I have a degree as a metalworker, with specalisation degrees in silicone lathes and CNC machines and a degree as a car mechanic.
At the moment i'm following another specalisation course for repairing body work (Which sadly enough is a dying breed of workers as cars use more and more plastic lately.)
In the future i'm also looking at doing an electricians course and very likely to look into aero mechanics for smaller private airplanes.
