Meaning what? No cracks? Is there crown? Do you have adequate bearing?

Count on it!!!

I'm afraid I don't understand this description. Is this flex in it's=20
currently un-strung state?

Certainly you should tackle the problem but I'm guessing that it may lie=20
deeper than just the bridge. More accurately that one problem may lead to=20
another making only bridge work a scratch on the surface of bigger problems.

I don't wish to come across poorly here. I really don't know what level of=
=20
experience you have and I'm only throwing out ideas. It just seems to me=20
that the overwhelming evidence in the filed from this type of piano is that=
=20
there might be other issues. What tests did you perform that make you think=
=20
the problem is coming only and solely from the bridge? BTW, which bridge=20
are we talking about here? Seems like there might be some piece of the=20
puzzle missing here.
