A few years ago I had to work on a Okuma turret lathe that the operator was setting up to bore a Carbon Disk Brake for a Boeing 747 and the operator miss placed a decimal point and took a 1.000" cut instead of a .1000 cut and the brake self destructed lucky the operator wasn't standing in front of the machine but as a maintenance mechanic my helper and I had to replace a sheared 3/8" allen head cap screw and a 3/8 tapered aligning pin on a machine that's almost indestructible.
