A retired caster in Detroit gave me one piece of advice that saved a pour
He was watching me struggle with a stubborn sand mold for a gear blank last fall, and he just said, 'Kid, your flask is colder than the metal.' I'd been rushing and didn't let the mold warm up enough in the drying oven. Let it sit for another twenty minutes and the fill was perfect. What's the best simple tip you've gotten from an old hand on the floor?

Funny how the simplest things get overlooked. Always thought a hot pour was the only thing that mattered, but that mold temp tip was a game changer.

How many times do we gotta learn the hard way that rushing just makes more work? That old guy probably saved you a whole day of grinding out a bad casting, lol. It's always the stuff that seems too obvious to mention that bites you. My version of that was learning to just walk away for five minutes when a weld starts looking like a spider took a crap on it. Letting it cool down a bit fixes half the problems before you even pick the grinder back up.
