[pianotech] Verdigris - again

[William Truitt]

No, I have not.  Since that time, I have sold the jobs replacing the parts.

Rebushing is different from entire flange replacement though.  Have you done
it with replacing the entire flange.

That is my experience also.  Years ago I rebushed a Steinway upright's
action centers for verdigris, didn't see the piano for about 4 years, and it
was right back again when I did come back.  How quickly it returns depends
how bad the contamination was originally and the humidity conditions that
the piano goes back into that tend to favor the prospering of the verdigris.

 

Bottom line:  It's going to cost the customer a fair amount for you to do
this repining and rebushing.  You must tell them that you cannot guarantee
that the verdigris will not return.  If you do, then you are on the hook.
Tell them the only way you can guarantee it is to replace the parts.  That
may be the ugly, expensive truth, but it is what it is.

Changing the flanges is a waste of time. The vertigris is in the felt

and the wood surrounding it.

Is that actually true?  I know that rebushing the flanges is a waste since

the contaminants are in the wood of the flange but since the lubricant used

was originally in the felt of the flange bushing doesn't replacing the

flanges take care of the problem?  If not that presumes that the lubricant

continues to migrate out of the birds eye and I wonder if it was ever there

to begin with.  Anyway, I've not tried it but I wonder if anyone has done it

that way. 

 

I was thinking grand flanges. But even with changing upright flanges, the

vertigris is also in the butt and will again migrate out to the bushings.
