This book contains a design for belt-fed red circuit production that outputs 26.67 circuits per second, or a full red belt. It also includes a blueprint the same design repeated twice side-by-side, with the second column flipped horizontally so that the combined factory is lane-balanced. Additionally, it includes the doubled-up design repeated three times so that the combined design consumes six blue belts each of plastic and green circuits, consumes five blue belts of copper plates, and produces exactly four blue belts of red circuits, which demonstrates how the design can be tiled.
