Dear Calin & Group, Of Touchweight Metrology note... The lowest friction weight I've ever measured was 1 gram on a Blutner Patent Action. F = (D-U)/2. This means that only 1 gram of the downweight goes to overcoming friction as compared to 10 to 15 grams which is normal for a Herz-Erard type action. The lowest Friction Weight I've ever found on a Herz-Erard was 4 grams on a Bechstein with very free flanges and key bushings. David C.
