The construction plan
The construction plan consists of six format DIN A3 sheets with a presentation of the individual parts as well as two sheets in the same format with the views i.e. cross-section of the complete engines. In addition there is are several pages of specifications containing part lists of all parts. There are also suppliers addresses listed for e.g. ball bearings, cogwheels or valve springs.
The plan is very precise and shows all parts in a comprehensible form.
Many feedbacks including photos of engines constructed by customers confirm that they have been successfully reproduced.
However, a lathe and milling machine is necessary for the manufacture.
