Heavy action

Actually I know already that the hammers are too heavy, I just don't
think I can remove enough weight from the hammers to make enough of a
difference.  Maybe I can taper some more, and add just 1 weight to
the keys, I don't know.  I don't want to spend a lot of time/money on
it as I hope that in the long range this piano will be replaced.
