Abstract

A method of forming a gear comprising gripping a blank (10) to be spun formed in a spin forming machine, spin forming a gear having helical teeth disposed on an inner surface, and ejecting the gear (20) by simultaneous extension and rotation of an ejector member (108) and thereby rotation of the gear (20) being ejected.
