    Hi List ,

    from time to time I am tuning some Ukrainian vertical pianos which =
have terrible hard and jumpy tuning pins...
    Question :
    Is there some home made mixture (applicable like pin tightner ) =
which can help reducing tuning pins friction ,so I can tune them more =
easily later ?
    Best regards to all ,
