Sewing machine cabinet vibration dampening using rubber magnets

In a sewing machine cabinet having a base, a sewing machine support surface fastened to the base for supporting a sewing machine thereon, said sewing machine having a bed supporting a work surface, a convertible work surface moveable from a lowered position wherein said convertible work surface forms an extension of said sewing machine support surface to a raised position wherein said convertible work surface forms an extension of the work surface of the sewing machine bed, and at least one articulated ferrous support hinge for supporting said convertible work surface in said lowered position and in said raised position, a vibration dampening member for dampening vibration associated with said at least one articulated support hinge for reducing the transmission of vibration between said support surface and said convertible work surface, said vibration dampening member comprising a material having a resilient surface which exhibits magnetic properties, whereby a ferrous hinge placed in the vicinity thereof will be attracted to said vibration dampening member and precluded from vibrating by said resilient surface.
