  Hi Jon,

  Sounds good, but here still, one has to weave the Hart spring tool =
through the tangle of butt springs (although that might be easier than =
the regular damper wire regulating tool) - how to do that without =
mangling things - or should I just count my blessings that I did not =
choose to be a surgeon?

    Hi Terry,
    I've used my Hart spring regulation tool to adjust upright damper =
wires - either pushing or pulling on the damper head while carrying out =
the opposite motion with the tool.  For a better description, see the  =
PACE upright regulation manual.


    Respectfully,
    Jon




      Did a full damper regulation on a little trashy 1985 Conn console =
yesterday (first time on an existing action - I've done it several times =
as part of an action rebuild - way easier when you are starting from =
scratch). I'm so proud of myself! I think it would be easier to design a =
new piano! It was a teacher's piano and she said that the dampers had =
never worked right - jeez-oh-petes - when depressing the sustain pedal, =
the bass dampers were an inch off the strings before the treble dampers =
lifted, and on most notes, the spoon engaged the damper lever right at =
the start of the key stroke - she also commented that the action was =
heavy. I know I didn't get it to concert-level accuracy, but the whole =
system ended up pretty darn functional and in the right ballpark. She =
gave it a try afterwards and remarked that it was now doing what it =
should.

      My question is this: how does one go about bending damper-head =
wires on verticals without trashing the hammer-butt springs - not that I =
disturbed a single one of course - but I can see the potential to do =
that.   ;-)
