Torque wrench vs my own arm, I finally learned my lesson

Last month I was putting a nose gear wheel back on a Cessna 172 and figured I could skip the torque wrench for the last few bolts. Just felt it out, you know, like I'd done for years. Turned out I over-torqued one stud and it snapped clean off during a post-maintenance run-up. New stud, new nut, and a solid hour of explaining to the lead mechanic why I trusted my arm over a $150 Snap-on. Anyone else ever get humbled by skipping the calibrated tool?

Tell me this, did you actually FEEL it give before it snapped, or was it just this sudden pop that made your stomach drop? Because I've got a theory that most of us who do this have that moment where we KNOW we pushed it too far, but we're already committed so we just keep going. Also, what did the lead mechanic say when you had to walk over and confess? I'm guessing it wasn't a gentle reminder about your safety margins. Mine gave me the whole "that's why we buy the tool" speech while handing me a broom to clean up my mess. It's a funny thing, pride over precision. It always costs way more than the calibration fee.
