[pianotech] Jack Springs

[John Ross]

I guess you are right Wim, I am just enquiring about others  
experience. Ethical is obviously the wrong word choice.
It is from Schaff, item number 527A, upright jack spring.
The physical properties are equal taper from top and bottom, to a  
compacting of a couple of coils, in the centre, like each end.
The old springs were a double at each end, and the winding went wider  
in the middle.
