<DIV><FONT size=2> I wasn't in on the original =
question
here. My reply may not fit the original question so I'll just
comment. </FONT></DIV>
<DIV><FONT size=2> I've only come across one cracked =
plate so
far. Kimball console. It was a half step flat. I =
raised the
pitch and it went back to half step flat. I suspected cracked =
plate but
couldn't find it. I called Roger W. at Kimball and he told =
me where
to look. Sure enough, the crack was there, but it was discreet and =
hard to
see. I had to pull the action. I bought the piano for $100 =
for the
experimental value.</FONT></DIV>
<DIV><FONT size=2> There's a technician in Utah who =
repairs
cracked plated with great results, Salt Lake City Chapter, name is =
Young, I
believe. Great guy. Rick Baldassin knows him. Anyway, =
he told
me how to repair it, I didn't have the correct welder and fixing it =
exceeded the
vaue of the piano so I scrapped it. For what it's =
worth.</FONT></DIV>

<DIV><FONT face=Arial>Dave , Just a guess, but from your description =
and
careful inspection , I'd suspect a sudden change between the pinblock =
and the
plate flange. Perhaps some type of glue joint failure ,especially if =
the block
is in sections.That hitch pin area does seem suspicious, but if =
the
plate was broken or had a crack, it would seem to me that tuning =
stability
would not be possible at any pitch. I'm thinking that any failure in =
that
block, back post, fillers etc assembly would be loud,and create the =
changes as
you describe. Maybe the plate flange is what cracked? Late night =
speculations
