This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment I don't have a drawing, but words should be pretty darn precise: There are two magic lines to consider. One runs from the bottom of the = key at its fulcrum (center rail pin) to the center pin of the wippen = flange. Ideally (least friction), the point of contact between the = capstan and the wippen heel cushion will lie along this line at half = key-stroke. The other magic line runs from the wippen flange center pin = to the hammer shank flange center pin. It is most efficient if the = contact point between the jack and knuckle lie along this line at half = key-stroke. Terry Farrell Does anybody have a picture or drawing showing the "magic line" in the = action, going from the capstan, I think? Andre Oorebeek told me about that yesterday but I would really like to = see a drawing of it. Thank you, Quentin Codevelle ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
