Abstract: There is disclosed an improved spindle construction for use in connection with harps of the type having a linkage assembly associated with foot pedals for controlling the action of harp strings. The improved spindle is designed to eliminate friction between the spindles and the action plates which are connected to the two ends of the spindle. The spindle is formed by a cylindrical body portion having a reduced diameter shaft at one end and proportioned to extend into a bore of one of the pair of action plates and to be rotatably retained therein. A bearing sleeve is press-fitted onto the cylindrical body portion at the other end thereof, the sleeve having a chamfered outer peripheral surface which corresponds with a chamfered bore formed in the other one of the pair of action plates into which the sleeve seats.
