[pianotech] Baldwin grand repetition spings

[Laura Olsen]

Can't you lighten up the hammers a bit by taking some wood out of the hammer head curve, filing the hammers and maybe even reducing the thickness of the shanks? I've had good luck with this.  Reducing mass at the end of the lever makes asignificant difference, unless this has already been done.  I recommend a good  scale so you can be consistent.
