Lost Motion and Touchweight

Patrick,

I adjust the lost motion with some degree of regularity, but I never got the
response you did.  It does seem logical, however.  When you've taken out the
appropriate amount of lost motion, the far end of the key starts working almost
immediately, unlike before.  This could very well be causing the heavier touch
as she perceives it.

What to do?  That's a little tougher, since it seems unethical to throw the
piano back out of regulation to please the customer.  But it's her piano and we
want to please our clients.  I don't know how involved it would get to leave the
lost motion as you have it and work to lighten the touch other ways, and having
done that she may *still* be unhappy.  I think I would probably just undo the
work and be done with it.  Certainly a predicament, though.

Regards,
Clyde
