This is a video of a man carving a cube inside of a cube inside of a cube from a solid metal block, using a lathe. None of the smaller cubes can be removed from the larger ones. Apparently carving cubes inside of cubes is some sort of indicator for how good a lathe turner is at their job. If I had a lathe you know what I would make? "Dildos." You better believe it! Fake wieners as far as the eye can see. Just piles and piles of them everywhere, like you'd imagine the mountain of gold a dragon sits on.
Keep going for the video.
Thanks to JDL, who can carves spheres inside of spheres inside of spheres because he knows black magic AND IT'S MAKING ME JEALOUS.
