What kind of books were you trying to press with it?

Wait, they were trying to save money by doing their own wiring? That's insane. You can't put a price on not burning your house down. A quick chat is the absolute least you can do for someone that reckless.

Got a different take on that. Seen a few old Mazaks run that long, but they're usually held together with baling wire and prayers by that point. The real story is the mountain of cash spent on parts and downtime to keep it limping along.
