Thursday evening I picked up the Baldwin SF10 action and had it on = the bench for a day. The origin of the problem was simple: The hammer bore distance was = 5mm too long for the string height. That's right, the hammers were 5mm = undercentered, and that's after one or two filings! Obviously these = hammers came off the shelf prehung, and good luck to ya'! But the problem was to make the best of it in one day, so I -set let-off as close as possible (gaining nearly 2 mm of powered blow = distance there) -removed the hammer stop rail and set the hammer line to the Baldwin = spec. of 1& 7/8 inches blow distance. -pulled rep. lever regulating screws 1-46 and ground 1.5mm off the tip = and 1.5mm off the top, and replaced them. -ground 1.5 mm off the tops of 47-55. -reinforced the holes of 1-46 with a tiny drop of CA . -replaced and adjusted the hammer rest rail. -and saw that it worked darn good! -ironed the bushiings, lubed the bushings and pins, did some touch up = regulation. -7 hours work, all told. The piano is greatly improved! It has a much greater dynamic range = with less effort to control. The teacher is delighted. He was planning = to sell and replace this piano, now he's thinking about getting new = hammers.... It is a great 7 foot piano. Has the real synchrotone bass strings. = Unlike a more recent SF10 I've worked on, the agraffes are perpendicular = to the strings, the bridgepins and notches are aligned, and the tuning = pins can be turned. This is a great design if it is built right. Sad = to think of what has happened to it. But meanwhile, I get to be a hero, thanks to your help.
