I am not sure what the numbers mean. do you have tension in pounds and string length in millimeters? So it looks like 97 lbs for note #85. That seems off by 60 lbs since most top notes are around 150 lbs, 170 at the most. --ric ----- Original Message ----- From: <Bdshull@AOL.COM> To: <pianotech@ptg.org> Cc: <Bdshull@AOL.COM>; <Raoul.J.Burchett@kp.org> Sent: Friday, November 10, 2000 3:53 AM Subject: Steinway Style 2 data (was Short Scale/Decal for 1866 Steinway) > List: > > Here is a .dbf file from PScale of the Steinway Style 2 data, as I promised > at least a few days ago. > > PScale is designed for modern wire.
