It may also be possible that at some point the glides were moved down,
raising the action a small amount.

Do thirty year old Bosies have glide bolts?  I know our forty year old ones
don't.

Hello everyone,
I am not a CAUT, but follow your list for helpful ideas.
Recently I encountered a Bosendorfer grand of about 30-year vintage and
noticed a strange hard click when a couple of the bass notes were played.
Upon investigation, it turned out that the shanks were striking the
underside of the pin block!  Others seem very close to striking as well.  My
feeling is that this piano always had close tolerances and that with hammer
wear the already small gap was closed.  It may also be possible that at some
point the glides were moved down, raising the action a small amount.
So far, short of hammer replacement, I have two ideas for a fix.  I could
shave the pinblock corner if the plate flange allows it, or I could see if
moving the action away from the player a fraction in the bass would provide
the necessary clearance.
Has anyone encountered this situation before, and what would you do about
it?

Thanks,
Todd Loomis
