I do CNC lathe. I could run it with the door open but don’t due to coolant. It shouldn’t run with the door open but it does run like that. Safety interlock is long gone. I roll my sleeves back on my flannel jacket and button the cuffs. I sweat a lot and the breeze that brings me fresher air makes me get cold easily.

I have seen the Tool Time episode where Tim The Toolman Taylor has his shirt ripped off by a lathe and am very aware of the danger every day. The green button doesn’t get pushed until doors are closed.
