Showerthought: We used to set cutterhead speed by feel, not a screen.
I learned on old gear where you'd adjust by vibration and sound. Even with digital controls now, paying attention to those cues can warn you before a jam happens.

Heard about my buddy's old lathe? The whine before it quit was unreal.

On the 1983 Warner & Swasey turret lathe I trained on, the speed dial was just a notch plate. You had to listen for the motor's hum to find the sweet spot. Even with a new Haas with a touchscreen, I catch myself turning the volume up on the shop radio to hear the spindle better. That rumble before a jam is distinct, like gravel in a washing machine. Screens give you numbers, but your ears give you time to hit the e-stop.

Wait you had to find the speed by ear... that's wild. My old shop teacher would've lost his mind.
