Unfortunately this was a project I started,used to be a mechanic so I said I'd try and create a model or the majority by memory,was not too fussed about dimensions,just wanted to see if I could get it visually right,had only started it and was about to do water jackets and oil galleries when we had a power cut and all I had was a jpeg my brother had taken,these things happen,but now the save button is my best friend,theirs a lesson in everything!!!
