At the very least, he hoped he could process metal blocks like a carpenter working with wood, using table saws and planers to make various parts for a train.
Although it's much more troublesome than production lines, it's immensely easier than polishing by hand.
So he needed to have a few machines like these.
Otherwise, how could he produce a steam engine?
He polished four discs, spending twelve days, scrapping three, and barely managing to use one.
He believed he was working diligently, so his skills were indeed improving steadily, but there was still a significant gap to his goal.
He often felt that he might have made a mistake somewhere.
A disc with a diameter of fifty centimeters and a thickness of five centimeters, manually polished, with an error of no more than three millimeters.
Is that possible?
He didn't know.
Anyway, he kept trying.
Constantly working from dawn till dusk.
No breaks in between, very little thinking, always keeping his hands busy.
