Tom: Feel the spring for a crack. That would be my first guess. dp David M. Porritt, RPT dporritt at smu.edu<mailto:dporritt at smu.edu> From: pianotech-bounces at ptg.org [mailto:pianotech-bounces at ptg.org] On Behalf Of Tom Sivak Sent: Monday, August 03, 2009 4:30 PM To: pianotech Subject: [pianotech] sustain pedal problem List I'm sure many of you have dealt with this problem, on Wurlitzers and other spinets, and I seek your advice. The problem: the sustain pedal does not lift the dampers due to the trap lever not pivoting very well. The trap lever on this piano pivots on a "C" shaped spring, which is anchored to the floor of the piano and to the lever. In a perfect world, it would rock back and forth on this spring, the pedal pulling it down on one end, and the other end going up to raise the damper lift rod. However, the lever moves laterally when the pedal is depressed, and there is very little damper lift. I've seen loose anchoring screws cause the problem, and have tightened or shimmed the holes and tightened them. But the screws are tight on this one. It just seems to lean to the side instead of rock. Any suggestions on a fix? New spring, maybe? Tom Sivak Chicago -------------- next part -------------- An HTML attachment was scrubbed...
