I think the Dave Gingerly Series is an amazing concept. Here's the deal. As you progress through the seven books, you build an entire machine shop from scraps and commonly found items. You start with casting intitial parts in a homemade charcoal foundry. Once you have completed a given tool you then use it to build the next tool. I want to take a sabbatical just to experience building my own machine shop. (Sponsorship offers will be considered.)
Believe me, this just scratches the surface of the books they offer. Almost all are mechanically-oriented.
