I seem to recall flipping through a book, and I think it was this one. I was suspicious, so I looked at the reviews carefully and found several that claim there is nothing about how to make them:
So far i have only read about a 1/4 of the way through it, but as a machinist/welder by trade, i was expecting a little more detail on the plans and directions...
...I wouldn't consider this a "do it yourself guide" but, an industrious builder/ engineer could get a kick out of attempting these fun old ideas. Not overly useful but thought provoking.
The problem is that our culture has become obsessed with "what" instead of "how", because that is the focus of our educational system. We produce kids who have opinions of Thomas Edison but have no idea how a lightbulb works.
