I have heard that the Germans succeeded in machining a wire
that was so microscopic thin that it was invisable to the naked
eye. Wanting to SHOW OFF their technology, the Germans sent
this wire to Switzerland where a hole was neatly bored thru it
from end to end, and sent back to Germany.
So GET WITH IT you two because ,00004" is exactly the same
as 1/1000 of a mm or I am not reading my K&E slide-rule right.

Leica Solms bought some years ago from Deckel (the same people that made
Prontor shutters) NC equipment that machines with 1/1.000 mm tolerance.
