To facilitate the function, the comparatively thin disks had been cast to the approximate curve, the backs also becoming curved to give uniform thickness and equalization of temperature effects. Grinding was carried out on convex iron tools of comparable radius, employing emery, and from time to time sand. Polishing was done on a pitch lap, with rouge. Producers often devised their own machines to do the work of grinding and polishing. Except where the utmost perfection was imperative, figuring appears to have consisted for the most part of a final brief variation of the stroke, in an unguided try to concentrate the polishing at the center.
