[Milsurplus] BC-221-AK Suggestions wanted.

[Revcom]

On "stuck" set screws, we have found some, being treated with the -blue or green- stuff that sets them up like loctite, can be 
loosened up by applying some Service Solvent, made by GC Electronics.  Available from most electronics parts houses.  We
get ours from MCM.  GC # 10-318.   Be careful it is nasty stuff, plenty of ventilation required.  Has acetone and toluene in it, 
and is a restricted product in some places.  Works wonders for me.  Let it soak a little while and screws thread right out.
Softens up that green cement on BC-375 stuff real good.

  Fellow Listers -  
  An Up date - Click my heals!
  After hitting the Master Oscillator Coils temperature compensating Gizmos with De-Oxit and Liquid-Wrench and gently pushing at the base of the pinion bearing the Low Band came into the reach of the Corrector adjustment range!  Seems there was a bit of corrosion in the bearing joint was not allowing the Gizmos to do their job.  I'm not going to change the resistors as of yet until I can get the knobs loose.  To bad the old owner had penciled in new settings for the cal points.  I will have to gently erase those out of the Calibration book.

  The set screws are  Allen Hex  head.
  Suggestions so far:
    1: Kroil works better than Liquid Wrench.
    2: Another good penetrating agent is PB-Blaster. 

  Is there a Miniature Air impact wrench?
  Thanks for your suggestions
  Hutch
