Richard West rote, 7/9: <<Are we, as piano technicians, reinventing the wheel? It seems we are finally discovering action geometry as the latest thing in rebuilding. Manufactureres have been inventing the wheel, so to speak, for centuries. Are we, as piano technicians, reinventing the wheel? It seems we are finally discovering action geometry as the latest thing in rebuilding. Manufactureres have been inventing the wheel, so to speak, for centuries.>> We wouldn't be having to reinvent the wheel if some manufacturers showed better sense in their choice of leverages (S&S pre-84 shank) and hammer weights (Renner's Gross5). We wouldn't have to be "discovering action geometry as the latest thing in rebuilding" if we didn't insist on putting 1995 parts onto a 1895 keyboard. Don't worry, this is no Spring fashion. If you can measure it, you can control and regulate it. This I have learned at every step of the way with David Stanwood.
