    I know this has had some discussion in the past, but does anyone know WHY these parts have a strong tendency to tighten up and become difficult to operate?

    Renner has been around for a long time. I have a hard time believing that it is simply extreme seasonal humidity changes, when many other (of course not all) action parts remain relatively trouble free.

    And then, of course, is the only solution re-pinning? Even on a relatively new instrument?

    Comments?
