Hello TowerTalkers,

 I was doing some tower work recently and was having trouble keeping the rope running as free as I would like through the pulley head. I am using a gin pole based on the GP-81 kit from W9IIX (http://www.w9iix.com/ii00008.htm), with some modifications. I replaced the flat-faced pulley sheave with a rounded-groove sheave having a bronze bushing.

I found that the rope ran significantly more freely if I turned the pulley opening toward the tower during section attachment/detachment, and toward the landing zone on the ground during the lifts. I was turning the gin pole mast manually in the clamp about 180 degrees each time. I'd like to have this automatic without having to loosen the mast clamp.

 Have any of you converted your gin poles with a swivel arrangement? How did you accomplish it mechanically?

Thanks for your suggestions,
