Hey Jim, Whew, you gave me a pot of stuff to chew on concerning this verdigris thing. I can address some of your questions. >Have you never seen a S&S, or other, whip where the flange had verdigris but >the jack and the balancier rail did not? Yes, but I have seen some where the jack had verdigris. The balancier rail, just don't remember. >What was the difference in the >centers? Was it the waxy feel and look of the flange as opposed to the clean >dry feeling of the other parts? If you heat the flange does a waxy substance >come to the surface ? On the other, verdigris free, parts does any wax come >to the surface when heated? I don't refute the existence of a waxy substance at at. > When you remove the flanges, whip or hammer, does not there appear an >outline in verdigris where the flange was while the space between flanges is >free of the gobby green stuff? Where does the build up of verdigris come from >on top of the material applied to the hammer rail and why doesn't the gobby >green stuff show underneath the material on the rail as badly, if at all? If I understand this, the only instances I recall are the verdigris appearing under the rail cloth, not on top of the rail cloth. In an earlier post, I contended the rail cloth was a factor, then Wim mentioned the wippen rail as a culprit, so I retracted that statement. Now I will say, that when I've experienced verdigris, the greatest area of concentration of verdigris has been the hammer rail area when it has had a rail cloth, with the wippen flange rail being next, but not nearly having the concentration of verdigris. >If >the hammer rail itself was subject to verdigis formation why isn't there a >build up of verdigris on the front, back and bottom as there is on the top >where the flanges touch? >If the whip rail itself was subject to verdigris >formation why isn't there a build up on the top, bottom and front as there is >on the back where the flange touches? This is an excellent point, one which I can't even offer a speculative answer. Thank you for taking the time, and for offering a test with the two screws. At this new moment in time, I still am unable to grant that you are completely correct about your reasons, but at the same time I can no longer allow myself to entertain the possibility that you are in error about your reasons either. Appreciate your personhood, Keith A. McGavern kam544@ionet.net Registered Piano Technician Oklahoma Chapter 731 Piano Technicians Guild USA
