I went and looked at mine. The center horizontal beam is parallel and almost touching the front of the cabinet heading off to the left side. It is connected to both the center pedal and the left pedal with little threaded rods. There are two wooden blocks that engage pins on each pedal to form a hinge. There is a coil spring that holds the pedal up. There was some felt in there to prevent metal to metal contact. The one thing I never solved during refinishing was how to get the pedals out without taking off the bottom of the piano. Gerald
