[CAUT] Damper pedal noise

[Chris Solliday]

I'm not sure but it lately seems to have a slightly medicinal odor. Perhaps
a wind player can shed more light. BTW the leather piece is not necessary as
long as you sand the lever flat on top. Or an under leather or felt can be
added. You just don't want that spring digging in. There are choices.

I would add, to make sure the spring is tight.   What makes up cork grease?
