Cast Wheel Section
One arc of a rim. Four make a flywheel's rim, eight the large wheel's.
One Sand Casting Cell pour with the wheel-section pattern makes one Cast Wheel Section, 600 units, the same cast charge as Cast Shell, so telling the two apart at a glance is a matter of the mold they came from, not the metal. A small flywheel's rim takes 2400 units of cast iron across its four sections, the large wheel's 4800 across eight.
