If the majority are off center, look at stack placement. Many-a-time I've shimmed it towards the bass, the thickness of a piece of veneer may be enough to make a difference. Look at action orientation too. Look at how the shanks align over the rest felts/ends of wips since knuckles to rep levers is OK. I assume you are intending on moving the capstan back on the key by saying you'll need assist springs to accommodate the touchweight. I have always encountered the opposite on B's. I don't recall a B which didn't have the jack burying into the stop felt, too high KR causing excessive wippen travel. Don't be surprised if you have to relocate the heel as well. (Obviously the b/r was routinely placed too far forwards). Regards, Jon Page
