Fixing squeaky keys on a Kurzweil Mark 10

    Half the keys squeaked on a Kurzweil Mark 10
    when the keys
    were played. I noticed in looking
    at the mechanism at the end of the keyboard
    where I could see
    that the keys were squeaking because the
    vertical tab that is part of the key was rubbing on
    the felt on the rotating
    weight that gives the keyboard the
    weighted feel. It is
    supposed to rub there as it pushes on the
    weight but apparently the
    felt had dried out or something and was
    making the squeak.
    The solution was an ordinary shishkabob
    bamboo skewer,
    a very small piece of duct tape and some graphite.
    First I removed the front metal cover just under the
    keys. This is a couple of inches wide and just
    longer than the keyboard. I put
    a very small piece of duct tape maybe 1/4 inch
    long over
    the very end of the skewer and made it stick out
    from the skewer less
    than 1/4 inch. Some dry graphite can be
    put on the tape
    from a squeeze bottle and then the skewer can
    pass through the
    slot under each key and pushed in until it comes into
    contact with the tab on the key that is squeaking.
    This lets you know you are just over the squeaking felt.
    Then turn
    the skewer over to turn the tape upside down to dump
    the graphite on the felt pad
    that is now underneath the tape on the skewer. Press
    the key to work in the graphite. Sometimes it helps
    to push the key very fast repeatedly to distribute
    the graphite over
    the felt.

    I just bought a Kurzweil Mark 10 from Craig's List and over 1/2 the keys squeaked. I removed each squeaky key one by one and swabbed vaseline over the red felt and surrounding metal. No more squeaking...yah!
