No tool, no problem - The making of a 2.35mm socket on a lathe

Fabrication d'une douille de 2,35mm sur un tour

[@petermichaelgreen]

It strikes me that 2.35mm is very close to 3/32 inch. Maybe an imperial socket is what was intended.

I'm not sure about what the intention was. It is swiss made so I guess it's supposed to be metric, but the screw heads edges are all very slightly conical, because of the polishing probably. I'm not used to the imperial system at all so I couldn't come up with that idea, 2.35mm was the approximation found out by my micrometer, it was actually about between 2.35 and 2.36. Does imperial sockets of this size exist for sale on any market? I don't think it does even for metric, I've never seen that anywhere, I'd didn't even try to look it up haha.
