Thank you Mr. Foote for you reply! Ed wrote: Tht would be "deviation from parallel". So that is the technical term for it? Ed also wrote: I don't know about this. Gravity doesn't care how big something is, ie. a big steel ball doesn't fall any faster or slower than a smaller one. The gravity-based restorative force on a large hammer are no different than on a smaller one, however, given equal friction in both systems, the additional mass of the heavier hammer will actually give it more advantage over the friction, and it should fall faster. (notice, that with equal amounts of verdigris in a piano action, the topmost treble hammers will return much slower). Haha, I know that gravity doesn’t care about size or weight. Neither does my gf. However, in a badly balanced action (if the measurement I’m asking for is too small or even negative) a heavy hammer would out-balance the butt and the back stop and it would tend to tip forward. I forgot to indicate that I was referring to a problem case where the action rail might be too far from the strings. Hope this clarifies further! Best wishes, Andreas the Swede Ps. Just the other day I spoke with my mother and she had just been to a very amusing afternoon lecture. The lecturer turned out to be the Jim Henson’s “Swedish Chef” original. He’s alive and well!! _________________________________________________________________ Express yourself instantly with MSN Messenger!
