Hello and greetings from Devon, UK
I found this forum whilst searching for a solution to a problem.
I believe the search term I used in Google was "mechanical design".
I will explain the problem briefly and if it is allowed to be discussed by the Administrator I will elaborate in the appropriate section of the forum.
First a little background.
I'm a qualified mechanic and autoelectrician who has worked for Peugeot, Ford, Renault, Jaguar, BMW and the AA.
Holy Grail of Mechanical Design?
