An analysis of these motions, by right and left hands, is given in the table on [page 120]. It illustrates the important point that the right hand was busy all the time, but for a considerable part of the time the left was doing nothing but holding the piece.
On pages [118] and [119] are shown drawings of the old and the new assembly methods. Likewise, the lower table on [page 120] analyzes, by right and left hands, the motions required by the new method. Note first that fewer elements—17 as against 26—are required. And note that both hands are productively employed with shorter distances to travel for stock and with decreased effort.
