CAIG Laboratories makes a series of contact cleaning solutions and lubricants that are non-conductive but work quickly to enhance conduction through switch and connector contacts. I see no reason why they wouldn't work on a roller inductor without the risk of shorting turns. I've used them for years on some flakey Jones plugs and jacks.

Perhaps try petroleum jelly?  Thids is sold under the trade name "Vaseline" 
here in the UK. It's commonly used on car battery terminals as it's (a) conductive (at 
DC, I don't know about RF) (b) corrosion prevention and (c) a lubricant

I have a Nye-Viking tuner with their home made roller inductor.   The roller
has seized up on the shaft that guides it along the inductor.   They used
some sort of conductive grease on the shaft and a few other places on the
inductor assembly to improve contact.   Does anyone have a source for a
conductive grease I can use on the roller once I get it all apart and freed
up?


Hi Ralph,

Once you get that puppy free & loose of its moorings, lube any & all contact 
surfaces in the future with ordinary CASTOR OIL...

That's what I do here with my THREE roller inductors that I employ in two HB 
transmatches, & a HB linear amplifier. Don't go overboard with the stuff---use 
just enough to coat the surfaces smoothly, preferably after a complete pass, or to, 
of the mechanism after you've oiled it.

The maintenance & tooling department at GM in Oshawa used to do the castor oil trick on 
ALL of their electro-mechanical devices back in the day---and it works, too, but you'll 
probably have to re-visit the device after a couple of years, or so, to "freshen" 
it up.
