[ARC5] Tuning Capacitor Removal - Help, please!

To add to Mr. Gordon's excellent guidance:

Close the cap fully before starting.

Mike Hanz can give the best guidance on
getting the metal straight.  IMHO, I'd remove
the cap completely.  Not too tough to do.
Just disconnect all the wires, and the little 
cap that connects to the antenna post,
remove the screws and lift it out.

While you have it out, look for corrosion or
oxidation at the stator connection strips
which are pressure-fit on the end of 
the stator elements.  If it looks "hinky,"
you'll need to clean and solder across 
the junction, being careful not to over-heat
and melt the stator mounts.  This is getting
to be a big problem with these, as well
as the transmitter caps.  I've fixed a couple 
by using 6 volts worth of batteries and 
some soft copper wire to "spot weld" 
across the junction.  Worked well.

Be careful not to lose the small pin that aligns
the dial with the capacitor mechanicals.

If the antenna post nut is hard to get off, don't force it.
It will strip.  Soften the glyptol with some paint remover.
Clean it well before reassembly.

Let me know if the antenna post or insulators are broken;
I have replacements.
