This beautifully manufactured toroid was custom made in Switzerland by Christos Galanis.
NB: (Although I am kindly allowed to use this toroid it belongs to a fellow coiler - P Strauss)

Overall sizes:
Main diameter: 49.4 inches (125.5cm)
Minor diameter: 11.18 inches (28.4cm)

It consists of 32 segments, each being made from a 'fish-shaped' template. These can be seen in pictures of the manufacturing process, which can be seen Here.  (Note: Prices quoted no longer apply, as 14 years out of date)

Each individual 1mm Aluminium segment then has a rolled edge applied, allowing it to be joined to its neighbour.

Unfortunately the manufacturer was unable to provide shipping, so collection was from Switzerland.
