Compilation Jan Ridders model engines 2002 2014

This is a compilation of about 40 small model engines that I designed and made during the last 12 years of my retirement: Stirling engines, Flame-Eaters, Internal Combustion engines, some special devices/tools and presents for my grandchildren. Sorry for the rather poor piano music, but I had to learn that myself during the last 3 years in the evening hours; you can switch off the sound of course if it is too bad for your ears.
