touch weight changes

[Carol Beigel]

I eased the balance holes in the bottom of the keys.  I will also take the
advice to use teflon spray on the key bushings.  Meanwhile, I will acquire a
nice set of accurate gram weights and read up on how to make all the
necessary measurements.  I think I may also design an Excel spreadsheet for
my Ipaq that I run PocketRCT so that I can enter the measurements and let
the computer do the calculations.

Through the years I have sat through David Stanwood's classes on this
subject, so I will now try to find my notes and class handouts.  I never had
a reason before to really know about touch weight until now when pianos will
be replaced or not on my say so. I like being able to make decisions based
upon concrete, mathematical data - not brand names!  I will also go to the
church and measure the touch weight on the piano my client finds appropriate
so we can compare numbers on other pianos.  Apparently, it no longer is
enough that a piano action feels fine to the person buying the piano if it
can change radically after purchase!

My thanks to all who have given their imput, and I am quite ready to receive
more advice and pointed in the right directions to learning all I need to
know about friction and balance weight in piano actions.
