So a torque wrench is just another way of going wrong with confidence, right. That's comforting. I'll just go on using my calibrated arm that has been trained on gazillions of broken fasteners, except on head bolts, main bolts and rod bolts, where I'll use a torque wrench and go wrong with more confidence. It's like my Chevy that has a torque spec for an eccentric camber setting sleeve - That could be from Firesign Theatre - "Micky Way......."
