Abstract
A method of forming a stem and assembling a snap ring in a groove in the stem without expansion of the snap ring. A stem blank is formed having a reduced diameter extension. A snap ring is slid over the extension without expansion of the snap ring and is positioned against a lower support surface. An orbitally rotating punch is inserted at an angle into the top end of the extension thereby deforming the top end and forming a continuous, tear free collar which forms an upper wall of a groove defined between the collar and the support surface. The snap ring lies within the groove and is free to move from the support surface towards the collar.
