I got the tuning assembly put back together again. I took the entire assembly apart, polished all the brass pieces, and then sprayed them with clear acrylic. The posts that these ride on received a thin film of grease and the bearings were cleaned with spray cleaner and then I added a drop or two of light machine oil. Here are the BEFORE pictures:

You may notice that the spring is not wound as tightly after I put everything back together again. I tried winding it as tight as it once was but it was difficult and the spring started to cross over itself when I rotated the tuning capacitor. I have read elsewhere that it only needs to be wound titght enough to cause the tuning cap to spring closed when released and that's what it currently does.
