Turning and Mechanical Manipulation
Turning and Mechanical Manipulation is a practical manual on ornamental lathe work by John Jacob Holtzapffel, published in 1884 as a digital reprint from a library copy, written for amateur and professional turners. Its pictures are precise line diagrams in plan and elevation, with hatched cross-sections of chucks, spheres and lathe tool positions, useful to designers wanting clean technical drawing with labelled reference points and mechanical geometry.
