That looks like some beautiful engineering. Could we see some more photos of the rest of the car?

Sometimes see "belt and braces" safety brackets on similar lines. However if the arm fails at the shoulder instead of at the more usual radius may be of limited assistance.

Just as a matter of interest, I know it's serious if it happens, but, how many people have actually had a steering arm failure?

True, but its a stronger Big 7 arm which has also been been crack tested and polished. The fabrication adds some strength but its main purpose it to facilitate canging the steering ratio.

My pic seem to be too many mb's. I'll try and post some more if I can work out how to modify them!
Another go.
