With the pedal depressed the range of down weights across the keyboard is 47g (C8) to 67g (C1) and the range of up weights is from about 20g (C8) to 40g (C1). The bump is rather abrupt on most keys.

Thanks, Barrie. I'll take a closer look at those rollers. I measured the down weight on a typical key, or should I say up weight. About 66 g depresses it down to the point of "bump" resistance and an extra 100 g is needed to take it down past the bump to the cushion. PS As it happens, Fred Sturm, Un...
