If one wanted to model an older facility using a grind stone, here’s how they might have made the business end of it, starting with quarrying:

Then shaping:

WATCH Stone Masons Create a Millstone by Hand in 1966!

Then installing, in a saw-making factory.

Installing a Massive Hand Cut Grindstone in 1971
