Ron the number of key weights is a dead giveaway. You have a leverage problem. The way NY sets up their actions is to set the key frame to the case. set the stack to the strings and locate the capstans to the wippens. There are two places where a key leverage problem can occur. In Germany they fit the stack to the keys the capstans to the wippens THEN fit the action in the case and to the strings. They get the action right before putting it into the piano. THey therefore have very consistent actions. Check the spread action measurement; greater than 4.422 and not greater than 4.440. Hammer weight measured from perpendicular line through center pin to center line of hammer with shank horizontal with frictionless contact points with hammer resting on a digital scale. David Stanwood has published hammer weights in terms of loud, medium and soft tone with ranges. These numbers subjects to quadratic equations results in curves. Plotting samples of your hammer weights will show where they fall on these curves. Based upon the six weights in the bass indicates there is a leverage problem that may necessitate the relocation of the capstans by as much as .125". Pianoteck has all the tools needed to do this evaluation. Newton
