Blacksmithing - Small Farmer's Journal
Modern farm machinery is largely of iron and steel construction, making an equipment of metal working tools necessary if satisfactory repairs are to be made. Forging operations consist of bending, upsetting, drawing out, welding, punching, drilling, riveting, thread-cutting, hardening, tempering, and annealing. Heat makes iron soft and ductile. Practically all forging operations on iron can be done more rapidly when it is at a high heat. Steel will not stand as high a temperature.
