Screw-Thread Cutting by the Master-Screw Method since 1480

A fascinating journey into the origins of screw‑thread cutting begins with the rare 1483 lathe depicted in medieval manuscripts, followed by a surviving traverse‑spindle instrument from the late 17th or early 18th century. The work traces how these early, purpose‑built machines gradually gave way to the versatile tools that dominate modern manufacturing. By examining sketches, surviving artifacts, and contemporary descriptions, the narrative reveals the ingenuity of early engineers who distilled complex motion into simple, effective mechanisms.

The author then follows the evolution of these devices through a detailed survey of patents up to the 1930s, showing how each innovation contributed to the burgeoning machine‑tool industry. Readers learn how design choices—such as the relationship between slides and spindles—reflected emerging understandings of precision and natural law. This study offers a clear, engaging look at how a specialized craft grew into a cornerstone of industrial technology, making the history of screw‑thread cutting both accessible and compelling.
