[pianotech] How to analyze an existing tuning

[Paul McCloud]

Yes, a good technique.  Use the pin as a kind of spring to counter the pull of the string.  Just don't overdo it.  Yeah, gentle.  
I always try to keep my lever as close to the string direction as I can, especially in the tenor section.  Then you eliminate the influence of the pin bending fore/aft which affects the pitch.  It helps stability a lot.  I find that a 1:30 position of the lever in the capo section works well to the top treble.  More friction there.  Works for me.
Best,
Paul

Thank you very much Paul. Y ou have confirmed my thoughts on testing the pin/string stability, namely, the wiggle/waggle test of the lever on the pin and the hard test blow after the final movement of the lever. With regard to the wiggle/waggle movement on the pin to check if the pin/string unit is in the stable zone, I recently read a post by Isaac Oleg on Piano World stating that he uses a gentle pressing down and pulling up of the lever, which is facing in the direction of the strings, when checking the pin/string unit stability.
