Sail-maker
A sailmaker makes and repairs sails for sailboats, kites, hang gliders, wind art, architectural sails, or other structures using sails. A sailmaker typically works on shore in a sail loft; the sail loft has other sailmakers. Large ocean-going sailing ships often had sailmakers in the crew. The sailmaker maintained and repaired sails. This required knowledge of the sailmaker's craft and the tools of the sailmakers loft on shore. Today, one of a sailmaker's important jobs is to teach people how to set and trim their sails to get the most out of them. Sometimes a sailmaker will accompany the client out on the water and adjust the sails. The modern sailmaker uses computer-aided design and manufacturing tools. Computer graphics allow the sailmaker to produce a "lines drawing" of the sail. Once the design is complete, the sailmaker can now use a low-power laser to cut the material to the exact shape. Broadseam CFD Sailmakers have recently started using Computational fluid dynamics ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USS Monongahela (1862)
USS ''Monongahela'' was a barkentine–rigged screw sloop-of-war that served in the Union Navy during the American Civil War. Her task was to participate in the Union blockade of the Confederate States of America. Post-war, she continued serving her country in various roles, such as that of a storeship and schoolship. Service history American Civil War ''Monongahela''—the first United States Navy ship to bear that name—was built by the Philadelphia Navy Yard and was launched on July 10, 1862; sponsored by Ms. Emily V. Hoover, daughter of Naval Constructor Hoover who superintended the ship's construction; and commissioned on January 15, 1863, Captain (naval), Captain James P. McKinstry in command. Initially assigned to the North Atlantic Squadron, ''Monongahela'' sailed instead to reinforce Rear admiral (United States), Rear Admiral David G.

Thimble
A thimble is a small pitted cup worn on the finger that protects it from being pricked or poked by a needle while sewing. The Old English word , the ancestor of thimble, is derived from Old English , the ancestor of the English word ''thumb''. History Pre-17th century As the purpose of a thimble is to prevent discomfort while sewing by providing a barrier between fingertips and the blunt end of a needle, it is likely that the earliest thimbles were created closely following the invention of sewing. According to the United Kingdom Detector Finds Database, thimbles dating to the 10th century have been found in England, and thimbles were in widespread use there by the 14th century. Although there are isolated examples of thimbles made of precious metals—Elizabeth I is said to have given one of her ladies-in-waiting a thimble set with precious stones—the vast majority of metal thimbles were made of brass. Medieval thimbles were either cast brass or made from hammered sheet. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kite Types
Kites are tethered flying objects which fly by using aerodynamic lift, requiring wind (or towing) for generation of airflow over the lifting surfaces. Various types of kites exist, depending on features such as material, shape, use, or operating skills required. Kites may fly in air, water, or other fluids such as gas and other liquid gaining lift through deflection of the supporting medium. Variations in design of tethering systems and lifting surfaces are regularly introduced, with lifting surfaces varying in stiffness from limp sheet material to fully solid material. Manufacture Kites may be built by the flier or by a dedicated kite manufacturer, which may be a member of the Kite Trade Association International (KTAI), which also includes kite retailers. Materials Kites have been made from the following materials: *Plastic – for example, a Styrofoam-only kite *Organic materials – such as plant leaves and grass *Paper *Textiles such as rip-stop nylon, nylon, or Dacron ...

James Forten
James Forten (September 2, 1766March 4, 1842) was an African-American abolitionist and wealthy businessman in Philadelphia, Pennsylvania. Born free in the city, he became a sailmaker after the American Revolutionary War. Following an apprenticeship, he became the foreman and bought the sail loft when his boss retired. Based on equipment he himself had developed, he established a highly profitable business. It was located on the busy waterfront of the Delaware River, in an area now called Penn's Landing. James Forten used his wealth and social standing to work for civil rights for African Americans in both the city and nationwide. Beginning in 1817, he opposed the colonization movements, particularly that of the American Colonization Society. He affirmed African Americans' claim to a stake in the United States of America. He persuaded William Lloyd Garrison to adopt an anti-colonization position and helped fund his newspaper '' The Liberator'' (1831–65), frequently publishing let ...

Sewing Machine
A sewing machine is a machine used to sew fabric and materials together with thread. Sewing machines were invented during the first Industrial Revolution to decrease the amount of manual sewing work performed in clothing companies. Since the invention of the first sewing machine, generally considered to have been the work of Englishman Thomas Saint in 1790, the sewing machine has greatly improved the efficiency and productivity of the clothing industry. Home sewing machines are designed for one person to sew individual items while using a single stitch type at a time. In a modern sewing machine, the process of stitching has been automated so that the fabric easily glides in and out of the machine without the inconvenience of needles, thimbles and other tools used in hand sewing. Early sewing machines were powered by either constantly turning a handle or with a foot-operated treadle mechanism. Electrically-powered machines were later introduced. Industrial sewing machines, by co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sewing Needle
A sewing needle, used for hand-sewing, is a long slender tool with a pointed tip at one end and a hole (or ''eye'') to hold the sewing thread. The earliest needles were made of bone or wood; modern needles are manufactured from high carbon steel wire and are nickel- or 18K gold-plated for corrosion resistance. High quality embroidery needles are plated with two-thirds platinum and one-third titanium alloy. Traditionally, needles have been kept in needle books or needlecases which have become objects of adornment. Sewing needles may also be kept in an étui, a small box that held needles and other items such as scissors, pencils and tweezers. Types of hand sewing needles Hand sewing needles come in a variety of types/classes designed according to their intended use and in a variety of sizes within each type. * Sharp needles: used for general hand sewing; built with a sharp point, a round eye, and are of medium length. Those with a double-eyes are able to carry two strands of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bench Hook
A bench hook is a workbench appliance used in woodworking to hold a workpiece in place while crosscutting with a hand saw. A bench hook is a simple method used to improve accuracy and safety. Construction Bench hooks are simple in construction and though they can be purchased, they are typically made by the woodworker from offcuts and scraps of timber or sheet goods (such as plywood). The most common type of bench hook is made from three pieces of wood joined together: * The ''bed'', being anywhere from wide and long depending on preference. The workpiece sits atop the bed, and the bed protects the workbench from the saw. * The first stop, also called the fence, is fixed across the top of the bed. Usually this stop doesn't span the full width of the bed, so that the end of the stop can be used as a guide while sawing. This way the saw cuts into the bench hook and not the workbench. * The other stop, or the ''hook'', being as long as the bed is wide, it is fixed into the und ...

Beeswax
Beeswax (''cera alba'') is a natural wax produced by honey bees of the genus ''Apis''. The wax is formed into scales by eight wax-producing glands in the abdominal segments of worker bees, which discard it in or at the hive. The hive workers collect and use it to form cells for honey storage and larval and pupal protection within the beehive. Chemically, beeswax consists mainly of esters of fatty acids and various long-chain alcohols. Beeswax has been used since prehistory as the first plastic, as a lubricant and waterproofing agent, in lost wax casting of metals and glass, as a polish for wood and leather, for making candles, as an ingredient in cosmetics and as an artistic medium in encaustic painting. Beeswax is edible, having similarly negligible toxicity to plant waxes, and is approved for food use in most countries and in the European Union under the E number E901. Production The beeswax is formed by worker bees, which secrete it from eight wax-producing mirror glan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
