[pianotech] Kawai Grand w/Steinbuhler 7/8 Custom Keyboard

Exactly. That's the biggest problem with regulating these actions. If one 
key height had to be adjusted the bass or high treble section, the entire 
section had to be lifted out.
At one point I had introduced the idea to him about considering the concept 
of key height adjustments with an adjustment screw similar to what Ludwig 
pianos did at one point. If the key height  could be completed from the top 
side, then these issues would be not ritard the regulation process.
