4). The sand is built up in layers until the drag is filled. After filling the drag the bottom (which is the top at this point) is leveled off and the mold is vented. A wire is poked into the sand to make holes that will allow the air and steam in the mold to escape when the metal is poured into the mold (Figure 5). Figure 4 Ramming the Sand
