Welcome to my page on the Web

Here's what I did today in terms of engine construction. Since I am neither a web designer or writer,
the images are described only with technical details of the engines.


After many Zyl.Kopf constructions and reconstructions of the 125 Four is now the first construction of a complete four-cylinder engine.



Had a lot of fun with design and construction.
