Size of the ring (errata corrige) Empty Size of the ring (errata corrige)

After the work done the last week (NI ring adjustement) we have the final shape of the ring. Now is possible to calculate the size of the ring, in the four points diametrically opposite labelled A, B, C, D (clockwise from up).
A = 26.2 mm
B = 33.1 mm
C = 30.4 mm
D = 30.4 mm.

The mean inner diameter is 153 mm (included between 150 mm and 156 mm)
The mean external diameter is 213 mm.
