[pianotech] Question about an old action damper and jack

[Jon Page]

The drop screw looks like it is turned to apply pressure against
the wire to hold it in place.  You could install sockets in the
top flange for a more positive grip.

Jack rest buttons with adjusting screws can be retrofitted along
with the spoon if you don't want to fuss with the rest felt.
