A practical trade manual that presents step-by-step methods for laying out, cutting, and assembling stairs and handrails. It begins with elementary geometric problems and stretch-outs used to form curves and easings, then explains how to transfer site dimensions onto rods, set out risers, goings, strings, newels, landings and winders, and apply the steel square for accurate profiles. Plates and worked examples illustrate full-size layouts, recommendations for rise-and-run proportions, and a tested square-section and falling-line approach to handrailing, with detailed workshop techniques for cutting, fitting and joining components.
