[pianotech] Lubing Center pins

[Isaac Sadigursky]

Would "OXIDATION" of the Center pin  be correct term?     Or is this  
another case of 'REVERSED" pinning,when Center Pin is rotating inside  
the "Bird's Eye'" and is too tight in the flange felt??  It is a  
common case in some piano and damper tray actions...Complete re- 
pinning procedure is  a must in that case.....  Regards....  isaac
