Thanks for the comments.=20

This piano had recently been moved from So Calif to Springfield Oregon ( =
about 8 weeks ago). It was 8 cents flat on average.

I am suspecious of indnetations on the strings myself. If this is the =
case I am not sure what to do other thatn to recommend restringing.  =
What do you think?

  I tuned a Baldwin H grand the other day with a similar problem.  The =
piano hadn't been tuned for years, and was 30-50 cents flat.  I wasn't =
having a problem with getting the string to move(solved pretty nicely by =
Protek, in my experience), but I was having a hard time moving the =
string to stay where it was supposed to in many cases.  I'd get close, =
then "pop!"  It would move up above or below pitch.  I suspect that the =
strings have small indentations, nicks, or bends in all the wrong places =
as a result of being so far flat.  =20

  Could this be the case with your Schimmel?  Did it require a =
significant pitch raise?=20

    Rendering strings is never a simple issue on pianos that have=20

    equalizing the tension in all segments of the strings.=20

    I doubt the agraffes are necessarily your culprits in this matter=20
    though, but rather the felt between the agraffes and the tuning =
pins.=20
    Of course all the bearing points add to the overall difficulty.=20

    I tune a couple of M&A BBs' with incredible deflection in that area, =

    and it creates definite uncertainty in establishing stability,=20
    especially when a pitch change is required.=20

    There are some pianos a person just has to work at tuning, and there =

    marvelous experience.=20
