Spent the last work week getting trained on drills. When I was an oiler I spent a lot of time on and around drills and they always looked really complicated- all these knobs and buttons and levers and stuff. Turns out, not so much. Pretty simple. To be fair, though, the newish drills we have now are all computerized and GPSatized and pretty much fool-proof.  I will say that it takes a special kind of person to be a good drill operator- a person who is comfortable with doing not very much for prolonged periods of time. A person who prefers quiet contemplation to constant motion and action. A lazy person, in other words. I tell you now, I am that person.
