Sailmaker
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, maintaining and repairing 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 (CFD), th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lowell North
Lowell Orton North (December 2, 1929 – June 2, 2019) was an American competitive sailor and Olympic gold medalist.

Biography North was born in Springfield, Missouri on December 2, 1929. He was the son of Williard North, a geophysicist for oil companies, and Juanita Williams North, a homemaker. When Lowell was young the family moved to Southern California, where he learned to sail in Newport Beach and later in San Diego. He got his start as a sailmaker at the age of 14, when he and his father raced Star class boats and regularly lost. He recut the sail and improved their record. In 1945, at age 15, he crewed for Malin Burnham in the Star World Championship, which they won. North later said, "It wasn’t me Malin wanted. It was my mainsail." During the next 30 years he won another four Star Worlds. He studied at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James Forten
James Forten (September 2, 1766March 4, 1842) was an American Abolitionism in the United States, abolitionist and businessman in Philadelphia, Pennsylvania. A free-born African American, 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-American Colonization Society, colonization position and helped fund his newspaper ...

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] |

Sail Loft
A loft is a building's upper storey or elevated area in a room directly under the roof (American usage), or just an attic: a storage space under the roof usually accessed by a ladder (primarily British usage). A loft apartment refers to large adaptable open space, often converted for residential use (a converted loft) from some other use, often light industrial. Loft and attic In US usage, a loft is an upper room or storey in a building, mainly in a barn, directly under the roof, used for storage (as in most private houses). In this sense it is roughly synonymous with attic, the major difference being that an attic typically constitutes an entire floor of the building, while a loft covers only a few rooms, leaving one or more sides open to the lower floor. In British usage, lofts are usually just a roof space accessed via a hatch and loft ladder, while attics tend to be rooms immediately under the roof accessed via a staircase. Lofts may have a specific purpose, e.g. an org ... [...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. 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 Wing c ...

Sewing Machine
Diagram of a modern sewing machine Animation of a modern sewing machine as it stitches 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. Early sewing machines were powered by either constantly turning a flywheel handle or with a foot-operated treadle mechanism. Electrically-powered machines were later introduced. Industria ...

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 gold, 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. With each type also varying in size. * 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 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bench Hook
A bench hook is a Workbench (woodworking), workbench appliance used in woodworking to hold a workpiece in place while Cross-cutting, 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 (woodworking), 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'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
