This will allow you to see the sostenuto rail and tabs at = the locations closest to the adjustment points using a flashlight with the = action back in place. <o:p></o:p> <o:p> </o:p> Before sliding the action back in, = loosen the screws and bolts that hold the brackets just enough to allow the = rail to slide in and out when tapped with a screwdriver blade. With the action = in and cheekblocks in place you can use a thin long bladed screwdriver to reach down = through the strings and tap the brackets to position the sostenuto rail correctly. = <o:p></o:p> <o:p> </o:p> Of course the rest of the system = needs to be in at least reasonably good adjustment before you begin, IOW, good = damper regulation, nice straight sostenuto tabs and proper amount of throw on = both sustain and sostenuto pedals.<o:p></o:p> <o:p> </o:p> - Mark = Dierauf<o:p></o:p> <o:p> </o:p> -----Original = Message----- From: Piannaman@aol.com [mailto:Piannaman@aol.com] Sent: Wednesday, November = 09, 2005 10:20 AM To: pianotech@ptg.org Subject: Steinway = Sostenuto Adjustment <o:p> </o:p> <div> Liszt,<o:p></o:p= > </div> <div>  <o:p></o:p= > </div> <div> A manager at a store that I contract for requested that I figure out what = what was wrong with a Steinway B sostenuto pedal.  I should add that = this piano was restrung, refinished, new hammers, etc., but the work was not very = well done.<o:p></o:p> </div> <div>  <o:p></o:p= > </div> <div> Turns out, the dowel that goes from trapwork to monkey was not there.  I fabricated a dowel that ended up being level with the keybed in the down position.  I put the action back in and found that the lifting rail = was not regulated properly.  I could not get it right by sliding the = rail in or out.  It either wasn't lifting anything, or it was lifting = everything all of the time.  I did not feel comfortable messing with the = height without any guidelines.<o:p></o:p> </div> <div>  <o:p></o:p= > </div> <div> Is there a trick to gauging the height and fore/aft position without using = endless trial and error?  I know this was a recent thread, so I'll check = the archives as time permits, but I wonder if anyone has any handy advice on = this one.<o:p></o:p> </div> <div>  <o:p></o:p= > </div> <div> Thanks in advance,<o:p></o:p> </div> <div>  <o:p></o:p= > </div> <div> Dave Stahl<o:p></o:p> </div> </div> </body> </html>
