Fig. 111 shows the method of striking out a pattern for a circular-tapered connecting pipe which joins together two lines of parallel piping. The lengths of lines on the pattern are run around from the elevation as in the former cases, the same plan of lettering and numbering being followed. No laps or allowances of any kind are put on the pattern, as these can be arranged to suit the particular job in hand. The holes in the pipes are not shown set out, as these can be obtained by the method explained in connection with Fig. 107.
