Just read an old Otis manual that changed how I look at governor ropes
I was cleaning out a supply room at a hospital job in Tacoma and found a 1972 service bulletin. It said a worn governor rope can lose up to 40% of its strength before it looks bad to the eye. I always did a visual check, but now I'm using my tension gauge every single time. Has anyone else found a rule of thumb that's totally different from what you were taught?

Man, that's wild. I used to eyeball stuff all the time too, like a real genius. My old boss caught me doing a visual check on a pipe thread once and just shook his head. He made me use the gauge and sure enough, it was totally wrong. Now I trust the tools over my own two eyes any day, lol. That bulletin probably saved someone from a real bad day.

That "looks bad to the eye" part is so true. I had a rope pass a visual once but my gauge showed it was way out of spec. Now I just trust the numbers, not my eyes.

Yeah, trusting the gauge over your eyes is the only way. I've seen guys try to judge wire rope by how it "feels" when you run a rag over it. The rag will catch on a broken strand you can't even see. The gauge finds the flat spots and the thin spots every time. Your eyes just get you comfortable with something that's already failed.
