Hot take: I was wrong about using a 3-inch riser sleeve for every single pour at my old shop in Toledo.
Honestly, it took a major blowhole defect on a 500-pound gear blank last month, which my foreman pointed out was from trapped gas that a smaller 2-inch sleeve would have let escape, to make me see I'd been adding cost and risk for no real gain all these years.

That part about adding cost and risk for no real gain really hits home. I used to be a big believer in always using the biggest feeder you could fit, thinking more metal was always safer. Seeing a big, expensive part come out with a major defect because the gas couldn't get out is a brutal way to learn. It forces you to actually look at the job instead of just going with a habit. Sometimes the standard fix is the problem.

Ever notice how that "more is better" mindset messes up cooking, budgets, everything?
