Andre's Front Punchings vs Schimmels

[Roger Jolly]

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.

Regards Roger
