The boy mechanic, book 3 : 800 things for boys to do

A sprawling workshop of imagination awaits anyone who loves to tinker, with detailed, step‑by‑step plans for everything from a miniature electric locomotive and a model submarine to a sturdy bike‑powered parcel carrier. The book blends clear engineering drawings with practical advice, guiding young builders through the basics of framing, gearing, and wiring while encouraging them to add personal flourishes as their skills grow. Over 800 projects are illustrated with more than 800 drawings, offering a picture‑rich roadmap that turns a garage or kitchen table into a mini factory.

Beyond the big‑ticket builds, the guide is packed with smaller, instantly rewarding projects such as hammocks, a diving tower, and an ice‑yacht model, each designed to spark curiosity and develop problem‑solving confidence. The language stays friendly and straightforward, assuming only a modest familiarity with tools and inviting readers to enlist a helper when needed. By the end of the first act, a budding mechanic will have a sturdy motor‑car chassis under his hands and a sense of what’s possible when imagination meets brass and wood.
