Surfboard Shaper
A surfboard shaper is someone who designs and builds surfboards. The process of surfboard shaping has evolved over the years, and the shaper often tailors his or her work to meet the requirements of a client or a certain wave. Surfboard shapers can be independent or work in collaboration with mass-production companies. While originally made from wood, most modern surfboards are now constructed from pre-formed polyurethane or Styrofoam EPS blanks. The surfboard is then shaped using an array of tools, including but not limited to the following: surforms, rasps, grinders, sanders, and planes. After the form of the surfboard is sculpted from the blank, the shaper can lay fiberglass or carbon fiber sheets over the top and bottom of the surfboard, and laminate each sheet with a thermosetting substance, such as epoxy or polyester resin. History Ancient Hawaiian Surfboards There exists very little evidence that pinpoints the exact location of the first surfboard shaper; however, h ...

Coral
Corals are marine invertebrates within the class Anthozoa of the phylum Cnidaria. They typically form compact colonies of many identical individual polyps. Coral species include the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton. A coral "group" is a colony of very many genetically identical polyps. Each polyp is a sac-like animal typically only a few millimeters in diameter and a few centimeters in height. A set of tentacles surround a central mouth opening. Each polyp excretes an exoskeleton near the base. Over many generations, the colony thus creates a skeleton characteristic of the species which can measure up to several meters in size. Individual colonies grow by asexual reproduction of polyps. Corals also breed sexually by spawning: polyps of the same species release gametes simultaneously overnight, often around a full moon. Fertilized eggs form planulae, a mobile early form of the coral polyp which, when m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surfboard Fin
A surfboard fin or skeg is a hydrofoil mounted at the tail of a surfboard or similar board to improve directional stability and control through foot-steering. Fins can provide lateral lift opposed to the water and stabilize the board's trajectory, allowing the surfer to control direction by varying their side-to-side weight distribution. The introduction of fins in the 1930s revolutionized surfing and board design. Surfboard fins may be arrayed in different numbers and configurations, and many different shapes, sizes, and materials are and have been made and used. History Historically, surfboards had no fins; some amount of control was achieved through convex hulls and the surfer dragging a foot in the water. A common problem with these early boards was "sliding ass", in which the tail would slip sideways, usually causing a wipeout. The first fixed fin was introduced by surfing pioneer Tom Blake in 1935. In Waikiki, Blake attached a long, deep metal keel from an abandoned spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyester
Polyester is a category of polymers that contain the ester functional group in every repeat unit of their main chain. As a specific material, it most commonly refers to a type called polyethylene terephthalate (PET). Polyesters include naturally occurring chemicals, such as in plants and insects, as well as synthetics such as polybutyrate. Natural polyesters and a few synthetic ones are biodegradable, but most synthetic polyesters are not. Synthetic polyesters are used extensively in clothing. Polyester fibers are sometimes spun together with natural fibers to produce a cloth with blended properties. Cotton-polyester blends can be strong, wrinkle- and tear-resistant, and reduce shrinking. Synthetic fibers using polyester have high water, wind and environmental resistance compared to plant-derived fibers. They are less Fireproofing, fire-resistant and can melt when ignited. Liquid crystalline polyesters are among the first industrially used liquid crystal polymers. They are use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lamination
Lamination is the technique/process of manufacturing a material in multiple layers, so that the composite material achieves improved strength, stability, sound insulation, appearance, or other properties from the use of the differing materials, such as plastic. A laminate is a permanently assembled object created using heat, pressure, welding, or adhesives. Various coating machines, machine presses and calendering equipment are used. Materials There are different lamination processes, depending primarily on the type or types of materials to be laminated. The materials used in laminates can be identical or different, depending on the process and the object to be laminated. Textile Laminated fabric are widely used in different fields of human activity, including medical and military. Woven fabrics (organic and inorganic based) are usually laminated by different chemical polymers to give them useful properties like chemical resistance, dust, grease, windproofness, photolumin ...

Computer Program
A computer program is a sequence or set of instructions in a programming language for a computer to execute. Computer programs are one component of software, which also includes documentation and other intangible components. A computer program in its human-readable form is called source code. Source code needs another computer program to execute because computers can only execute their native machine instructions. Therefore, source code may be translated to machine instructions using the language's compiler. ( Assembly language programs are translated using an assembler.) The resulting file is called an executable. Alternatively, source code may execute within the language's interpreter. If the executable is requested for execution, then the operating system loads it into memory and starts a process. The central processing unit will soon switch to this process so it can fetch, decode, and then execute each machine instruction. If the source code is requested for execution, ...

Simon Anderson
Simon Anderson (born 7 July 1954) is an Australian competitive surfer, surfboard shaper, and writer. He is credited with the 1980 invention of a three-fin surfboard design, called the "thruster". Early life Anderson grew up in the Northern Beaches area of Sydney with three brothers. His family lived in a house that overlooked Collaroy Beach. In 1977, he won the junior division at the Bells Beach Classic Easter competition and began shaping surfboards in the Sydney suburb of Brookvale. Career In 1977 he won the Bells Beach Classic competition and the Coke Surfabout in Sydney. In October 1980, after seeing a twin fin surfboard with a "trigger point" fin Anderson had the idea for a new version of the existing three fin design which was later dubbed the "thruster". Anderson created a prototype for the "thruster" design and took it on tour with him to Hawaii and California. When he returned to Sydney, he made two more surfboards with similar designs. In 1981, using one of thos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bob McTavish
Bob McTavish (born 1944) is an Australian surfboard designer and member of the surfing hall of fame. Overview Bob McTavish is an Australian surfboard designer who is often credited with the invention of the V-bottom surfboard and was one of a number of pioneering surfer/shapers considered instrumental in the development of shortboard surfing. It has been suggested that without his contributions, the revolutionary nature of shortboard surfing wouldn't have been as effective. Early life Born in Mackay, Queensland in 1944, McTavish began surfing at the age of twelve. He dropped out of school at 15, and moved to Sydney. In 1963 McTavish famously stowed away in an ocean liner bound for Hawaii. He spent 5 weeks in Hawaii before being deported. In the 1970s, McTavish became a Jehovah’s Witness. Surfing McTavish began surfing on a 16-foot (4.8m) plywood paddleboard. McTavish won the Qld State titles in 1964-66 and finished third in the Nationals behind Midget Farrelly an ...

Balsa
''Ochroma pyramidale'', commonly known as the balsa tree, is a large, fast-growing tree native to the Americas. It is the sole member of the genus ''Ochroma''. The tree is famous for its wide usage in woodworking, with the name ''balsa'' being the Spanish word for "raft." A deciduous angiosperm, ''Ochroma pyramidale'' can grow up to 30 m tall, and is classified as a hardwood despite the wood itself being very soft; it is the softest commercial hardwood and is widely used because of its light weight.

Wood Veneer
In woodworking, veneer refers to thin slices of wood and sometimes bark, usually thinner than 3 mm (1/8 inch), 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. 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 HPL. Background Veneer is obtained either by "peeling" the trunk of a tree or by slicing large rectangular blocks of wood known as flitches. The appearance of the grain and figure in wood comes from slicing through the growth rings of a tree and depends upon the angle at which the wood is sliced. There are three main types ...
