Anigre

Anigre is an African hardwood commonly used for plywood, interior furniture, cabinetry, and high-end millwork applications. It is frequently sliced and sold as veneer, although it is available in board form as well. In board form it is used for boat building, general carpentry, and other light construction uses.

Characteristics

It is considered a tropical hardwood with a clear, cylindrical bole to 80 feet (24 m). It can grow to heights of 180 feet (55 m) with typical trunk diameters ranging from 36 to 48 inches (910 to 1,220 mm). Anigre has a medium texture with closed pores similar to maple. Growth rings aren’t always well-defined, and the wood can be rather plain-looking; though certain figure is occasionally present, such as curly or mottled grain. The sapwood and the heartwood are not usually distinguishable. The heartwood is a light yellowish-brown, sometimes with a pinkish hue. Color tends to darken with age. The quarter figured veneer has become a popular choice for furniture, cabinetry, and decorative architectural applications. It is said to have a faint odor similar to Cedar. In its untreated form Anigre is susceptible to termite and fungi attacks and generally has low durability. Anigre is usually considered easy to work with hand and power tools, although depending on the origin of the wood it can have a high silica content which can dull wood working tools quickly.

Bronze wool

Bronze wool is a bundle of very fine bronze filaments, used in finishing and repair work to polish wood or metal objects. Bronze wool is similar to steel wool, but is used in its place to avoid some problems associated with broken filaments: steel rusts quickly, especially in a marine environment. Furthermore, steel is magnetic and can affect the operation of marine equipment, such as a compass. Steel can also discolor some materials, such as oak. This discoloration results from a reaction between the tannates in the oak and the iron in the steel, forming iron tannate, a black compound.

Bronze wool also has uses for filter elements, again when rusting would be a problem.

The main US retail supplier of bronze wool is Homax Group, under their Rhodes American brand.

Bronze wool has largely been replaced for cost reasons, by plastic mesh abrasives from makers such as Webrax and 3M Scotch-Brite. These use grains of aluminium oxide or silicon carbide, bonded to a non-woven web of nylon fibres. Like bronze wool, they avoid rust problems.

Chamfer

A chamfer is a transitional edge between two faces of an object. Sometimes defined as a form of bevel, it is often created at a 45° angle between two adjoining right-angled faces.

Chamfers are frequently used in machining, carpentry, furniture, concrete formwork, mirrors, printed circuit boards, and to facilitate assembly of many mechanical engineering designs.

Douglas fir

Pseudotsuga menziesii is an evergreen conifer species in the pine family, Pinaceae. It is native to western North America and is known as Douglas fir, Douglas-fir, Oregon pine, and Columbian pine. There are two varieties: coast Douglas-fir (P. menziesii var. menziesii), and Rocky Mountain Douglas-fir (P. menziesii var. glauca).

Framing (construction)

Framing, in construction, is the fitting together of pieces to give a structure support and shape. Framing materials are usually wood, engineered wood, or structural steel. The alternative to framed construction is generally called mass wall construction, where horizontal layers of stacked materials such as log building, masonry, rammed earth, adobe, etc. are used without framing.Building framing is divided into two broad categories, heavy-frame construction (heavy framing) if the vertical supports are few and heavy such as in timber framing, pole building framing, or steel framing; or light-frame construction (light-framing) if the supports are more numerous and smaller, such as balloon, platform, or light-steel framing. Light-frame construction using standardized dimensional lumber has become the dominant construction method in North America and Australia due to the economy of the method; use of minimal structural material allows builders to enclose a large area at minimal cost while achieving a wide variety of architectural styles.

Modern light-frame structures usually gain strength from rigid panels (plywood and other plywood-like composites such as oriented strand board (OSB) used to form all or part of wall sections), but until recently carpenters employed various forms of diagonal bracing to stabilize walls. Diagonal bracing remains a vital interior part of many roof systems, and in-wall wind braces are required by building codes in many municipalities or by individual state laws in the United States. Special framed shear walls are becoming more common to help buildings meet the requirements of earthquake engineering and wind engineering.

Heat bending of wood

Heat bending is the procedure of bending thin sheets of wood into different curves and shapes using moisture and a bending iron. By placing the sheet of wood into water, the moisture and heat from the bending iron will reform the structure of the wood, reorganizing the fibers of the wood to prevent the wood from springing back to its original state. This process is usually used for making sides or "ribs" for violins, guitars, mandolins and other projects, and also for woodworking such as shaker-style pantry boxes.

Juniper

Junipers are coniferous trees and shrubs in the genus Juniperus of the cypress family Cupressaceae. Depending on taxonomic viewpoint, between 50 and 67 species of junipers are widely distributed throughout the Northern Hemisphere, from the Arctic, south to tropical Africa, from Ziarat, Pakistan, east to eastern Tibet in the Old World, and in the mountains of Central America. The highest-known juniper forest occurs at an altitude of 16,000 ft (4,900 m) in southeastern Tibet and the northern Himalayas, creating one of the highest tree-lines on earth.

Ogive

An ogive ( OH-jyve) is the roundly tapered end of a two-dimensional or three-dimensional object. Ogive curves and surfaces are used in engineering, architecture and woodworking.

Paint stripper

Paint stripper, or paint remover, is a chemical product designed to remove paint, finishes, and coatings while also cleaning the underlying surface.

The product's material safety data sheet provides more safety information than its product labels.

Paint can also be removed using mechanical methods (scraping or sanding) or heat (hot air, radiant heat, or steam).

Lead-based paint is banned in the United States. Removing old lead-based paint can disperse lead and cause lead poisoning, leading several US workplace and environmental regulations address removal of old paint that could contain lead.

Pouteria altissima

Pouteria altissima is a species of plant in the family Sapotaceae, and a source of anigre hardwood. It is found in Burundi, Cameroon, Central African Republic, the Republic of the Congo, the Democratic Republic of the Congo, Ivory Coast, Ethiopia, Gabon, Ghana, Guinea, Kenya, Nigeria, Rwanda, Sierra Leone, Sudan, Tanzania, and Uganda. It is threatened by habitat loss.

Society of Wood Engravers

The Society of Wood Engravers was founded in 1920 by the artists Noel Rooke and Robert Gibbings, who were the driving force behind the society, and Edward Gordon Craig, E.M.O'R. Dickey, Eric Gill, Philip Hagreen, Sydney Lee, John Nash, Lucien Pissarro, and Gwen Raverat. The aim of the society has been to promote original white line wood engravings, designed and engraved by the artist, as opposed to the wood engravings of the nineteenth century, where skilled craftsmen engraved the design of the artist. The impetus behind this new philosophy was Rooke.

The Society went into abeyance during the 1960s, but was revived in 1984 by Hilary Paynter. It publishes a bulletin called Multiples.

The Annual Exhibition of the Society tours the UK. In November and December 2017, the 80th Annual Exhibition was held in Petworth, West Sussex.

Notable former Members include:

David Jones
