A Glossary is a list of terms and their definitions.
A
Abrasive - Abrasives can be simply defined as materials that are used to shape, smooth, sculpt, or finish an object by rubbing, resulting in wear to the surface. When the abrasive is put on a backing such as paper, cloth, or film, it is usually referred to as sandpaper, emery paper, or sanding cloth.
Abrasive Grade – Specifies the grit size of an abrasive product. There is a relationship to the size of the abrasive grains and the grade number, the higher the grade number, the smaller the grain size.
Abrasive Classification Systems - Two primary standards exist for classifying the grit size of abrasives. In the U.S., the CAMI (Coated Abrasives Manufacturing Institute) standard is used; Europe uses the FEPA (Federation of European Producers of Abrasives) standard. Japan uses the JIS (Japanese Industrial Standard), which is equivalent to the FEPA standard. FEPA graded abrasives can be easily distinguished by the letter "P" in front of the grit number, such as P240. There are sizing differences between the CAMI and FEPA standards, so the two standards are not universal.
Acetone - Acetone (Also known as: 2-Propanone or Dimethyl Ketone) is a powerful, fast acting Ketone solvent for epoxies, polyester, vinyl, lacquer, contact cement, plastics and adhesives. Acetone is a clear, colourless liquid with a sharp penetrating, non-residual odour at ambient temperatures. The primary use in woodturning is as a solvent for CA glue.
Air-Drying – A method of drying green timber such as turning squares, blanks, or roughouts whereby the wood is allowed to dry, or season exposed to natural atmospheric conditions in the open air. The endgrain and high figured areas are typically coated with a cold wax emulsion (endgrain sealer) to reduce any checking.In areas with very low humidity, the entire blank, or roughout is frequently coated with a cold wax emulsion. Air drying green wood preserves subtle colours and delicate highlights in the timber that are usually destroyed by kiln drying.
Aluminum Oxide – A popular manufactured abrasive, featuring very hard wedge shaped grains that lack a clearly defined crystal structure. Aluminum Oxide was introduced in 1900 and is manufactured using High Temperatures from Bauxite. Aluminum Oxide abrasives include those made from Brown, White, Pink and Ruby Aluminum Oxide grains.
Annual Rings – Concentric growth rings added yearly to growing trees that are visible on the end grain portions of cut logs.
ANSI - American National Standards Institute - Organization maintaining standards used by many different industries.
Arbor – (a) A Morse taper fitting that is used for mounting various fixings like drive spurs, buffing wheels, revolving ball bearing centres, Jacob's chucks and other tools in the lathe headstock, or tail-stock. (b) A shaft used to mount sanding mandrels, small grinding wheels, cones, sanding stars, flap wheels and similar items for use in power tools.
ASTM - American Society for Testing and Materials – Organization for technical standards
