[TenTec] How to Lubricate rotary inductors

That is why I used the term "Rotary Inductors" instead of "Roller 
Inductors." In the case of variable inductors, which use a little wheel 
which rolls on the inductor wire as the moving contact, I agree that it 
would be better not to put any lubricant on the incuctor wire or the 
outside of the wheel. Still I think the shaft which goes through the 
axis of the wheel ought to have some kind of lubrication.

Also there are variable inductors which use a sliding contact, instead 
of a rolling contact, such as the Johnson 226 series. I think that these 
should have some lube too.
