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.
