I did study DC machines in college; there was a full year on large machinery, primarily because the department head taught the course. There were five of us in the class; it was Greek to them but I rather enjoyed it since I had already spent two summers in the repair shop and understood what was going on without having to read books. It was the math part that was Greek to me. Still is, but I didn't have to design them, just repair them.
We had an undercutting lathe in the shop but I never saw it in use the whole time I was there. Far too much trouble to set it up. We used old hacksaw blades, with one end ground into a hook. You pull it back toward you, away from the windings.
