Flexy S&S D Keys

[Delwin D Fandrich]

Have him or her go back to the August and December 1996 Journals and read the
two articles I wrote about energy losses in piano actions. In one of those
articles I described how to improve (I realize the idea of "improving" anything
to do with the piano is subjective so perhaps I should just say "change") these
keys.
 
Basically I removed the so-called Accelerated Action "rockers" and replaced them
with normal thin felt punchings. I then used the space gained to accommodate
maple plates of equal thickness (4 mm comes to mind but you should check) glued
to the bottom of the keys. Did wonders to "change" the performance of the action
and the piano.

I have an associate that has a 1970s S&S D with too much key flex. I have no
direct experience with this, but I am aware of the situation and that some folks
have had success by beefing up the keys. I believe I believe the most popular
patch is to install extra-long hardwood key buttons. Is that the best fix? I
wouldn't want to do that task. Where/who is the best place to send keys to for
the recommended fix?
 
Thanks.
