For finishing plane surfaces the flatter shown in [Fig. 2852] is employed, w representing the work. For inside surfaces the flatter requires to be offset, as in [Fig. 2853], in which l represents a link whose face a may be flattened by the flatter f. There is a tendency in this case for the flatter to tip or cant; and to avoid this and regulate the flatter upon the work, a side foot is sometimes added, as at a in [Fig. 2854].
Swages are shaped according to the kind of work they are to be used for.
