A one-page question-and-answer column by Mary M. Atwater on converting a four-harness loom to eight harnesses. She describes extending the uprights and hanging extra harnesses from rollers, which suits only balanced weaves, and the better option of a top mounting with jacks or levers (single or double sets). She also explains how the warp balance of a jack loom differs from that of a counterbalanced loom, and the lamms and treadles needed for eight-harness weaving. Five diagrams illustrate the mountings and warp balance.
