[Heath] AR-3 Tuning Cap

[G3OOU at aol.com]

Hi Everyone
 
Any thin solvent or lubricant should eventually wick into the gap between  
the two concentric shafts but the more volatile the liquid the quicker it 
will  evaporate so a sealed container might be required. 
 
How about removing the tuning capacitor from the receiver and putting it  
shaft downwards into a suitable sized clean jam jar with a small amount of  
paraffin in the bottom and leaving it to soak for a while with a lid on the 
jar? 
 
A more volatile alternative to paraffin would be white spirit  (household 
paint thinner) which I use as a degreasing agent when cleaning panels  prior 
to priming and painting.
