Drop Testing a Piano
By John A. Tuttle

[ Ref. 050428 MMDigest, Duo-Art Cross Valves Modification

Hi All,  I had to laugh when I read the postings about dropping or
hitting a piano in order to get it to work correctly.  What a hoot!

What makes this so funny is my clear recollection of what was done in
the Calibration Laboratory at Lakehurst Naval Air Station when a piece
of electronic equipment was a real pain to repair.

Every so often a piece would come into the lab that seemed to defy
being fixed.  We'd fix one problem. only to find another, and another,
etc.  After a week or so on the bench, and having replaced so many parts
that the internal components were all basically brand new, the piece
would 'mysteriously' fall off the bench.  It was then red-tagged,
marked "Failed Drop-Check", and sent to salvage.

Since leaving the military some thirty years ago I've only heard the
term 'drop-check' a few times, but in every case it was said in jest.
The simple fact is, if you have to resort to dropping or hitting
something to get it to work, face reality: there's a problem!  Don't
abuse the item -- fix it!
