In your case you have = a lot of UW, if you don't have too much lead in the keys now, you could = add a little lead to the front of the key to get the DW down to 50g or = so and still have over 30g UW. How does the capstan/wippen-heel-cushion = interface line up - would moving the capstan help or hinder? Also, what = is the status of you butt springs - the tension there will affect things = also. Do you have a picture of your Knabe? 1890s Knabes are just awesome! Terry Farrell What would be optimal balance weight for an upright? My searching has revealed a suggested lower 40's. I have a 56 gDW, = 37gUW. friction is ~10 grams. 46gBW. I'm thinking I need a 4 gram drop in BW. Sure I know it's just an = upright but I want performance. I'm thinking capstan move.
