No Newton. The solution is is to measure upwt/downwt with the spring disengaged, and find the BALANCE WEIGHT as their average. If the complaint key has a balance weight that is much lower than adjacent keys then remove lead to make the BALANCE WEIGHT the same as adjoining keys. >If there are helper springs adjust the weight to be the same then adjust the >spring tension until the down weight is the same. Adjust the spring to make the BALANCE WEIGHT the same. Newton... I'm suprised to hear you of all people advocating the Downweight System! BALANCE WEIGHT factors out the friction!! It's the BALANCE WEIGHT!! BALANCE WEIGHT!! BALANCE WEIGHT!! BALANCE WEIGHT!! BALANCE WEIGHT!! BALANCE WEIGHT!! BALANCE WEIGHT!! BALANCE WEIGHT!! BALANCE WEIGHT!! BALANCE WEIGHT!! David Stanwood
