The bell and the accompanying coupling bolt provide a means of mass-coupling the plate hitch pin panel to the relatively massive wood rim assembly. In practice this mechanism helps to prevent the hitch pin panel from vibrating sympathetically with, and bleeding energy from, the strings. It raises the mechanical impedance of the plate assembly. The coupling bolt needs to be only tight enough to accomplish this coupling function. Not enough to appreciably affect string bearing. Regards, Del
