Old timer in the Toledo plant told me to listen to the metal, not the gauge.
We had a pour for a big gear blank, maybe 800 pounds, and the pyrometer was reading fine. This guy, Frank, who ran the cupola for 30 years, put his hand near the stream and just shook his head. He said, 'The color's lazy, it's too orange. Your number is lying.' We held it back for another five minutes and the difference in the grain structure after the shakeout was night and day. How many of you still trust your eyes over the digital readout?

That's not a gauge, it's a pyrometer.

Okay calling it a pyrometer makes way more sense. I've been calling that thing in my oven a temperature gauge for years. My wife asks how hot it is and I'm like "the gauge says 350" like some kind of pioneer. Next I'll be calling the fridge an ice box.

My friend called his thermostat a heat dial.
