The exact technical term you are looking for is "turning something on a fucking lathe".

Bravo Mr G! Brevity is all! ;)

But inside it's not turning it's boring.:p:

Ever seen anyone bore a bowl on a lathe?

I'm a machinist, I don't make bowls. Neither did Ruby.

Seeking some respite from the endless hedonism that is my lot in life, I turned to the book review section of this morning's Sunday Times.

Behemoth: A History of the Factory and the Making of the Modern World by Joshua B Freeman was featured and illustrated by this image.

Attachment 63541
On her metal: a machinist at an aircraft factory, 1942

Very much in FWIW territory I know, but I've included it as, unlike the painting, it probably isn't open to interpretation.

Over to you, Dwellars.

That was taken by Alfred Palmer in October of '42 at Douglas in Long Beach.
He took several pictures almost the same but slightly different elevations.
Fascinating specialized boring machine.
I HATE PINTEREST.
