The Library of Work and Play: Working in Metals
"The Library of Work and Play: Working in Metals" by Charles Conrad Sleffel is an instructional manual focused on metalworking, likely written in the early 20th century. This book serves as both a comprehensive guide for beginners and a resource for experienced craftsmen, detailing various techniques and projects involving metals such as copper, brass, and silver. It aims to empower individuals, especially young learners, by making metalworking accessible and enjoyable. The opening of the text introduces the reader to the world of metalworking through a conversation between two boys, John and his friend, who is eager to learn how to create metalwork items. John shares his enthusiasm for crafting objects from copper, emphasizing the enjoyment he derives from the process. He offers to teach his friend, explaining that with the right tools and guidance, anyone can learn to work with metals. This engaging start sets the tone for a practical approach to learning metalwork, laying the groundwork for the detailed instructions and projects that follow throughout the book.

Elementary lathe practice : $b As adapted to the teaching of machine shop practice in technical schools
"Elementary lathe practice : As adapted to the teaching of machine shop…" by T. J. Palmateer is a technical instruction manual written in the early 20th century. Aimed at beginners in technical schools, it teaches foundational engine‑lathe operations and shop practices, focusing on accurate turning, facing, tapering, threading, boring, drilling, reaming, and knurling through tightly designed practical exercises. The book is organized around three progressive exercises. The first covers cutting stock, centering, mounting between centers with a dog, facing, rough and finish turning, tool setting and grinding, speed choices, tailstock adjustment, gauging, and filing to produce a close running fit of a shaft to a collar. The second adds layout to length, recessing, taper turning by offsetting the tailstock, and a comprehensive approach to thread cutting: 60-degree tool geometry and gauging, gearing the lathe for pitch, engaging the split nut, using stops, reversing, and finishing each flank (or using a compound rest), with checks against standard nuts. The third shifts to cast iron and workholding: truing a rough casting in a four‑jaw chuck, rough boring with a flat drill and boring bar, reaming with shell and rose reamers, cutting inside threads, scraping finishes, and setting and machining a 30‑degree seating. A mating piece is drilled, reamed, mounted on a mandrel for external finishing, threaded without relief, its taper fitted and blued, and its boss knurled. Throughout, the instructions emphasize accurate measurement, proper lubricants, controlled feeds and speeds, and safe, efficient setups to produce true, smooth-running parts.
