A method and apparatus are provided for extending the life of spinners by means of reinforcement which comprises a plurality of arms secured to the bottom wall of a spinner either individually or via an annular plate from which the arms extend. The reinforcement applies a radially inward force on a flange extending from the top or center of an outer sidewall of the spinner. The arms exert the radial force as the result of offset cams, due to a prestressed condition which is released after the reinforcement is installed in a spinner or otherwise. If the spinner includes both a center flange and an upper flange, the reinforcement may be installed to engage the center flange with gussets interconnecting the center flange and the upper flange at least at locations corresponding to the reinforcement to thereby provide reinforcement for both flanges. If the reinforcement is formed integrally as an annular plate with arms extending therefrom, the flange to be directly reinforced can be notched to receive the reinforcement by a bayonet coupling motion.
