Talking to a 30 year veteran changed how I see torque specs

I had a coffee break with Gene last week, the old guy who's been turning wrenches since the 80s. He told me "the book numbers are a starting point, not the gospel" and showed me a corroded bolt hole he found on a 737 where the spec would've just stripped it. It hit different because I've been so strict about following the manual to the letter, but he's got 30 years of knowing when to back off a few foot-pounds. Has anyone else run into a situation where trusting the manual cost you more than trusting your hands?

the book numbers are a starting point" really stuck with me too. I used to be the guy who'd torque everything to the exact spec no matter what, but after snapping a bolt on an old frame I started backing off when things didn't feel right. Now I treat the manual as my guide but let my hands have the final say.

the book numbers are a starting point" yeah and my ex-wife said the wedding vows were a starting point too... I've definitely had moments where following the spec to the exact letter left me with a stripped thread and a lot of bad words. Sometimes your fingers know before the torque wrench does.

Man, that ex-wife comparison is brutal but I get it. Did you notice a specific pattern with the bolts that stripped, like certain thread pitches or metals that just never felt right even when the wrench clicked? I'm curious if the "feel" factor changes depending on whether you're working on aluminum versus steel frames.
