If you have always wanted to build a working model from scratch or are fascinated by Stirling engines and want to experiment further, but have been frustrated by lack of any machine tools, then this is the book you have been waiting for; quite simply it is brilliant.
Here Kjeld describes how to build his first engine in some detail, and then how to construct the subsequent five engines, which largely develop from each other, in slightly less detail, but still plenty enough for you to build them.
