[pianotech] parts replacement due to vertigris

[Gerald Groot]

I agree.  Years ago,   I tried it without replacing all parts and eventually
some of it did manage to creep its way back into the flange again.  Replace
it all and be done with it.  Saving money is is spending more later doing it
twice IMO.

Adding to what Wim said, verdigris IS capable of spreading from a
contaminated birdseye to the flange.  Replace the parts and be done.  It is
penny wise but pound foolish to not replace the parts now.  I can guarantee
new parts to be free from vertigris.  I won't guarantee new flanges to
remain free from verdigris using the existing contaminated parts.

FWIW

  In a case of vertigris, can just the flanges (and of course, center pins)
be replaced?  It seems the parts most affected by vertigris are the center
pins and the bushings in the flanges or shanks.  There might be a little
vertigris in the birdseye of a butt or wippen, but will that spread to the
bushings of new flanges?  I could see replacing an entire set of wippens if
the jack and balancier pinning was also corroded in addition to the wippen
flanges, but if not, do ya really have to replace all the wippens?  (I'm
trying to save the customer money by just replacing flanges and not having
to replace wippens, or in the case of a vertical, the hammer butts.)
