<html> <body> Hi Ric,             Some of that noise is coming from the card punching, slapping on the frame. That's why I mentioned putting a little dab of white glue on the bottom of the heavy card punching. We have done quite a few piano's this way, and like the results. The white glue has a slightly rubbery quality to it when set, and help to cushion some noise.  Measure a note in each octave, old punching's, plus old felt punching's, with a digital caliper. Then select a card punching that will give similar results with the crescendo punching.   Repeat for the sharps, they will be different.

I find that the addition of a 1 mm thick extra felt punching under the crescendo punching is enough to quite any noise considerably without compromising the effect of Andres punchings much at all.  No doubt there is some effect... but I still like this combination better then soft green cloth punchings.  I make my 1 mm punchings myself when I need them out of bushing cloth.  1.1 mm is what they say the stuff is actually.
