I'd been using a 3/8 drive on the same set of engine mount bolts for a year before a new guy asked why I didn't just use the 1/2 inch.

The torque wrench I'd been borrowing from the hangar next door was actually set for inch-pounds, not foot-pounds, which I only realized after his question made me double-check the calibration sheet.

That calibration sheet is the first thing I check now.

Ugh, @hannah320, same here.

My buddy learned that the hard way last month. He skipped the sheet, printed a whole batch of parts, and every single one was off by like two millimeters. Total waste of filament and a whole weekend.

And that calibration sheet is honestly the most important piece of paper in the whole process. You'd think after the first time you mess up, you'd learn, but I've seen guys skip it over and over again. It's like they think they're too good or too fast to bother with it. But one wrong setting can cost you hours of rework and a bunch of wasted material. I always tape mine right to the tool I'm using so I can't miss it.
