Case separation or delamination question

[Z! Reinhardt]

If the piano is still warranty, contact the dealer and the manufacturer.
Chances are that the manufacturer will want the piano back or at least want
to know all about it.

The one time I encountered rim delamination, the piano had a very strange,
thin tone.  When humidity conditions were just right, the piano had a
terrible buzz that completely destroyed the tone.  A dealer technician
thought he would flip the piano over and fill the crack with epoxy.  The
manufacturer demanded that the piano be returned to them at once.

At this time, I'm not aware of any successful "fixes" to this problem.  I
should think any space between laminations would be a source of potential
problems.

Dear list -

What is your approach to dealing with separation of the inner and outer
rims of pianos such as Steinways?  How evident does such a condition have
to be to be of concern (any) to you when rebuilding?  I suppose my question
is directed primarily towards rebuilders, but don't let that stop you if
you have a strong opinion. I attempted to look this up in the archives but
found nothing of relevance under 'delamination' or 'case
separation'.   Also, I wonder how often you see this condition in new
pianos (only a few years old)?    Thanks -
