Philco 50 (Nathan's)
#30

The other thing I tackled tonight was the broken trimmer on the tuning capacitor.

First I took the tuning capacitor off and then disassembled it:

Then I took a closer look at how that trimmer screw is attached. It is in fact soldered on:

The tuning capacitor body makes a pretty good heatsink so I couldn't get the solder to melt with my iron. A butane torch took care of that though.  Icon_twisted

I got the remainder of the original bolt off - but it's a finer thread than the normal #4-40 ones I have around. Then I remembered that I have a parts 90 chassis - and it uses a very similar tuning capacitor design - it's just the big boy version.

I did the same trick with the butane torch and voila:

Since there was some rust on it and I had the tuning capacitor from the 50 disassembled I decided to throw the smaller parts into Evaporust overnight:

With the chassis empty it was also a good opportunity to take care of the rust spots there (as best I can) with naval jelly.

I've found the result with naval jelly is rarely very pleasing but at least the rust is removed and I can seal it with Boeshield.
