Should the post 25 not bein exact axial align'.-

It Will be observed that; the plate `member" 2l renders impossible the mutilation or deformation of the threadsof the terminal postsV during the spinning operationand should burrs be produced during i the; spinning, inner edges-27 of the ribs'24 Which liefadjacent to the Working surfaces ofthe rollerl (Figs 3 and 4)'serve to effectively and positively remove or cut-away the burrs.

The positiveremoval by the edges `27 of anyburrs Which might be produced during Y the spinning Voperationdecreases'the number ofimperfectly spun posts and'eliininat'es the necessity' ofremoving bur-rs Vsubsequent to' the spinning as hereinbefore setV forth. Obviously, the tool'` described gisv very eiliunderstood that the invention is capable of many other applications Which are limited only bythe scope ofthe appended claims.
