Changed my mind about torque wrenches after a chat with an old timer

Always thought buying a cheap click-style torque wrench was fine. Just set it and go, right? Been doing it for years. Then a 30 year A&P guy at ORD saw me torquing a main gear nut. He pulled me aside and said my wrench hadn't clicked right the whole time. He showed me how to verify it against his beam style tool. Turns out mine was off by almost 15 foot pounds. Made me feel like an idiot. Now I only use the calibrated stuff from the shop. Anyone else ever get caught using a bad tool and not know it?

What'd the guy show you that made you realize it was off? I had a similar wakeup call with a harbor freight special that was reading 10 pounds low on lug nuts. Never trusted the cheap ones after that day.

Brought out a calibrated torque wrench and checked ten of my lugs. I was torquing to spec but those made in china wrenches had me 15 pounds under without clicking. Did you ever trust anything from harbor freight again after that?
