[Central-Electronics] 100V VFO help

[K6JEK]

Thanks to Nick Tusa's excellent instructions,  the VFO is out and 
sitting on the workbench.  But it is presenting challenges I wasn't 
expecting: foam, grease, ball bearings, caps & resistors.

The slug is badly misaligned with the coil form. It is almost 
immobilized.  I intend to follow Nicks instructions to re-align it.  
But when I removed the back cover to have a look I discovered a mess. 
The foam that lines the inside cover has disintegrated filling the 
inside with a grainy powder.  Does anyone have a suggestion for 
replacement material for this foam?

Today I hope to disassemble the actuator, clean out the dried grease, 
re-pack, and re-assemble.  I plan to use a mix of Radio Shack Gel Lube 
and synthetic oil.  Bill, N6PY, believes this Radio Shack lube is high 
temp Teflon grease.  Can anyone confirm this or give me a different 
source for Teflon grease?

I would like to replace the bearing assemblies if I can instead of just 
cleaning them. Does anyone know a source for small bearing assemblies?

And how about the caps & resistors in the VFO itself? I didn't intend 
to go through the VFO electrically but there the parts are sticking out 
like a sore thumb.  Should I resist the temptation to check caps & 
resistors or are there a few that I should really go after?

OK, OK, I'll stop asking questions.

Thanks,

Jon, K6JEK
