Just started a basic action job on a Steinway C Hamburger :) Nice
piano but getting a bit uneven and noisy as time goes by.. about 20
years old. Folks have been complaining for a long time now about it
been "heavy" or "sluggish".

The before anything is done measurements are as follow for selected
notes. I should actually say that I cleaned the action and ran some
proteck on action centers and capstans, and teflon powder on
knuckles... which improved the friction a good deal. DW was about 3
grams higher over all, UW was about 5 - 8 grams lower... here the
change was a bit more uneven. BW shows around 49 gram average.. a
bit up and down for  but not so uneven. The Front weights seem a bit
high and curve off less then Stanwoods graffs would have them.
Strike weights are on a rough 5.7 Strikeweight Ratio curve.. also a
bit heavy but probably good soundwise for this piano... its in a
small concert hall.. lightly damped  acoustics.. seats 100 folks.

I wont be able to fool with the capstans on this one... probably
dont really have to anyways.. but any other advice on how to move
towards a more balanced ratio would be appreciated and off interest
to those who are aquainting themselves with Stannwood basic
principals. So if you got something to say...grin... do so :)
