[pianotech] rusted underlever screws

[Joseph Garrett]

A thin stream of water dripped onto a 1930's Baldwin small grand. The water
hit two bass dampers, dripped onto their strings, sostenuto rod, and down
onto the damper underlevers. Now the underlever screws are rusted and
impossible to remove. 
 
 
I would appreciate suggestions.

I'd, first, put screw driver blade in slot and give it a good hit. Then,
try turning. Second, I'd do the same, only put some turning force on the
screwdriver and then hit it. That should shock it into turning. YMMV Rust
can really "bond" with wood!
