With 20 fascinating projects, this title challenges even the most accomplished turners. Chapters focus on three secrets of turning--marking with precise mathematical formulae, constructing purpose-built jigs and chucks, and making and adapting special turning tools--while also discussing safety procedures and inexpensive sources for readily available wood. The projects range from a delightful old-fashioned whistling top and a yo-yo to the incredible turned trickery of cubes in spheres, stars in cubes, and interlocking spheres.
