Green Woodworking
Green woodworking (also written greenwoodworking) is a form of woodworking that uses unseasoned or "green" timber. The term "unseasoned" refers to wood that has been freshly felled or preserved by storing it in a water-filled trough or pond to maintain its naturally high moisture content. This wood is much softer than seasoned timber and is therefore much easier to shape with hand tools. As moisture leaves the unseasoned wood, shrinkage occurs. This can be used as an advantage, as this shrinkage can help ensure tight joints. To enhance the effect of the shrinkage, a half of a joint may be forcibly over-dried in a simple kiln while its encapsulating component is left green. The components tighten against each other as the parts exchange moisture and approach equilibrium with the surrounding environment. The swelling of the dry tenon inside the shrinking “green” mortise makes for an incredibly tight and permanent joint despite a lack of adhesives. Bodging is a traditional green wo ...

Woodworking
Woodworking is the skill of making items from wood, and includes cabinetry, furniture making, wood carving, joinery, carpentry, and woodturning. History Along with stone, clay and animal parts, wood was one of the first materials worked by early humans. Microwear analysis of the Mousterian stone tools used by the Neanderthals show that many were used to work wood. The development of civilization was closely tied to the development of increasingly greater degrees of skill in working these materials. Among the earlliest finds of woodworking are shaped sticks displaying notches from Kalambo Falls in southen Africa, dating to around 476,000 years ago.

Bodging
Bodging (full name chair-bodgering) is a traditional woodturning craft, using Green woodworking, green (unseasoned) wood to make chair legs and other cylindrical parts of chairs. The work was done close to where a tree was felled. The itinerant craftsman who made the chair legs was known as a bodger or chair-bodger. According to Collins Dictionary, the use of the term bodger in reference to green woodworking appeared between 1799 and 1827 and, to a much lesser extent, from 1877 to 1886 and from 1939 to present. History The term was once common around the furniture-making town of High Wycombe in Buckinghamshire, England. Traditionally, bodgers were highly skilled wood-turners, who worked in the beech woods of the Chiltern Hills. The term and trade also spread to Ireland and Scotland. Chairs were made and parts turned in all parts of the UK before the semi industrialised production of High Wycombe. As well recorded in Cotton the English Regional Chair. Bodgers also sold their was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bentwood
Bentwood objects are made by wetting wood (either by soaking or by steaming), then bending it and letting it harden into curved shapes and patterns. Furniture-makers often use this method in the production of rocking chairs, cafe chairs, and other light furniture. The iconic No. 14 chair (also known as the "Vienna chair"), developed in the 1850s in the Austrian Empire by Thonet, is a well-known design based on the technique. The process is in widespread use for making casual and informal furniture of all types, particularly seating and table forms. It is also a popular technique in the worldwide production of furniture with frames made of heavy cane, which is commonly imported into European and Western shops. Bentwood boxes are a traditional item made by the First Nations people of the North American west coast including the Haida, Gitxsan, Tlingit, Tsimshian, Sugpiaq, Unangax, Yup'ik, Inupiaq and Coast Salish. These boxes are generally made out of one piece of wood that i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engineered Wood
Engineered wood, also called mass timber, composite wood, man-made wood, or manufactured board, includes a range of derivative wood products which are manufactured by binding or fixing the strands, particles, fibres, veneers, or boards of wood, together with adhesives, or other methods of fixation to form composite material. The panels vary in size but can range upwards of and in the case of cross-laminated timber (CLT) can be of any thickness from a few inches to or more. These products are engineered to precise design specifications, which are tested to meet national or international standards and provide uniformity and predictability in their structural performance. Engineered wood products are used in a variety of applications, from home construction to commercial buildings to industrial products.

Green Building And Wood
Green building is a technique that aims to create structures that are environmentally responsible and resource-efficient throughout their lifecycle – including siting, design, construction, operation, maintenance, renovation, and demolition. A 2009 report by the U.S. General Services Administration evaluated 12 sustainably designed GSA buildings and found they cost less to operate. Wood products from responsible sources are a good choice for most green building projects – both new construction and renovations. Wood grows naturally using energy from the sun and is renewable, sustainable, and recyclable. It is an effective insulator and uses far less energy to produce than concrete or steel. Wood can also mitigate climate change because wood products continue to store carbon absorbed by the tree during its growing cycle, and because substituting wood for fossil fuel-intensive materials such as steel and concrete result in ‘avoided’ greenhouse gas emissions.

Jennie Alexander
Jennie Alexander (December 8, 1930 – July 12, 2018) was an American author. Background Jennie Alexander spent her early childhood in Baltimore, Maryland learning to play the piano and later became a Jazz musician. She was introduced to woodworking at the Baltimore polytechnic institute High School and would later go on to open up her own home shop in 1960. Her mother grew up in Quincy, Massachusetts, and was part of the educational sloyd system. Because of this Jennie was always encouraged to explore woodworking and learning through doing. Her father was a lawyer, and Jennie also attended law school at the university of Maryland, becoming a divorce lawyer. She embraced greenwoodworking as an avocation. She both practiced greenwoodworking, and studied the history of greenwoodworking by examining furniture at museums, private collections, auction houses, etc. Born as John David Alexander Jr., Alexander was a trans woman who transitioned in 2007, at the age of 77. Alexander' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Timber Recycling
Timber recycling or wood recycling is the process of turning waste timber into usable products. Recycling timber is a practice that was popularized in the early 1990s as issues such as deforestation and climate change prompted both timber suppliers and consumers to turn to a more sustainable timber source. Recycling timber is the environmentally friendliest form of timber production and is very common in countries such as Australia and New Zealand where supplies of old wooden structures are plentiful. Timber can be chipped down into wood chips which can be used to heat homes or generate electricity. Benefits Recycling timber has become popular due to its image as an environmentally friendly product. Common belief among consumers is that by purchasing recycled wood, the demand for "green timber" will fall and ultimately benefit the environment. Greenpeace also view recycled timber as an environmentally friendly product, citing it as the most preferable timber source on their w ...
