Steam Bending
Steam bending is a woodworking technique where wood is exposed to steam to make it pliable. Heat and moisture from steam can soften wood fibres enough so they can be bent and stretched, and when cooled down they will hold their new shape. In modern times, steam bending is usually done with a steam box to make it bend around a former. The moulding process is typically done by clamping wooden strips to a positive form, with the strips of wood often reinforced on the outside with a metal band to prevent blowout. The method has been used in the manufacturing of a diverse range of products, including wooden boat building where it is used in the shaping of hull's ribs and lap boards, the production of traditional wooden lacrosse sticks, musical instruments such as the violin, the manufacture of wooden furniture such as the Windsor chair and much of Michael Thonet's and Alvar Aalto's work. Steam bending is a traditional process steeped in history. It was once a vital practice, paramoun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steambox
A steam box is a long, sealed container used to steam wooden planks for the purpose of making them pliable. Once steamed and then fastened or clamped into the desired position and left to dry, the wood will hold the new shape. Steam boxes allow for much more efficient use of wood. Instead of cutting the desired shape away from a large and more expensive piece of wood and leaving much scrap to be discarded, steam boxes allow for a smaller piece to be bent in the general shape and leaving much less scrap. Steam boxes also allow the wood to bend beyond its dry breaking point, which is useful in making extreme curves with the wood. In many cases, the bent piece is stronger than an identical piece cut from larger stock. Steam bending wood allows the wood grain to follow the bend, leaving it strong where a piece cut from larger stock would snap across crosscut grains or laminated joints. The largest steam boxes are used in boat building to bend the large planks for the frame and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Softwoods
Scots Pine, a typical and well-known softwood Softwood is wood from gymnosperm trees such as conifers. The term is opposed to hardwood, which is the wood from angiosperm trees. The main differences between hardwoods and softwoods is that the structure of hardwoods lack resin canals, whereas softwoods lack pores (though not all softwoods have resin canals). Characteristics Softwood is wood from gymnosperm trees such as pines and spruces. Softwoods are not necessarily softer than hardwoods. In both groups there is an enormous variation in actual wood hardness, the range of density in hardwoods completely including that of softwoods. Some hardwoods (e.g. balsa) are softer than most softwoods, while the hardest hardwoods are much harder than any softwood. The woods of longleaf pine, Douglas fir, and yew are much harder in the mechanical sense than several hardwoods. Softwoods are generally most used by the construction industry and are also used to produce paper pulp, and card ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haida People
Haida (, hai, X̱aayda, , , ) are an indigenous group who have traditionally occupied , an archipelago just off the coast of British Columbia, Canada, for at least 12,500 years. The Haida are known for their craftsmanship, trading skills, and seamanship. They are thought to have frequently carried out raids and to have practised slavery. The Haida have been compared to the Vikings by Diamond Jenness, an early anthropologist at the Canadian Museum of Civilization. In Haida Gwaii, the Haida government consists of a matrix of national and regional hereditary, legislative, and executive bodies including the Hereditary Chiefs Council, the Council of the Haida Nation (CHN), Old Massett Village Council, Skidegate Band Council, and the Secretariat of the Haida Nation. The Kaigani Haida live north of the Canadian and US border which cuts through Dixon Entrance south of Prince of Wales Island ( tli, Taan) in Southeast Alaska, United States; Haida from K'iis Gwaii in the Duu Guusd regi ...

Indigenous Peoples Of The Americas
The Indigenous peoples of the Americas are the inhabitants of the Americas before the arrival of the European settlers in the 15th century, and the ethnic groups who now identify themselves with those peoples. Many Indigenous peoples of the Americas were traditionally hunter-gatherers and many, especially in the Amazon basin, still are, but many groups practiced aquaculture and agriculture. While some societies depended heavily on agriculture, others practiced a mix of farming, hunting, and gathering. In some regions, the Indigenous peoples created monumental architecture, large-scale organized cities, city-states, chiefdoms, states, kingdoms, republics, confederacies, and empires. Some had varying degrees of knowledge of engineering, architecture, mathematics, astronomy, writing, physics, medicine, planting and irrigation, geology, mining, metallurgy, sculpture, and gold smithing. Many parts of the Americas are still populated by Indigenous peoples; some countries have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
