The making of natural ropes and cords.
Almost any natural fibrous material can be spun into good,
serviceable rope or cord. Many materials which have a
length of 30 to 60 cm or more can be plaited or braided.
Ropes of up to 5 and 10 cm diameter can be 'laid' by four
people, and breaking strains for bushmade rope of 5 cm diameter
range from 50 kg to as high as 1000 kg.
BREAKING STRENGTH is usually a three-lay rope of 3 cm diameter
as standard, the following list of breaking strains gives an
idea or guide to the general strengths of various bush materials.
For safety's sake always regard the lowest figure as the
actual breaking strain unless tests have shown otherwise.
Green grass 50-100 kg
Bark fibre 200 - 700 kg
Palm fibre 300 - 1000 kg
Sedges 900 - 1000 kg
Lianas (monkey vines) 250 - 300 kg
Lawyer vine (Calamus) 500 kg
(10 mm diameter, unskinned]
