Hi Miark Looks to me that what you have here is a set of Strike Weights that start off in the upper half of the middle zone (Bass), and pretty evenly graduate to the upper part of the high zone (treble). The Front Weights echo this quite well in a general sense, starting off well below FW maximums given by Stanwood (bass) and ending up well over them in the treble. Suprises me a bit that the Down Weight on a relatively recent Steinway is so high above 50 for so much of the piano, and so very uneven. The Hamburg factory at least is usually a bit more clever at this much then the below figures. But let go. Looks to me you are looking at a about a 6.0 SW Ratio, and perhaps some significant uneveness there. Check the knuckle allignment and placement of the capstans for eveness, and of course make sure notes that stick out are correctly regulated. Otherwise... seems to me that you could pretty much even out the SW curve to a Top medium curve, and adjust Front Weights to give you about a 39 BW without too much difficulty and without creating a problem with too much lead as well. For much of the piano, especially the treble section you'd be subtracting FWs as well as SW's. You could get into changing knuckles (and evntually knuckle position) if you want to. If the existing ones are worn and flattened the by all means. But perhaps this is not so crucial. Depends a bit I suppose on how much money you are working with :) The entire existing SW set would be nice, as well as a few samples for Key Ratio and Whippen Weight.
