Hi Terry, file as you suggest and coat with CA. My choice is the thin.

  Don't know exactly why it happens, but I run into it quite a bit in =
Florida. Growth is arrested temporarily by filing. If you file, do it =
with a vacuum on. Don't breathe dust! Lead is not good for you unless =
you want to go crazy like Beethoven or Van Goh! This is a great =
procedure if you want to go back and do it every few years.

  If you want to fix it only once, remove old lead and install new.

  I wonder if it would help significantly to put a quick coat of thin =
epoxy on the side of the key to cover the freshly filed lead, or even =
the new lead?

    Hi List

    Got a problem with growing leads in the keys of a Herburger keyboard =
fitted to a Schimmel grand piano.

    Does anyone know how to arrest the growth problem ? Can drilling a =
small hole in the middle of the lead help ? What is the major cause of =
this oxidisation ?

    Thanks

    Tony Caught
