Only Edition. A pastor at Altburg, the author came to turning at the suggestion of his physician, who was concerned about the author’s sedentary lifestyle. By 1775, Bohnenberger had mastered simple turning. Then he encountered the Schneckenspindel, an early version of an eccentric chuck. This specialized cutting tool offsets a workpiece from the central axis of the spindle allowing the turner to cut multi-axis, off-center or spiraled shapes. He immediately began designing and manufacturing his own spindles of varying sizes. Decades of practical knowledge ground his discussion of the construction of the accessories and the production of simple and compound designs — shells, swirls, spiral columns, rosettes, pinwheels, etc. All these are illustrated. One copy in U.S. libraries. In good condition (a few smudges on three leaves and three plates, two small holes in blank areas of two plates).
