[Hallicrafters] SX-111 RF Alignment

[Rich Oliver]

Actually there is one more way to get the upper hand in this situation. 
  Take an old Allen Wrench you don't like very much and put a dab of 
epoxy on the end.  Stick it in the broken core and let it harden.  You 
then have a chance of removing the broken core in one piece and the 
problem is reduced to dressing the inside of the sleeve and locating a 
replacement core.

Good Luck!
