Shim (engineering)
A shim is a thin and often tapered or wedged piece of material, used to fill small gaps or spaces between objects. Shims are typically used in order to support, adjust for better fit, or provide a level surface. Shims may also be used as spacers to fill gaps between parts subject to wear. Materials Many materials make suitable shim stock (also often styled shimstock), or base material, depending on the context: wood, stone, plastic, metal, or even paper (e.g., when used under a table leg to level the table surface). High quality shim stock such as laminated shims can be bought commercially, but shims are often created ad hoc from whatever material is immediately available. Laminated shim stock is stacked foil that can be peeled off one layer at a time to adjust the thickness of the shim. Applications In automobiles, shims are commonly used to adjust the clearance or space between two parts. For example, shims are inserted into or under bucket tappets to control valve ...

Luthiery
A luthier ( ; ) is a craftsperson who builds or repairs string instruments. Etymology The word ' is originally French and comes from ''luth'', the French word for "lute". The term was originally used for makers of lutes, but it came to be used in French for makers of most bowed and plucked stringed instruments such as members of the violin family (including violas, cellos, and double basses) and guitars. Luthiers, however, do not make harps or pianos; these require different skills and construction methods because their strings are secured to a frame. Craft The craft of luthiers, lutherie (rarely called "luthiery", but this often refers to stringed instruments other than those in the violin family), is commonly divided into the two main categories of makers of stringed instruments that are plucked or strummed and makers of stringed instruments that are bowed. Since bowed instruments require a bow, the second category includes a subtype known as a bow maker or archetier ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Hardwood
Hardwood is wood from Flowering plant, angiosperm trees. These are usually found in broad-leaved temperate and tropical forests. In temperate and boreal ecosystem, boreal latitudes they are mostly deciduous, but in tropics and subtropics mostly evergreen. Hardwood (which comes from angiosperm trees) contrasts with softwood (which is from gymnosperm trees). Characteristics Hardwoods are produced by Flowering plant, angiosperm trees that reproduce by flowers, and have broad leaves. Many species are deciduous. Those of temperate regions lose their leaves every autumn as temperatures fall and are dormant in the winter, but those of tropical regions may shed their leaves in response to seasonal or sporadic periods of drought. Hardwood from deciduous species, such as oak, normally shows annual dendrochronology, growth rings, but these may be absent in some tropical timber, tropical hardwoods. Hardwoods have a more complex structure than softwoods and are often much slower growing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Plectrum
A plectrum is a small flat tool used for plucking or strumming of a stringed instrument. For hand-held instruments such as guitars and mandolins, the plectrum is often called a pick and is held as a separate tool in the player's hand. In harpsichords, the plectra are attached to the jack mechanism. Plectra wielded by hand Guitars and similar instruments A plectrum for electric guitars, acoustic guitars, bass guitars and mandolins is typically a thin piece of plastic or other material most commonly shaped like a pointed teardrop or triangle, though the size, gauge, shape and width may vary considerably. Banjo and guitar players may wear a metal or plastic thumb pick mounted on a ring, and bluegrass banjo players often wear metal or plastic fingerpicks on their fingertips. Many guitarists use fingerpicks as well. Guitar picks are made of a variety of materials, including celluloid, metal, and rarely other exotic materials such as turtle shell, but today delrin (a synthetic ...

ISO/IEC 7810
International Organization for Standardization, ISO/International Electrotechnical Commission, IEC 7810 ''Identification cards — Physical characteristics'' is an international standard that defines the physical characteristics for identification cards. The characteristics specified include: * Physical dimensions * Resistance to bending, chemicals, temperature, and humidity * Toxicity The standard includes test methods for resistance to heat. Card sizes The standard defines four card sizes: ID-1, ID-2, ID-3 and ID-000. All card sizes have a thickness of , i.e. minimum and maximum . The standard defines both metric and imperial measurements, noting that: ID-1 The ID-1 format specifies a size of and rounded corners with a radius of 2.88–3.48 mm (about in). This format is also referred to as ''CR-80'' and, for travel documents, ''TD1''. It is commonly used for payment cards (Automated teller machine, ATM cards, credit cards, debit cards, etc.).

Business Card
Business cards are card stock, cards bearing business information about a company or individual. They are shared during formal introductions as a convenience and a memory aid. A business card typically includes the giver's name, types of companies, company or business affiliation (usually with a logo) and contact information such as address (geography), street addresses, telephone number(s), fax number, e-mail addresses and website. Before wide use of the internet, business cards also included telex details. Now they may include social media addresses such as Facebook, LinkedIn and Twitter. Traditionally, many cards were simple black text on white stock, and the distinctive look and feel of cards printed from an engraved plate was a desirable sign of professionalism. In the late 20th century, technological advances drove changes in style, and today a professional business card will often include one or more aspects of striking visual design.

Sanding Paper
file:Schleifpapier verschiedene Sorten.jpg, upright=1.35, Sheets of sandpaper with different grit sizes (40 (coarse), 80, 150, 240, 600 (fine)) Sandpaper, also known as coated abrasive or emery paper, is a type of material that consists of sheets of paper or cloth with an abrasive substance glued to one face. In the modern manufacture of these products, sand and glass have been replaced by other abrasives such as aluminium oxide or silicon carbide. It is common to use the name of the abrasive when describing the paper, e.g. "aluminium oxide paper", or "silicon carbide paper". There are many varieties of sandpaper, with variations in the paper or backing, the material used for the grit, grit size, and the bond. Sandpaper is produced in a range of grit sizes and is used to remove material from surfaces, whether to make them smoother (for example, in house painter and decorator, painting and wood finishing), to remove a layer of material (such as old paint), or sometimes to make th ...

Neck (music)
The neck is the part of certain string instruments that projects from the main body and is the base of the fingerboard, where the fingers are placed to stop the strings at different pitches. Guitars, banjos, ukuleles, lutes, the violin family, and the mandolin family are examples of instruments which have necks. Necks are also an integral part of certain woodwind instruments, such as the saxophone. The word for neck also sometimes appears in other languages in musical instructions. The terms include ''manche'' (French), ''manico'' (Italian), and ''Hals'' (German). Guitar The neck of a guitar includes the guitar's frets, fretboard, tuners, headstock, and truss rod. The wood used to make the fretboard will usually differ from the wood in the rest of the neck. The bending stress on the neck is considerable, particularly when heavier gauge strings are used, and the ability of the neck to resist bending is important to the guitar's ability to hold a constant pitch duri ...

Banjo
The banjo is a stringed instrument with a thin membrane stretched over a frame or cavity to form a resonator. The membrane is typically circular, and in modern forms is usually made of plastic, where early membranes were made of animal skin. Early forms of the instrument were fashioned by African Americans and had African antecedents. In the 19th century, interest in the instrument was spread across the United States and United Kingdom by traveling shows of the 19th-century minstrel show fad, followed by mass production and mail-order sales, including instructional books. The inexpensive or home-made banjo remained part of rural folk culture, but five-string and four-string banjos also became popular for home parlor music entertainment, college music clubs, and early 20th century jazz bands. By the early 20th century, the banjo was most frequently associated with folk, cowboy music, and country music. By mid-century it had come to be strongly associated with bluegrass. Eventu ...

Ukulele
The ukulele ( ; ); also called a uke (informally), is a member of the lute (ancient guitar) family of instruments. The ukulele is of Portuguese origin and was popularized in Hawaii. The tone and volume of the instrument vary with size and construction. Ukuleles commonly come in four sizes: soprano, concert, tenor, and baritone. Ukuleles generally have four nylon strings tuned to GCEA. They have 16–22 frets depending on the size. History Developed in the 1880s, the ukulele is based on several small, guitar-like instruments of Portuguese origin, the , and , introduced to the Hawaiian Islands by Portuguese immigrants from Madeira, the Azores, and Cape Verde. Three immigrants in particular, Madeiran cabinet makers Manuel Nunes, José do Espírito Santo, and Augusto Dias, are generally credited as the first ukulele makers. Two weeks after they disembarked from the SS ''Ravenscrag'' in late August 1879, the '' Hawaiian Gazette'' reported that "Madeira Islanders recently arriv ...

Mandolin
A mandolin (, ; literally "small mandola") is a Chordophone, stringed musical instrument in the lute family and is generally Plucked string instrument, plucked with a plectrum, pick. It most commonly has four Course (music), courses of doubled Strings (music), strings tuned in unison, thus giving a total of eight strings. A variety of string types are used, with steel strings being the most common and usually the least expensive. The courses are typically tuned in an interval of perfect fifths, with the same tuning as a violin (G3, D4, A4, E5). Also, like the violin, it is the soprano member of a Family (musical instruments), family that includes the mandola, octave mandolin, mandocello and mandobass. There are many styles of mandolin, but the three most common types are the ''Neapolitan'' or ''round-backed'' mandolin, the ''archtop'' mandolin and the ''flat-backed'' mandolin.

Guitar
The guitar is a stringed musical instrument that is usually fretted (with Fretless guitar, some exceptions) and typically has six or Twelve-string guitar, twelve strings. It is usually held flat against the player's body and played by strumming or Plucked string instrument, plucking the strings with the dominant hand, while simultaneously pressing selected strings against frets with the fingers of the opposite hand. A guitar pick may also be used to strike the strings. The sound of the guitar is projected either Acoustics, acoustically, by means of a resonant hollow chamber on the guitar, or Amplified music, amplified by an electronic Pickup (music technology), pickup and an guitar amplifier, amplifier. The guitar is classified as a chordophone, meaning the sound is produced by a vibrating string stretched between two fixed points. Historically, a guitar was constructed from wood, with its strings made of catgut. Steel guitar strings were introduced near the end of the nineteen ...
