[CAUT] Andres punching tested

[Wolfley, Eric (wolfleel)]

I haven't heard any of the attempts to explain how firm frontrail punchings
might affect tone...I'm curious since there's (hopefully) no connection to
the frontrail punching during escapement or when the hammer hits the
string...is it some kind of psychoacoustic phenomonem? Please elaborate.

I'd agree... yet there is an elasticity to them as well not encountered
with other punchings... or so I seem to percieve these.  You get this
really nice feeling of hitting a very solid bottom while also
experiencing a very pleasant <<spring>> back upwards... nothing too
dramatic mind you, but noticible and nice.  Then there is the
unmistakable change in piano tone... harder to find an explaination for,
but some of the attempts made so far seem to have some sense to them. In
anycase its there.
