The question remains, at what point in the travel is the best place to take the reading." David, You're mixing "resistance" with "mass". IMO, each should be measured = separately before measuring together. I do understand what you are = trying to accomplish and I agree with your reason(s). I should think = that a careful measurement in relation to the mounting of the back = action and the lever movement will give you the perameter for deciding = the "area of arc movement", (for lack of a better term). I don't recall = seeing any specs/stats on this sort of measurement, although there more = than likely is a list somewhere.<G> As for how much it takes to shut down a note...that depends and so many = variables, such as mass, density of felt, etc. I'd be interested in your findings, once you solve the initial = question(s) at hand.<G> Best Regards, Joe Garrett, R.P.T.
