[TowerTalk] Position Pot

[Dave Sublette]

One more question for the learned crew here.  I got good advice from my
last inquiry about the pulley -- not going to do it.  Going to rig a single
pulley and a pulley on the tower leg at ground level and use the lawn
tractor as a mule to do the lifting.

Now onward:  For several years I have used Prosytel rotators with both the
ten turn, 10K pot and the 3 turn, 500 ohm pot.  The three turn is better.
But, with either method, the pots seem to go bad after two to four years.
Is there anything I can treat the pot with to lengthen its life span?  I'm
thinking things like fill the cavity under the gearbox with silicons grease
--- or some other scheme.

What say ye?
