Ron: And how will the eventual marring and tarnish affect tone? I personally use brass because it's affordable, workable by my methods and machine capabilities, readily available, and exhibits a practically low coefficient of friction in contact with music wire. Cosmetics don't concern me in this instance, and potential tonal penalties so far remain undefined, unless you have something to offer along these lines. IOW, until you have a fix, is it broke? Jude: What concerns me is damage to the brass as a result of the string compression that one finds on old pianos that use this system. This includes brass aliquots that have even been plated. What if the string spacing needs to be refined? What happens to the profile of our termination? Then again you see the same damage to the cast iron v-bars. Uggg! Only questions, so few answers. :) Jude Reveley, RPT Absolute Piano Restoration, LLC Lowell, Massachusetts (978) 323-4545
