Pro tip: A retired guy at the diner told me he used to check sand moisture by feel.

Ran into Frank, who worked at the old Republic Foundry until it closed in '98, while grabbing coffee this morning. He said his foreman would grab a handful of molding sand, squeeze it, and know instantly if it was right, no fancy meters. Made me wonder how much we rely on gear now versus just knowing the material. Anyone still use the hand test for green sand, or is that skill pretty much gone?

That old school method sounds cool, but it's not really practical anymore. Modern foundries need consistent numbers, not just a guy's gut feeling about moisture. The gear we use now catches problems a hand test would miss every single time. Those skills are gone because the better tools made them obsolete.

Sure, the gear is better, but now we just argue about whose spreadsheet is right.

You're right about the gut feeling part. The real loss is the feedback loop. A guy feeling the sand knew right away if his mix was off and could fix it. Now a sensor flags a problem, but the operator might not understand why it happened. We get the number, but not the instinct for how temperature or batch age actually changes things on the floor. The tool gives an answer without teaching the cause.
