Probably the best lead about pulleys is to talk to a person that uses
pulleys in everyday life. I had A pulley system designed and built by a
local aluminum and stainless steel fabricator that builds 60-100' steel and
aluminum boats for the fishing industry here in Fort Bragg, Calif. He had
a stock of pulleys of all sizes, all galvanized, all with bronze bearings
and all sealed against the weather. The highest pulley I have is at the
top of the mast. I've got 20' of gal. tubing for the main mast, a sleeve
and 20' of thick wall aluminum tubing with the pulley in a captured mount
at the top. This is where I mount the dipoles for 160 and 80
meters. They are pulled up with 3/8" rope. The guarantee I got with the
'custom' job was that he would climb the mast and replace the pulley if it
ever fails,, I'll go with that,,,
