Actually, I saw this rather brilliant bench top, built reportedly by Del, once at
a piano shop in Seattle. The hitch here was that you were to bed the keyboard
before takeing the piano to the shop. Once this was done this neat little
contraption was "bedded" to the keyframe. Thereby the fully assembled action was
resting on a platform which nearly perfectly matched the bed in the piano. I got
to use it once do an action prep on a small Petrof grand. It all worked out
pretty good. I was able to do pretty presise regulation on the bench, especially
key leveling was a snap, and that saved a lot of time. I have thought many times
of building one of these myself, as its not too difficult a task, but have never
gotten around to it.

I agree wholeheartedly
