Anyone have a link on how to make it, or other interesting bits?

Thanks for you time

Or how about Bob's spherical project or Abdul's pyramid project?
WTF are you on about???


A turner's cube is a little machinist's show off piece.
It can be made of most any metal and of any size though most are about
2 to 3 inches on a side. The cube is pierced by large holes through
all six sides through which can be seen a second identical but smaller
cube that is too large to be removed throught the holes. Inside this
cube is a third cube. The whole thing is machined from one piece of
metal.

Apprentice machinists used to be shown one, then challenged to make
another without being shown how.


Ah ok!
