[TowerTalk] Pulley at the top corner of an inverted L

[Grant Saviers]

For "non-conductive marine" you might look for plastic sheaves in carbon 
fiber flanges, but I don't think that the little bump of a conductive 
block would make much difference if attached to an insulated hoist line.

What will make a difference to the wire fatigue life is a larger 
diameter sheave, so I would recommend something closer to 2" diameter. 
Any sheave will be better than an insulator.

If I insulate the pulley from the haul-up rope, is it a good/bad/indifferent idea to string the inverted L wire (14 copper, stranded) through the pulley rather than just using an insulator to make the bend.  It strikes me that having the bend move, however slightly, on the wire is likely to be less destructive than just having a sharp bend moving through an insulator end..
