Hi David I dont think its unreasonable too associate Steinways hammer weights as roughly linear as Ray and others do. Certainly the curve is much flater then your own curves. As for whether or not it is their intent as Sarah (I think) ponders is another thing. I would like to comment on Sarahs origional post tho. Assuming there is some value to correlating hammer weight to string mass/ length... or for that matter some combination of that combined with SB impedance characteristics... Stanwoods and other similiar balance formulars still lend themselves perfectly to ariving at whatever key mass is needed to counter balance (static balance) any chosen hammer weight. I would also like to mention that given what we know about the dominance of hammer inertia with regard to the total dynamic weight of the action, the value of very evenly graduated hammers weights is unquestionable IMHO. That said, awareness that both static and dynamic action weight are intrinsically connected in the pianists mind to the far more general sensation of piano output for finger input, which gets immediatly into a host of other issues, is simply a must for any pianotechnician who would successfully employ any balancing method. This fact is probably the main reason pianomanufacturers have carried on quite well without any more sophistication then simple DW measurements for well over 100 years, and why increasing numbers of technicians evidently seem to find themselves content with that basic method. Tho personally I see this as a step backwards. Stanwood pointed the way to a methodology that provides perfect static counterbalancing, which indirectly also supports no small degree of lateral dynamic evenenss. When used judiciously, his basic philosophy can be employed to significantly enhance the sensation of evenness the action offers the pianist. Of that, there should be no doubt what so ever IMV.
