All,
I am working to improve the touch of a studio upright due to a relatively "clunky" feeling throughout the keyboard. Several regulation combinations have not remedied the problem, and I am now considering the effect of capstan position relative to the wippen. On this particular piano, I have noticed the capstans contact the wippens nearly 3/16 inch
posterior to the jack posts (i.e., toward the rear of the keys). This differs strongly from several other studio uprights that I have observed: range from 1/16 inch to 3/16 inch
anterior to the jack posts (i.e., toward the front of the keys), as well as in many vertical action diagrams. I posit a significant change in leverage between a posterior and anterior positions, and perhaps a change in touch.
I ask for your suggestions, cautions, etc. of moving the capstans, other than changes to touchweight, which I understand will change proportionally to the distance the capstan is repositioned.
