[Drake] R4B "feedthrough" follow-up

[Bob Camp]

Hi

It's pretty amazing what you can find in the auto parts section of your 
local discount store these days. There are also a number of places on 
the net that will sell you the sort of stuff that is to exotic for the 
local store.

That said you need to be a little careful about what you use and the 
combinations of stuff you use. In some cases combinations of lubricants 
and cleaners can form something that resembles bubble gum. What ever 
you use, check it out first.

One thing that some have suggested in the past are silicon based 
greases. The advantage seems to be that they do not cake up as fast as 
the good old lithium loaded stuff. I certainly used an awful lot of 
Lubraplate back in the good old days. I have switched over to the 
silicon based stuff ...

	Take Care!
