[TowerTalk] Lubricating air variable capacitors

[zl1aih@ihug.co.nz]

The manual for the RCA AT3 transmitter (1943) recommended a 
solution of anhydrous lanolin dissolved in white spirit to lubricate the 
roller carriage on roller inductors - apply sparingly.

I've had excellent results using the automatic dishwasher when 
refurbishing roller coils and air variables - the abrasive powder brings 
the ceramic back to 'as new' condition.
Of course, all the bearings must be lubed afterwards.
