About to jump in to build this engine later this year. But before deciding to so,Gus has to get some assurance that he is not alone and there must be forum members who done so and succeeded and he can view their threads and ''Monkey see,Monkey do"". Drawing bought on-lineand now being studied carefully as Gus is a "sure to goof" at reading dimensions and fits. Mini lathe and mini mill can just about do it. The Nemett-Lynx Engine did stretch my mini machine-tools and my beginners skill. The Howell V-4 is but a dream to build with my existing machine-tools.
