[TowerTalk] Pulleys

[Jon Pearl - W4ABC]

Hi Mike,

Heights Tower Systems makes them for their towers and supposedly can 
make them to order, if need be:

*"Pulleys* - -  We have pulley sheaves of stainless, aluminum and steel 
material, with and without bronze bushings; we also have aluminum Roller 
Spools. Diameters run between 1.75" and 4.5". Call factory for prices, 
including some special clear-outs. Here are a few examples.  If you need 
custom pulleys, please forward drawing or dimension specs for a 
quotation.  We specialize in aluminum with bronze inserts."

Odds and ends:

I had bought replacements from McMaster-Carr a bit over a year ago. They are steel and the bearing is fairly thin.. I had one used pulley in my junk box which has a much thicker bearing, not sure if it was an original.
