Steinway Quality ?

[jolly roger]

Hi Ric, 
           It will happen every time, when the factory does not address the
friction, and fit issues before weight off.
 For run of the mill production give me a CNC weight off any day of the
week. At least it ends up in the ball park.
No doubt you will a great improvement.  As a crude rule of thumb, if a
weight is more than an inch away from an adjacent key weight I start to
look and question.  Mark the lead positions, pull the stack and check front
weights. If they are close, I then recheck capstan and friction.
Just my 2c worth
Roger
