Some folks are asserting that the rod can push the collective damper levers and their springs enough to cause leakage unless you have a auxiliary damper lever. I am just saying, "No way!". On a properly designed and adjusted damper system this just isn't going to happen. See my Young Chang reference in my post to Ron. As for your misadjusted spoon illustration, I unable to see your point with regards to the rod? >It's important that the rod not be in contact with any dampers in its off >position. Some meet that without the dummy damper. If it doesn't you need >it. That criteria is customarily taken care of by introducing lost motion in the sustain pedal, not by having a dummy damper. Please keep in mind, I am referring to properly designed and adjusted damper systems, not ones out of whack or in disrepair.
