A few years ago a local Model T enthusiast lost control of his coupe after hitting a bump in the road and flipped it on its side. He had done the standard safety inspection but there was no question on the form that asked him to check the camber of the front axel. It turns out that the axel had two left side spring perches.
After hearing the story and seeing the car I thought I might undertake the project of writing a Safe-T-Handbook.
This illustration if from the title page of Chapter 5.
The book still needs dozens of illustrations, peer review and editing.
