[TowerTalk] old rotor contacts repair question

[David Huff]

I have just acquired an old CDE / Ham II rotor and now I am reconditioning it.  I have 2 questions.


  1.  The previous owner used steel screws or washers on the rotor electrical screw terminals, which means I need to remove the rust.  My plan is to replace with brass or stainless screws and washers.  It rotates, and the meter needle moves, but is jumpy, probably because of the rusty terminals.  What do you recommend for a good cleaner to get the electrical pads clean again.
  2.  Is there something I can cover the screw terminals with to prevent the water from getting in and creating problems in the future?

Thanks,
David
