Wolfgang Zuckermann
Wolfgang Joachim Zuckermann (11 October 1922 – 30 October 2018) was a German-born American harpsichord maker and writer. He was known for inventing a highly popular kit for constructing new instruments and wrote an influential book, ''The Modern Harpsichord''. As a social activist, he authored books including ''The Mews of London'' and ''The End of the Road''. Early life Zuckermann was born in Berlin to Jewish parents in an academic family, and was named Wolfgang after Goethe and Mozart.Zuckermann (1968) He had an elder brother, Alexander, who later became a city planner and bicycle advocate in Oakland, California, and a younger brother named Michael. At age eight he began studying the cello, an instrument he continued to play in adulthood. The male family members formed a string quartet, with Alexander playing first violin, the father second, Michael viola, and Wolfgang cello. With the advent of the Nazis in Germany, Zuckermann's family had to flee the country; they settled i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Christopher Street
Christopher Street is a street in the West Village neighborhood of the New York City borough of Manhattan. It is the continuation of 9th Street west of Sixth Avenue. It is most notable for the Stonewall Inn, which is located on Christopher Street near the corner of Seventh Avenue South. As a result of the Stonewall riots in 1969, the street became the center of the world's gay rights movement in the late 1970s. To this day, the inn and the street serve as an international symbol of gay pride. Christopher Street is named after Charles Christopher Amos, the owner of the inherited estate which included the location of the street. Amos is also the namesake of nearby Charles Street, and of the former Amos Street, which is now West 10th Street. History Christopher Street is, technically, the oldest street in the West Village, as it ran along the south boundary of Admiral Sir Peter Warren's estate, which abutted the old Greenwich Road (now Greenwich Avenue) to the east and ext ...

High Fidelity
High fidelity (hi-fi or, rarely, HiFi) is the high-quality reproduction of sound. It is popular with audiophiles and home audio enthusiasts. Ideally, high-fidelity equipment has inaudible noise and distortion, and a flat (neutral, uncolored) frequency response within the human hearing range. High fidelity contrasts with the lower-quality " lo-fi" sound produced by inexpensive audio equipment, AM radio, or the inferior quality of sound reproduction that can be heard in recordings made until the late 1940s. History Bell Laboratories began experimenting with various recording techniques in the early 1930s. Performances by Leopold Stokowski and the Philadelphia Orchestra were recorded in 1931 and 1932 using telephone lines between the Academy of Music in Philadelphia and the Bell labs in New Jersey. Some multitrack recordings were made on optical sound film, which led to new advances used primarily by MGM (as early as 1937) and Twentieth Century Fox Film Corporation (as ...

Model Aircraft
A model aircraft is a physical model of an existing or imagined aircraft, and is built typically for display, research, or amusement. Model aircraft are divided into two basic groups: flying and non-flying. Non-flying models are also termed static, display, or shelf models. Aircraft manufacturers and researchers make wind tunnel models for testing aerodynamic properties, for basic research, or for the development of new designs. Sometimes only part of the aircraft is modelled. Static models range from mass-produced toys in white metal or plastic to highly accurate and detailed models produced for museum display and requiring thousands of hours of work. Many are available in kits, typically made of injection-molded polystyrene or resin. Flying models range from simple toy gliders made of sheets of paper, balsa, card stock or foam polystyrene to powered scale models built up from balsa, bamboo sticks, plastic, (including both molded or sheet polystyrene, and styrofoam), m ...

Do It Yourself
"Do it yourself" ("DIY") is the method of building, wikt:modification, modifying, or repairing things by oneself without the direct aid of professionals or certified experts. Academic research has described DIY as behaviors where "individuals use Raw material, raw and semi-raw materials and parts to produce, transform, or reconstruct material possessions, including those drawn from the natural environment (e.g., landscaping)". DIY behavior can be triggered by various motivations previously categorized as market economy, marketplace motivations (economic benefits, lack of product availability, lack of product quality, need for customization), and identity (social science), identity enhancement (Workmanship, craftsmanship, empowerment, community seeking, uniqueness). The term "do-it-yourself" has been associated with consumers since at least 1912 primarily in the domain of home improvement and maintenance activities. The phrase "do it yourself" had come into common usage (in stan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basswood
''Tilia americana'' is a species of tree in the family Malvaceae, native to eastern North America, from southeast Manitoba east to New Brunswick, southwest to northeast Oklahoma, southeast to South Carolina, and west along the Niobrara River to Cherry County, Nebraska. It is the sole representative of its genus in the Western Hemisphere, assuming ''T. caroliniana'' is treated as a subspecies or local ecotype of ''T. americana''. Common names include American basswood and American linden. Description The American basswood is a medium-sized to large deciduous tree reaching a height of exceptionally with a trunk diameter of at maturity. It grows faster than many North American hardwoods, often twice the annual growth rate of American beech and many birch species. Life expectancy is around 200 years, with flowering and seeding generally occurring between 15 and 100 years, though occasionally seed production may start as early as eight years. The crown is domed, the branch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drill Press
A drill press is a Drill, drilling machine suitable for quick and easy drilling of straight holes, Countersink, countersinking or Counterbore, counterboring that are perpendicular to both directions of a table surface. In comparison, it is more difficult and less repeatable to drill perpendicularly with a hand-held drill. Two common variants are the benchtop drill press for mounting to a workbench and the larger floor-standing drill press for mounting to the floor, and they should preferable be securely mounted to prevent them from tipping over. A special variant is the magnetic drilling machine, which is a mobile drilling machine intended to be magnetically clamped during use, and is used to some extent for field repairs and production in industry. Drill presses can be divided into two main types depending on their construction: * Column drill press is a common type characterized by the fact that the drill spindle can be moved up and down Axis of rotation, axially ("along a colu ...

Circular Saw
A circular saw or a buzz saw, is a power-saw using a toothed or Abrasive saw, abrasive disk (mathematics), disc or blade to cut different materials using a rotary motion spinning around an Arbor (tool), arbor. A hole saw and ring saw also use a rotary motion but are different from a circular saw. ''Circular saws'' may also be loosely used for the blade itself. Circular saws were invented in the late 18th century and were in common use in sawmills in the United States by the middle of the 19th century. A circular saw is a tool for cutting many materials such as wood, masonry, plastic, or metal and may be hand-held or mounted to a machine. In woodworking the term "circular saw" refers specifically to the hand-held type and the table saw and Miter saw#Power miter saw, chop saw are other common forms of circular saws. "Skilsaw" and "Skil saw" have become generic trademarks for conventional hand-held circular saws in the United States of America. Circular saw blades are specially d ...

Wood Veneer
Veneer refers to thin slices of wood and sometimes bark that typically are glued onto core panels (typically, wood, particle board or medium-density fiberboard) to produce flat panels such as doors, tops and panels for cabinets, parquet floors and parts of furniture. They are also used in marquetry. Unlike laminates, no two veneer sheets look the same. Plywood consists of three or more layers of veneer. Normally, each is glued with its grain at right angles to adjacent layers for strength. Veneer beading is a thin layer of decorative edging placed around objects, such as jewelry boxes. Veneer is also used to replace decorative papers in wood veneer high pressure laminate. Background Veneering dates back to at least the ancient Egyptians who used expensive and rare wood veneers over cheaper timbers to produce their furniture and sarcophagi. During the Roman Empire, Romans also used veneered work in mass quantities. Production Veneer is obtained either by "peeling ...

Miter Joint
A miter joint (mitre in British English) is a joint made by cutting each of two parts to be joined, across the main surface, usually at a 45° angle, to form a corner, usually to form a 90° angle, though it can comprise any angle greater than 0 degrees. It is called beveling when the angled cut is done on the side, although the resulting joint is still a miter joint. For woodworking, a disadvantage of a miter joint is its weakness, but it can be strengthened with a spline (a thin wafer of wood inserted into a slot, usually arranged with the long grain of the spline across the short grain of the frame timber). There are two common variations of a splined miter joint, one where the spline is long and runs the length of the mating surfaces and another where the spline is perpendicular to the joined edges. Common applications include picture frames, pipes, and molding. Non-perpendicular joints For miter joints occurring at angles other than 90°, for materials of the same ...

Lathe
A lathe () is a machine tool that rotates a workpiece about an axis of rotation to perform various operations such as cutting, sanding, knurling, drilling, deformation, facing, threading and turning, with tools that are applied to the workpiece to create an object with symmetry about that axis. Lathes are used in woodturning, metalworking, metal spinning, thermal spraying, reclamation, and glass-working. Lathes can be used to shape pottery, the best-known design being the Potter's wheel. Most suitably equipped metalworking lathes can also be used to produce most solids of revolution, plane surfaces and screw threads or helices. Ornamental lathes can produce three-dimensional solids of incredible complexity. The workpiece is usually held in place by either one or two ''centers'', at least one of which can typically be moved horizontally to accommodate varying workpiece lengths. Other work-holding methods include clamping the work about the axis of rotation using a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 mandrel, arbor, that is driven by an electric motor (directly, by belt, by cable, or by gears). The drive mechanism is mounted below a table that provides support for the material, usually wood, being cut, with the blade protruding up through the table into the material. In most modern table saws, the table is fixed and the blade position can be adjusted. Moving the blade up or down affects the depth of the cut by controlling how much of the blade is protruding above the table surface. Many saws also have an adjustable angle, where the blade can be tilted relative to the table. Some earlier saws instead had a fixed blade and the table could be adjusted for height (exposure of blade) and angle relative to the blade. Types The general types of table saws are compact, benchtop, jobsite, contractor, hybrid, cabinet, and sliding table saws. Bench ...
