   From having faced this exact problem during the re-build of my R-388, 
the only tidbit I have to offer (in the midst of all this utterly terrific 
info and 'hints & kinks'!!) is that, to heat the KC dial hub, I used one 
of those Weller small hand-held heat guns (not the big 1500 watt jobs) and 
directed the hot air onto the hub and shaft using the short extension pipe 
that came with the gun - in five minutes of judicious heating, the locking 
compound loosened and the set-screw was free.

   For what it's worth - Howard Mills also provides replacement KC dials 
for these radios... he told me that sometimes cutting or melting the dial 
is inevitable.
