[Hallicrafters] Driver Tuning Coils

[David C. Hallam]

I have gotten the HT-37 back together and am now working on its alignment.
The cores in the driver tuning coils for the 20 meter band are very
resistant to turning.  Some place I seem to remember I read that a little
talcum powder was good to use to lubricate slug tuned coils.  No oil or
anything like petroleum products should be used.  Does anyone know about
talcum powder or know of anything that is good to use?
