vertical damper springs

[jolly roger]

Hi David,
              Addendum to my previous post: With the action in the cradle.
I push down with the finger of the gauge, at the point where the damper
wire leaves the damper lever. that way I'm sure of the same leverage
position on each damper.
Caution: some verticals have 2-3 sizes of damper spring wire, heavier gauge
in the bass. So you can expect obvious jumps in tension for different
registers on some pianos.  In this case you have to resample and recheck
the results, where the changes take place.

>The question is how do you measure upright damper spring pressure?  Does
the spring gauge previously mentioned have a hook that comes in between the
hammer shanks and pulls on the spring to measure tension?  If too high in
comparison to the neighbors, one pushes in on the spring and re-measures?
Too weak:  spring out of groove and pulled between damper levers to
strengthen...This all seems doable ...
