How was it made then?
The circle is made up of eight box-section segments, each curved a little and tapering in profile, so the circle is thicker on one side than the other. From this circle five arms shoot out – a bit like the sparks flying out of a spinning Catherine Wheel – to which the cars, either upside down or vertical, are attached.
Getting the cars on and off is the tricky bit. Each car has to be craned into and out of position, with the top first and then pivoting from the top, then swinging upside down to get the correct angle so the wheels slot into their positions.
And exactly how are these priceless F1 beauties secured?
Would you believe straps around the wheels? It’s true. There are safety wires as well, just in case.
The finished article is very smooth and white…
So it should be. Each piece of sheet steel was laser-cut for precision (and to reduce wastage) before being welded into the box-section segments, which were then shot blasted, holes filled, sanded down, primed and painted. It is very smooth and white.
And the whole lot just sits there on the grass?
There’s a bit more to it than that. The heaviest segment of the circle, at 16 tonnes, is the base piece which is bolted to a frame set in foundations deep under the immaculate Goodwood grass. “This piece basically holds everything up,” says Steve Fallick. The circle’s torsional rigidity isn’t complete though until the top “keystone” segment is put in place.
Anything different in getting it up this year?
For the first time, no welding was needed on site to put it up. All the sections were designed to bolt together which made it a lot quicker to assemble – and will make it quicker to take down after the Festival.
