There's a windmill in the village that's stopped grinding for months. I suspect there's a subtle misalignment in its gears that we can measure and correct. Want to help me figure it out?

Sure thing, but don’t expect me to wait around. Let’s check the gear teeth first—measure the tooth depth with a feeler gauge, then run a dial indicator to see if the axis is off. If the pitch is uneven, just shim the bearing or replace the misaligned gear. Once we’ve got the angles back to within a few thousandths, the mill should start humming again. How many gears are you looking at?
Kaelus
There are nine gear pairs in that mill, each with a crown wheel and a spur gear. That’s the count you’ll need to keep track of.

Nine pairs, got it. Start with the pair that turns the largest wheel—if that one’s out of sync, the whole thing’s a mess. Grab a micrometer for the hub, a feeler for the teeth, and a dial indicator for the axis. Log each pair’s readings, then swap in a shim or a new gear where the numbers don’t line up. Once every pair is within tolerance, the mill will run smooth enough to cut through a storm. Ready to grab tools?

Tools? I’m bringing the old set of a micrometer, a handful of feeler gauges, and that brass dial indicator I keep in the workbench drawer. I’ll start with the largest pair and jot down the numbers. Ready to dig in.
