Keys and MOI

[ed440@mindspring.com]

Jim-

If the hammer line is weighed and weighted to produce a strikeweight continuity, wouldn't that go a long way toward producing a "moment of inertia continuity" in the action stack? 

The only thing left to work on would be the "moi" in the keys, which, by our lengthy and valuable discussions on this list might represent at most 10% of the total "moi."

(If I understand)

Yes, Vince, evening out down-weight, up-weight, balance weight, and
friction, as felt at the keys, does make a big difference to pianists.  I
have done it many times.  But in your case, are you sure you are talking
about "moi" (moment of inertia), and not something else?  If so, please
tell me how you go about evening out total action "moi" while working only
with the keys?

Sincerely, Jim Ellis
