After mastering the setting-out in connection with the last hopper the reader should find no trouble with this, the methods being identical. It will be noticed (Fig. 108) that some of the lengths are marked down one side of the cone, and some down the other. The two halves of the pattern being the same, lines will be used twice over, as seen by the numbers. On account of the hopper being on one side of the pipe, the hole in the plate will be egg-shaped, as drawn.
