ABSTRACT:
A method for making replacement grouser bars particularly contoured to fit rock worn grouser shoes from blanks cut from inexpensive sheet metal. The blank has a straight lower edge and a curved upper edge such that the bar is thicker at the ends than in the middle. The straight lower edge is easily double beveled and the blank is reverse forged to obtain a finished grouser bar having a straight upper edge and a curved lower edge, the bar still being thicker at the ends than in the middle.
