The old issues of Popular Mechanics stacked in my Grandmother's basement were water damaged, mouldy, and mostly unreadable, but they contained articles that were detailed and left the reader ready to dive in and begin building.
I was expecting this book to be a compilation of that sort of article. I was disappointed. A better subtitle might have been "An ABRIDGED ABSTRACT OR SYNOPSIS of the Best Projects...et c....
While the articles in this collection SEEM like reprints from Popular Mechanics, they appear to have been severely edited. Very few of the articles contain enough detail to actually guide a "Boy Mechanic" through the construction of the project. The articles are lacking in things like major dimensions, materials lists, and technical drawings. For example, the article on building a model airplane leaves out critical information like outlines of the wing ribs or fuselage formers, wing span, fuselage length, or even scalable three views of the model.
This is a lightweight nostalgia trip for readers who want to laze away an afternoon dreaming about things they might have built in an imaginary childhood. But readers who are actually looking for projects to build with their own budding boy mechanic, this one lacks.
There are some good ideas, but even a Boy Mechanic with substantial training, prior shop experience, and a well equipped workshop would need to devote considerable time to the design process before attempting most of the projects.
