[Boatanchors] frozen potentiometer

FWIW. One of the best penetrating oils is a 50/50 mixture of Automatic 
Transmission Fluid (ATF) and Acetone. This stuff is better than 
commericial penetrating oil - and it's a lot less expensive. I'd apply 
just a small drop on the knob end of that center shaft then let it set 
and do it's work. Like Jim Pruitt said the Acetone will carry the AFF 
into the frozen parts and evaporate, leaving the lubricating ATF.
