My stubborn trust in manual door gap checks just got busted

I used to swear by my feeler gauge and a good eye for setting elevator door gaps, thinking anything else was overkill. Last month, I was troubleshooting a persistent noise complaint in a mid-rise apartment building. We'd adjusted the doors three times by hand, but the grinding sound kept coming back. A younger mechanic on site insisted we try his digital gap meter. I laughed it off at first, calling it unnecessary. He showed me the readout: one side was a full millimeter tighter than the other, something we totally missed. After fixing it to the exact spec, the noise vanished and hasn't returned. I had to eat my words and order one of those meters the next day. It turns out my old methods weren't as perfect as I thought.

Feel that. Tech just spots the tiny stuff our hands and eyes filter out. Had a similar thing with laser levels versus my old chalk line, numbers don't lie. Swallowing your pride for a quiet door is a solid trade.

Man, that's spot on. My friend Mike was the same with his bike repairs, always eyeballing chain tension. He laughed at my tension gauge until his chain snapped during a race. Had to walk his bike back, lost his place. Now he checks it with the tool every time. Pride costs more than a simple meter sometimes.
