I need help getting the adjustment right on the sostenuto mechanism of a 1918 Sohmer 9 foot grand.
This is a piano that I have been servicing for several years but one section of dampers has always been a problem. I knew that I would have to repin the under lever flanges some time and this past week was the time.
In order to get to the under lever flange screws I had to unhook the sostenuto rod. I got the flanges repinned and back and they work fine, but now I can't get the sostenuto regulated. I have fiddled with it (and fiddled with it; and fiddled with it) but just can not get the tolerance correct.
Any suggestions from the collected wisdom of this website would be greatly appreciated.
HELP!!!!
