Turning a segmented torus, by Kyle Toth. This is made from 2,340 segments.

Commenters point out some long-sleeve turning here, and a bit of sketchy drilling around 6:35. Nevertheless, a great piece, and these toruses sell for over $3,000.

In this followup video, Kyle explains his techniques for cutting an estimated 70,000+ segmented pieces thus far. No sleds, and he uses a pencil mark on a chop saw instead of a stop block.
