bumps in keys

[Farrell]

I'm suprised others have not responded to this. I have seen many keys where
the lead hole was not drilled completely through the key, i.e. you can see
the lead on one side, but not on the other. When such a lead
corrodes/swells, it will push the thin wooden "cover" out, thus creating a
wooden bump on the side of the key. My low $$ solution is to sand it flat -
if I have only a few, I do it with a file, if I have many to do, I will use
a belt sander or some such device. You don't want to get lead in your lungs.
Just don't breathe it.
