There where a few things I learning in high school, one was never leave a chuck key in the chuck, I've seen why when someone start the lathe, luckily no damage or injuries when the key launched across the room (all I heard was "DON'T", lathe starting, key bouncing off the wall across the room follow by the same voice (teachers) cursing out the student).
So I hate pictures that show that.
Lathe looks in good condition.
