But the metal was very hard to function, along with a prodigious amount of labor was involved in grinding and polishing the curve. To facilitate the function, the comparatively thin disks had been cast to the approximate curve, the backs also being curved to give uniform thickness and equalization of temperature effects. Grinding was completed on convex iron tools of similar radius, utilizing emery, and in some cases sand. Polishing was done on a pitch lap, with rouge. Producers commonly devised their very own machines to do the function of grinding and polishing. Except where the utmost perfection was imperative, figuring appears to have consisted for essentially the most component of a final brief variation of the stroke, in an unguided try to concentrate the polishing at the center.
