certainly seems like a precursor to the SD-10, sharing the vertical hitch pins and front treble termination bars (the difference being that your D has a the termination bars as a single piece filling the whole treble section, the SD-10 has the individual bars that can be adjusted forward or back).  But the function is essentially the same between the two.<o:p></o:p></span></p><p

style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>The closest I can come to your instrument is a 1988 SF-10 with the treble termination bars.  It suffered from rendering issues like yours, but was also leaky and full of falseness.  Letting tension down on a string and moving it to a side revealed significant grooving on the V portion.  I priced a replacement set of termination bars from Gib-greed – they wanted something like $1200 for a new set.  <o:p></o:p></span></p><p class=MsoNormal><span

I did was let the tension down on the individual note, remove the coil from the tuning pin, and pull it through the bar and out of the way.  Then I took a strip of emery paper and reshaped both terminations – the V bar area and the front termination seen in your picture.  I followed this with crocus paper to polish it.  Then fed the wire back through, hitched it on the tuning pin, tuned, etc. etc.  <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>I was fortunate to have on hand a number of termination bars from my time as a dealer, and did replace a few that were too far gone to clean up well.  <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>The result was that the falseness disappeared and the wire would now tune normally.  <o:p></o:p></span></p><p

performing the operations with the bars in position on the plate.  Kiss your back and neck goodbye, you will need transplants after you finish this job, if you don’t decide to put yourself out of your misery first.  <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span

esteemed colleagues:  I am tuning a 1968 Baldwin D grand (9') today and am having quite a bit of trouble with string rendering in the two treble sections. This piano has the unusual treble forward terminations that Baldwin has used (pictured below) - I have heard of them before, but this is the first one I've actually run across. I will be going back to the piano later this afternoon to finish. I will be trying some Protek on the two forward termination bars.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>String rendering on the treble of this piano is very unusual. The treble was a bit flat. First I nudge the tuning pin to turn and bring the pitch up just a cent or two above target pitch. Then when I go to nudge the pin to lower pitch to target, as I put pressure on the tuning lever to lower pitch the pitch will actually rise about five cents before it starts going down. Same thing if the pitch is a couple cents sharp - lower pitch just below target and when you apply pressure to raise pitch to target, the pitch actually drops five or so cents more flat before rising.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>And then of course, after you think you have the pitch where you want it and the pin is settled in a neutral position, the pitch goes five or more cents sharp or flat.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>This is not your typical Yamaha C3!<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Does anyone have any other tips or tricks to offer a slightly frustrated piano technician?<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Anyone knowledgable on the evolution of large Baldwin grands?
