Rigging
Steel Cable
"The design to go for, in a sheave carrying wire cable, is 40X
the cable diameter. This is what we used to use for all shipboard
sheaves where the cable had to have a long working life. Anything
less than this figure and you reduce the working life of the cable.
Going *much* less reduces the life really fast. So, 6mm should
ideally have 240mm sheaves." --PDW
Also galvanized steel cable takes flexing better than stainless
steel cable.
