David Verdigris infected action parts are primarily found Steinways from the 1930's. To answer your question directly, yes, you could replace just the parts that are effected, like the wippen flanges, and it would save the customer some money now. But sooner or later these parts will need to be replaced anyway, so while the customer would save some money now, it will be more expensive later on.

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.) --David Nereson, RPT -------------- next part -------------- An HTML attachment was scrubbed...
