I am surveying some of our grand pianos, in the interest of finding out what weight of hammers might be accommodated with existing leverage, front weights at 80% of the ceiling identified by Stanwood, and a 37 gram balance weight. The three instruments I have measured thus far are calling out for (as far as this approach is concerned) a finished weight at hammer 1 of about 9 grams or less. This would correspond to Stanwood 1/4 medium, or Curve 6.
I do understand that strict adherence to such an approach becomes less and less necessary at the outer ends of the scale are approached, but I am curious as to what hammers you all reach for when faced with weight requirements in this neighborhood. I recently installed a set of Renner Blue Points G4U 16 lb hammers, and was only able to grind my number 1 hammer down to about 10.5 grams. I was aiming for something in the neighborhood of Stanwood 1/2 medium (Curve 7) that would call for a hammer of 9.5 grams. I do realize that the Blue Points are available in a 14 lb configuration as well.
What options would you be inclined to list?
