Craft work and a new rifle
John Hancock Hall was born in Portland, Maine, in 1781. He worked in his fatherโs tannery before establishing himself in woodworking, machining and boatbuilding. His interests turned toward firearms, and in 1811 he patented a breechloading rifle. He married Statira Preble in 1813. The familyโs later move to Harpers Ferry accompanied a change in scale: a private makerโs design became the subject of a federal contract and a specialised production establishment.
Building a workshop around a principle
In 1819 Hall contracted to produce one thousand rifles and occupied a former armory sawmill beside the Shenandoah. He spent years developing machinery to reproduce parts consistently. His equipment included cutting, drilling and stock-making machines, while gauges helped maintain the intended dimensions. In a December 1822 letter he claimed to have established successful methods. That statement records his own assessment; later official inquiries and production evidence are important for evaluating how the workshop actually performed.
