Touch Weight changes

[Carol Beigel]

It never occured to me to measure the upweight.  I assume you do this in
reverse - put damper pedal down, put a weight on the key, and see how much
weight is sitting on the key as it begins to rise?

Are you saying, that by removing friction (cleaning pins, using teflon
powder on knuckes, protech on hammer lever flanges) to adjust the
downweight, that if the ratio of upweight to downweight is not correct, then
the problem will reoccur when the friction returns?

This is a Boston grand action on a 7 foot piano - only two years old.  I
thought these things were designed by Steinway and built by Kawai and
supposed to be good.  Am I still missing something here?  Thanks for the
responses.
