[Drake] Drake R4B Audio Pot

[Ron Hunsicker]

On a very variable day near Reading, Pennsylvania:


Recapping (sic) a previous post about the audio gain control on a Drake 
R4B, the brass shaft became disconnected from the body of the audio pot 
(3K) of my R4B.

Ron Wagner's suggestion to glue it together seemed the best idea, but to do 
that I felt that I had to disassemble the pot.  Opening  the pot revealed 
the real problem.  The moving brass contact is lace-like and is attached to 
a plastic carrier.  The plastic carrier is broken and some small pieces are 
missing (Perhaps the radio was dropped on its head at some point and the 
audio gain shaft took the brunt.).

I'm considering gluing the plastic carrier together and then gluing the 
moving brass contact to the plastic.

Any thoughts?

Also, there is lubricant on the plastic parts that I'd like to remove 
before I try gluing it.  Any suggestions for a "safe" product that will not 
damage the plastic?  Or, simply wipe the plastic quickly with a solvent and 
rinse with water?

Unless, of course, one of you has an audio pot from a parts radio that you 
might want to sell....


Thanks for any ideas,
