[Milsurplus] Re: [Boatanchors] Removing beeswax from slug-tuned transform...

Frank,

I orginally started the thread, not John.  The requirement was to adjust IF 
transformers which had not apparently been adjusted since the radios were built 
in late '44 or early '45.  The elegent solution turned out to be a brief 
blast of superheated air applied at the top of the slug below the surface of the 
beeswax, which vaporised the beeswax and blew it out of the hole.  

Comments about cracked slugs were in reference to the consequences of 
attempting to remove the wax mechanically, or of attempting to adjust the slugs 
without removing any of the wax.  An unfortunately common situation when someone 
else has been into the radio.

The solvent comments were because I thought I remembered something from the 
50's used for the purpose.  But that apparently turns out not to be the case.

I think that should do it for the beeswax thread.  Thanks to all who 
responded.
