Pedal rod problem

[Joe & Penny Goss]

Hi Kristinn
Some ideas
Find one or two eye screws with a very large eye and use to support the rod,
damping the vibration. Use heavy greese where the rod goes through the eye.
If the rod goes through a hole in the key bed, line the hole with felt and
cut the rod so that the two pieces are inside the keybed hole as the rod
moves up and down.
