Fr= om C1 - F2, the down weight is between 52 and 55 grams. The rest is between = 47 and 50, with a few 45's and 46's in the 7th octave. Upweight is generally= between 27 and 30 grams, with some as low as 25 and a couple as high as 34.= </DIV> <DIV> </DIV> <DIV>The Piano Action Handbook says down should be 51-52 in the bass graduat= ing to 47 in the treble, with up weights at 20. After Christmas I'm going to= lube all centers and check for pinning. Hopefully I'll get better upweight = measurements. Is this about what you guys are going for? BTW, is TW the diff= erence between down and up, or am I missing something in the calculation?</D= IV> <DIV> </DIV> <DIV>Wim </DIV></BODY></HTML>
