[pianotech] Key leveling

[David Stanwood]

Hi Jack Et al,

Have you or anyone else seen the key levelling system that utilizes a 
long screw that goes down through the key button/key onto the back of 
the balance rail punching?  Turning the screw in or out makes the key 
go up or down.  I'd love to get a photograph of this for a class I'm 
developing: "Off Center Balance Rail Bearings" for PTG Institute 
2012 at Bellevue:
