A bow maker is a person who builds, repairs, and restores antique or modern bows for bowed string instruments. These include violins, violas, cellos, double basses, viola d'amore, viola da gamba, etc.
The French word for bowmaker (bow maker) is archetier, meaning one who makes bows of the string family of instruments such as violin, viola, cello and double bass.[1] The root of the word comes from archet—pronounced [aʁʃɛ]—the bow.
A bow maker typically uses between 150 and 200 hairs from the tail of a horse for a violin bow. Bows for other members of the violin family typically have a wider ribbon, using more hairs. White hair generally produces a smoother sound and black hair (used mainly for double bass bows) is coarser, producing a rougher sound. Lower quality (inexpensive) bows often use nylon or synthetic hair. Rosin, a hard, sticky substance made from resin (sometimes mixed with wax), is regularly applied to the bow hair to increase friction. In making the stick of a bow, the initial part of the woodworking is done on a straight stick. According to James McKean, "the bow maker graduates the stick in precise gradations so that it is evenly flexible throughout."[2] These gradations were calculated by François Tourte, discussed below. In order to shape the curve or "camber" of the bow stick, the maker carefully heats the stick over a source of heat (such as an alcohol flame or a heat gun) a few inches at a time, bending the heated stick gradually to the proper shape. A metal or wooden template is often used to get the exact model's curve and shape while heating.
