[pianotech] How to analyze an existing tuning

[Mark Davis t/a PianoForte Technologies]

Thank you very much Paul.  You 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.   
Regards, Mark
