[pianotech] Kimball Console Action Holddown Screws

[Kerry]

Not to throw gasoline on this smoldering thread, but I seem to recall
someone in the PTJ recommending caution in what lubrication to use on tight
screws because some types can cause corrosion. I've used VJ and it worked
fine, but I don't recall if I ever went back later and checked it to see if
it was ok years later. Anybody know more about this?

I don't think that I've ever had to pull one of these actions 
twice. I lube the original screws pretty thoroughly, drive 
them back in by HAND (doing no more damage spinning a bit in 
the head), and presume that the next guy that pulls the action 
in another twenty years or so will benefit from the lubricated 
screws. What I won't do is carry replacements for the once 
every five year time this comes up, nor make a $75 trip to the 
hardware store, killing an hour, to replace them with 
something no better functionally than was there. Just make it 
possible to get the damned things in and out without further 
trashing them (if you can get them out in the first place), 
and you've rendered appropriate service to the customer.
