In this video I debunk the myth that the correct way to make splice joints in chassis members is with an inclined or Z cut. These are scarf joints which have been used for centuries in timber structures but have no place in welded steel structures.
I also address the supposed regulatory requirements about this which apply in certain parts of the world.
Of necessity this is a technical video although I have tried to make the concepts understandable to non-engineers.
This is a re-posted video with the new content appearing at 16.30.
This video builds on ideas introduced in my earlier video on chassis repairs (please watch this first)
