hand, and uses their feet to operate a foot-controlled hi-hat and bass drum pedal. A standard kit may contain: * A snare drum, mounted on a stand * A bass drum, played with a beater moved by a foot-operated pedal * One or more tom-toms, including rack toms and/or floor toms * One or more cymbals, including a ride cymbal and crash cymbal * Hi-hat cymbals, a pair of cymbals that can be manipulated by a foot-operated pedal The drum kit is a part of the standard rhythm section and is used in many types of popular and traditional music styles, ranging from rock and pop to blues and jazz. __TOC__ History Early development Before the development of the drum set, drums and cymbals used in military and orchestral music sett ...

Suspended Cymbal
Classical suspended cymbal A suspended cymbal is any single cymbal played with a stick or beater rather than struck against another cymbal. Common abbreviations used are "sus. cym.," or "sus. cymb." (with or without the period). Most drum kits contain at least two suspended cymbals: a crash cymbal and a ride cymbal. History The term comes from the modern orchestra, in which the term ''cymbals'' normally refers to a pair of clash cymbals. The first suspended cymbals used in the modern orchestra were one of a pair of orchestral cymbals, supported by hanging it bell upwards (''i.e.'', with concavity opening downward) by its strap. This technique is still used, at times, but has largely been replaced by specialised cymbals with larger mounting holes that can be mounted on a cymbal stand. Occasionally the term ''suspended cymbal'' is still used in the original sense of one of a pair of orchestral cymbals hung by its strap, and this is the usage in older scores and may be the wish ...

Cymbal Stand
A cymbal stand is a stand designed primarily to support a suspended cymbal in a drum kit or percussion section. There are many forms, including: * Straight stands. * Simple boom stands. * Counterweighted boom stands. * Zero-offset boom stands. * Multiple boom stands. The hi-hat stand is a stand for supporting and operating a pair of clash cymbals; The term ''cymbal stand'' in English does not normally include this specialised stand. As well as cymbals, cymbal stands are used to support many other small percussion instruments, and accessories such as practice pads. History Although very ancient examples of single cymbals have been found, all ancient references to cymbals and related instruments have them played in pairs similar to modern clash cymbals. The first modern use of a single cymbal was the orchestral use of a suspended cymbal, using one of a pair suspended by its strap. As suspended cymbals became more common, stands were devised to support them from below. However, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Memory (drum Hardware)
Drum hardware refers to the parts of a drum or drum kit that are used to tension, position, and otherwise support the instruments themselves. Occasionally, the hardware is used percussively as well, the most common example being a rim shot. John Morrison is noted for his drum solos played entirely on a hi-hat stand (and occasionally also on other parts of the kit hardware, adjacent furniture, and audience). __TOC__ Drum parts Rim A drum "hoop" or "rim" may be made of metal, wood, or other materials and is used to hold a drumhead against a drum shell, either with bolts through metal "claws" attached directly to a hoop, or bolts through holes in a flanged or die-cast rim. The bolts, called ''tension rods'', are screwed into threaded "lugs" attached to the drum shell, in order to tighten and tune the drumhead. A drum key is a type of wrench often used to screw the tension rods into the lugs. Spurs/bass drum legs, casings/lugs, and tension rods/tuning screws There are a numbe ...

Drum Key
Drum tuning is the process of adjusting the frequency or pitch of a drum. Although most drums are unpitched instruments, they still have a fundamental pitch and overtones. Drums require tuning for a variety of reasons: to sound good together as a kit, to sound pleasing as an individual drum, to achieve the desired amount of ringing and resonance, and to produce the sound that fits the music. Some drums such as timpani and rototoms are tuned to a definite pitch. Drums are tuned by tightening or loosening the tension rods or ropes, which control the tension on the drumhead. Additional techniques such as muffling may also be used to affect resonance. Styles Snare drum and bass drum Snare drum * The thin, sensitive bottom (resonant) head is generally tuned higher than the batter head, to deaden the tendency for lengthy, ringing resonance. * The resonant head on a 14-inch snare drum is tuned to a range of 330–391 Hz ( E4 to G4), depending on the overall tuning of the drum ...
