Weinbach is a member of the Petrof family. You might want to call Geneva International (the distributor) in Wheeling IL and describe the spring to them. Their phone numbers are (800) 533 2388 and (847) 520 9970. Sorry, I don't remember the official name of that part, but I have had to replace a couple of them about 5 years ago. If this is the 3rd time the spring has broken, be sure to check the alignment of the whole trapwork assembly from the brackets screwed into the piano's floor on up. About 5 out of 10 were so misaligned that the pedals barely worked. The sideways motion of some of the components (that should have been moving straight up and down) made me think there was considerable stress that shouldn't be there. It wouldn't surprise me if that is why the spring you mentioned broke so many times. I have to confess, my rebuilding-surgery skills are perhaps minimal at best and the corrective surgery I did was based on blunt see-where-it-wants-to-go technology. In other words, I would detach the pivoting blocks (for the horizontal arm that ran between the pedal and the vertical dowel) and the spring under the arm, and just play with the pieces to see where they worked most comfortably without interfering with anything stationary (plate struts, the assembly to the soft pedal, etc.). Then I would fasten everything down in this "comfort zone," check my work, and wait for the complaints to come in. So far so good ... and I have yet to be called back because something broke again. Good luck. Z!

I had never heard of Weinbach. In any case, the support for the sustain dowel was different from the two methods I am familiar with. The bottom of the dowel had a pin in it, pretty standard. But to hold the top in position under the liftrod tongue, a small piece made of spring steel and a little less than 4" long was attached to the keybed at one end and the dowel at the other. This piece had broken at a screw hole in the keybed end. The fix is easy. Get a new spring and screw it in. It's finding the spring that may be time consuming and therefore expensive. Three questions: What is the official name of this part? What is the most efficient way to obtain this part? Thirdly, the client says this is the third time this part has broken, and the piano is only six years old. Has anyone else run into this problem, and has any kind of alteration been successfully attempted? Thanks, Clyde Hollinger
