Electric Key Pounder?

[Delwin D Fandrich]

Yes.  We have one that plays each note on the keyboard two times a second
(at the low end of forte) for as long as we set the timer.

We use it at least twice on every piano.  Once after rough regulation and
again after fine regulation for a period of at least two hours.  It does
help to stabilize things quite nicely.  It also brings out certain
problems -- such as binding action centers if the action maker puts too much
graphite on their bushing cloth.

I'd say more about its design, but I'm not all that happy with it.  Too
complicated.  But it does work, so I'm not about ready to design another.
