<html> What an important lesson... to check the hinge pins even if the lid is _up_.   Yes, if I have anything to contribute to this list , it is to echo this imperative:   ALWAYS check the hinge pins on a grand.   There is a grand in a local hotel with a PianoDisc which I tune regularly.  The bass end is against the wall.  The last time I tuned it, I (once again) craned my neck to check the hinge pins.  Yes, I was wondering: "why am I doing this... am I compulsive or what?"   Surprise!  One of the pins was missing.  How did it happen?  No one at the hotel knows.  Happened to have one in my kit that actually fit.
