[Eliot Ness]

Mike, one of my instructors showed us a device he used back in his radio/tv repair days.  It was called a goesinta (goes-in ta) (sp?) that threaded onto the threaded part of the shaft and when cleaner was sprayed in the other end it (in theory) forced it between the shaft and threads into the pot.  I didn't bother looking for one until years later and I have never found anything like it or even a reference to it.  I'm probably spelling it wrong, but at times that little gadget could come in handy.
