Newton, Del, Ron O, Ron N and other scholars out there, This might seem like an over-simplified question, but what factors in scaling determines the optimum width of a bridge and the facing in the first place? I have always pondered the reasoning behind the broad width bridges vs. some of the extremely narrow bridges found in all types of pianos. Having rebuilt oodles of instruments, the good, bad, and the ugly, I have yet come to a conclusion as the "why's" vs. the "how effectives" are each design.
