Lathes, drills, shaping machines, milling machines, borers, these are most people's ideas of the engineer's tools. All are used for cutting. There is a wide variety of tools for cutting metal, but they are fundamentally the same. They are all wedges. This group of five programmes will show how good workmanship in cutting metals depends on understanding its fundamental principles. Joining metal makes perhaps a logical sequel to cutting it, and later programmes will show gas and electric welding.
