Got called out on my hoistway door gap checks last year
Tbh, an inspector in Cincinnati watched me do a quick check with my fingers and said, 'You know that's not repeatable, right? You need a gauge.' He was right. I bought a basic feeler gauge set the next day. Now I log the exact measurement for every door, not just a 'feels fine'. Has anyone else had a simple tool change make their work way more solid?
I grabbed the basic analog gauge from the hardware store, the one with the tiny numbers. My check time is still about twenty minutes because I have to squint at it and guess three times. Honestly, the only thing getting cut in half here is my confidence in my own eyesight.
My uncle was the same way with his old tire gauge. He'd spend forever checking, then get a different reading at the gas station. He finally got one of those digital ones with the backlight and said it was like going from a flip phone to a smartphone.
Remember thinking a ruler was a high-tech measuring tool. I used to eyeball everything until I messed up a simple shelf install three times. Getting the right tool just stops the guesswork.
