Day 8: Turner's Cube

I'm trying to upload a Thing-a-day this February.
makerblock.com/2011/02/makerblock-thing-a-day/

A Turner's Cube is a machined curiosity that used to be shown to a novice machinist. Their task was to (a) figure out how to re-create the object and (b) operate machinery with enough skill to re-create it.
