"The Turner's Companion" by Anonymous is an old-fashioned instructional book about the craft of turning, a skill used to shape materials like wood and ivory with a lathe, written during the late 1800s. The book walks readers through different turning methods, from simple to complex, including how to make circles that share a center, oval shapes, and shapes that are off-center. It explains the uses of different tools and attachments, like specialized cutting tools, drills, and rests, while also featuring designs and step-by-step instructions for making them. By presenting the subject matter in an easy-to-grasp way, this manual seeks to encourage newcomers, especially women, to explore the artistic and useful possibilities of this trade, highlighting its aesthetic appeal and practical benefits.
