But the metal was incredibly tough to function, and a prodigious quantity of labor was involved in grinding and polishing the curve. To facilitate the function, the comparatively thin disks were cast to the approximate curve, the backs also being curved to give uniform thickness and equalization of temperature effects. Grinding was carried out on convex iron tools of comparable radius, working with emery, and often sand. Polishing was carried out on a pitch lap, with rouge. Manufacturers usually devised their very own machines to do the work of grinding and polishing. Except where the utmost perfection was imperative, figuring appears to have consisted for probably the most part of a final brief variation of the stroke, in an unguided attempt to concentrate the polishing at the center.
