Almost any fiber may be used in emergency. Natural fibers would be very unusual on a modern recurve bow or compound bow, but are still effective and still used on traditional wooden or composite bows. Sinew and hide strings may be seriously affected by water. [4] The author of Arab Archery suggests the hide of a young, emaciated camel. [5]
Compound bow strings and cables are normally made of high-modulus polyethylene and are designed to have great tensile strength and minimal stretchability, so that the bow transfers its energy to the arrow as efficiently and durably as possible. In earlier models of compound bows, the cables were often made of plastic-coated steel.
This limb stiffness makes the compound bow more energy-efficient than other bows, in conjunction with the pulley/cams. The typical compound bow has its string applied to pulleys (cams), and one or both of the pulleys have one or more cables attached to the opposite limb. When the string is drawn back, the string causes the pulleys to turn.
Large string bridges are characteristic of Manchu (Qing dynasty, 1644–1911) bows and late Mongolian bows, while small string bridges are characteristic of Korean, Crimean Tatar, and some Ming dynasty (1368–1644) bows. [36] [37] [38] String bridges are not present in artwork in the time of Genghis Khan or before.
Estimates for the draw of these bows varies considerably. Before the recovery of the Mary Rose, Count M. Mildmay Stayner, Recorder of the British Long Bow Society, estimated the bows of the Medieval period drew 90–110 pounds-force (400–490 newtons), maximum, and W. F. Paterson, Chairman of the Society of Archer-Antiquaries, believed the weapon had a supreme draw weight of only 80–90 lb f ...
let-off (measure) – The difference between a compound bow's holding weight and draw weight. Expressed as a percentage of the draw weight; for example, a bow with a draw weight of 70 lb and holding weight of 14 lb would have 80% let-off. limb-driven rest (equipment) – A drop-away rest that is mechanically linked to one of a compound bow's limbs.
