Thanx much!! >michelle > >stranges@oswego.edu Michelle, If the jack is being buried into the stop felt at the end of the lever you have one or more contributing offenders: Key dip too deep Hammer bore long Hammer blow too short Knuckle too close to the center pin Capstan too far back on the key On a S&S B, I would suspect key ratio (capstan placement). There is one here which has the jack jamming into the stop felt and blocking the key about 1/16" above the punching (talk about springy). This piano needs a shallow dip and long hammer blow. The capstan would have to move more than 1/4" forwards to have this action regulate properly which would entail moving the wippen heel. The customer wishes to live with it the way it is. Unless you are prepared to remanufacture the action, fudge on the settings for dip, hammer blow and maybe a little extra letoff.
