It's a 1925 Chickering Grand beautifully rebuilt.  And it has tuning pin
bushings, so none of the tuning pins are touching the plate.  (It's
beginning to seem like I'm worrying about nothing).

  What kind of piano & are if there are no plate bushings are the pins
touching the plate?
  Yamaha pianos have very little block contacting the flange. Ask any one
who has replced one.

   I guess I didn=B9t explain myself too well in my previous post on pinblock
fitting.  The answers I received so far ignored the fact that the pinblock
to plate flange fit had gaps in it and implied that frequent tunings is the
only solution.  What I need to know is if there is a situation where the
pinblock to plate fit doesn=B9t matter.  This is contrary to all I=B9ve been
told and all I=B9ve read about over the years.  All replies will be
appreciated.

What=B9s the latest on whether or not a pinblock should butt against the plat=
e
flange?  I have a customer who has a rebuilt piano that won=B9t hold tune for
even a day and when I removed the action and checked the pinblock-to-plate
fit I found gaps throughout, some as much as 1/8 inch.  Two weeks after I
tuned it I found it over 20 cents flat and had to give it a pitch raise.  A
few weeks later it was overly flat again and in need of a pitch raise.  I
explained to the customer about the pinblock to plate flange fit but he sai=
d
that he was told by the rebuilder that such a thing was not important.  To
top it off he did some research and got conflicting comments.  Some said th=
e
piano is OK as is while others held to the conviction that the gaps in the
pinblock are the problem with his piano.  I need some backup in my
assessment, either pro or con.
