---------------------- multipart/alternative attachment Hi Vince I think it has more to do with the pressed felt over the woven felt. On the other hand it reasonable to think that springiness in felt is, well... springiness. I'm not clear about that I only know what I heard & felt on my D. I think Ric's comment about the key stick acting more like a catapult where the front end comes down on something solid and stays put even though the back of the key still may be in a slight state of flux,does makes some rational sense of what I think I'm perceiving. I can't wait for more experience with this. If you have a piano that's familiar to you & you know it's sound well & all you do is change the punchings & there's a tonal change then this is the perfect A-B comparison to be relied upon as proof. It's a repeatable experiment. Regards Dale Erwin Vince writes I wonder if pre-compressing the punching's would give similar results ... pre-compressing by stringing the punching's on a slender threaded rod, then with washers between the punching's and wing nuts, squeeze the whole thing together by tightening the nuts, and storing them that way until needed.
