Knuckles

[Jon Page]

Thanks  Bill,
The bulk of the thump is on jack return. Now that you mention it, I can take
off the top action and tweek those a little too.
Last month I had an 20-30 yr old Acrosonic in the shop. There was a clicking
that was difficult to trace, it sounded like hard glue on the butt felt. It
turned out to
be the leather. Somekind of composite material which turned stiff, at least
that's
what it looked like. Once the rewarding task of replacing the buckskin was over
with, the piano has a rather smoothe touch.
