Action geometry

[Ray Hopland]

Avery;

        You mentioned in an earlier post that the bass worked well.  Those
are the figures that I would go for.  You can always experiment and bring it
back.  You must remember that the height spread is as important as the width
spread.

        I once had a Heintzman that had a schwander action in it so I went
to the Kimball class and took in their grand regulating class, after the
class I told them about the piano and how terrible it worked and they turned
around and said "you have a problem".  So much for the help.  I any case we
had two Kimballs so I carefully measured the pin spread and the height
difference and found that I had to raise the hammer rail by .080" and then
of course I had to close the pin spread difference because of the extra
length created by raising the rail.  Then it worked just fine.

        Hope this helps.
