Abstract
A method for using a positioning apparatus having a cylindrical shaft including a retaining shaft, an expansion shaft, and a frustoconical transition shaft extending therebetween. The expansion shaft has a recess sized to receive a flange radially extending outward on an elongated member. The shaft is configured to be received within a housing having a passageway extending therethrough. The passageway is defined by an interior surface which includes a cylindrical first surface positioned at the top of the housing. The first surface has an inner diameter equal to the outer diameter of the split ring. The interior surface also includes a frustoconical constriction surface positioned at the bottom end of the housing. The housing raises and lowers relative to the shaft for positioning the split ring onto the elongated body under the force of a weight.
