A concise, practical manual that explains workshop layout, tools, and material choices, then proceeds through step-by-step construction of pipes, sound‑boards, wind‑chests, bellows, trunks, and framing. It covers the mechanical action, stop and pedal mechanisms, voicing and tuning, and arrangements for two‑manual instruments, offering measurements, techniques, and common fixes. Added guidance addresses the design, erection, and care of small or village church organs. The tone prioritizes hands‑on methods, avoiding abstract theory in favor of workable instructions and cautions for artisans, organists, and purchasers seeking to build, maintain, or specify instruments.
