Hot take: I thought my old way of rolling tubes was fine until a job in Omaha showed me a better way.
For years, I'd just eyeball the gap and tack it, which led to a lot of rework on the big boiler at the Omaha plant last fall. The foreman there made me use a feeler gauge for every single tube, set at 0.040 inches exactly. It added maybe two minutes per joint, but we had zero leaks on the hydro test. Who else has a simple step they added that saved a ton of headache later?

Wait, your old foreman would laugh at using a feeler gauge? That's wild. My first boss would fire a guy for not checking the gap. I saw a guy eyeball a header joint once, and it blew a seam in the hydro. We lost a whole day of work. That laugh costs money.

Oh sure, let's just add two minutes to every joint, what's the big deal. Next you'll tell me I should actually measure my cuts instead of using the "that looks about right" method. My old foreman would have laughed me off the site for pulling out a feeler gauge, but then again, we also spent half our Friday afternoons chasing leaks. Maybe there's a lesson in that.
