I did some machining back in the day, before they had computer controls. I remember manufacturing aircraft parts by hand. In those days, Starett was a first class outfit. We worked to tolerances of .001 and less. Everything was done by eye and hand, mills, grinding, lathes, all sorts of machine tool operations. What you are describing sounds like a bad dream. In my day, the first thing you did was learn to file, using an aluminum block. It had to be straight and true. My father told me that in Germany, they did the same, but they used a 3 inch cube of steel. He said it was not uncommon for the blocks to be reduced by half an inch by the time the student produced a cube acceptable to their teachers.
