[pianotech] grand dip regulation on the bench

[David Nereson]

    There was a recent article, probably in the Journal, but 
maybe it was a tip on this list, about doing something in the 
shop to a grand action on the bench to create the same key dip 
it will have when put back in the piano.  It was fairly recently 
(a few months), but I can't find it in my Journals.  Anybody 
know what that "trick" is?  (Usually when brought to the shop 
and put on a bench, the key height & dip, for some reason, are 
different than when in the piano).
