Using a T-impact hammer on these will avoid flagpoling altogether.

  Robert, I know this isn't going to really help you out too much, but =
if misery loves company, you're not alone. Any time I tune a piano with =
coils that high from the block or bushing, I have to be especially =
careful not to "flagpole" the pins. I have found that in cases like =
that, it's easier for me to stand and tune with the hammer parallel to =
the string. Takes some more contorting of the ol' bod, but it's the only =
way I know to get a really stable result. Hope that helps, other than =
that I can only say that I hope somebody else has a better idea, then we =
could both benefit from the discussion.=20

    Hello,

    I would like to inquire if anyone else has observed excessive flag =
poling of Petrof tuning pins.  The piano: Model III.  The place: =
Caesar's Palace in Las Vegas.  The piano is heavily used for moderate =
Jazz, (6-12 hours a day), in a lounge.  The piano is tuned twice per =
week.

    Stability seems to be a problem.  This piano has an open faced pin =
block which means that the pins stand upright and do not lean back as in =
a conventional design.  The coils stand 1/4" - 3/8" above the block.  =
The hypothesis is that the pins may be bending excessively due to the =
high coils, making setting the pins more difficult.

    A possible cure would be to simply set the pins deeper into the =
block,  although this is speculative theory, (particularly since this is =
how it was designed).  Additionally this would add friction to the pins =
which may contribute or create a new problem.

    Anyone experienced with this piano and had similar problems?  If so =
what solution?
