the end of a scale and one point of the caliper against a solid surface and
adjusting the other leg to the proper graduation (A, fig 52). The spring caliper
is shown being used to check the inside diameter of a bored hole (B, fig 52).
Figure 53 illustrates the correct and incorrect positioning of the calipers with
relation to the axis of the work. The transfer feature of the caliper is
illustrated in figure 54. Note that the diameter being used is recessed and that
the setting cannot be transferred to a scale directly because the legs must be
collapsed to get them out of the work. The setting must be reproduced after the
dimension from an inside spring caliper.
