A millstone is used to grind up certain plants to make flour and dye. To operate, it needs to be connected to a mechanical power source such as a water wheel or windmill that supplies it with 10 power units. If none is available, a quern can be used instead.

If the power to the millstone is interrupted, any jobs must be requeued when power is returned. Therefore it is best to have uninterrupted power or at least the ability to run it for a long period of time.

Here, the windmill is built "hanging" on top of the millstone. You can build walls around the millstone if you like, but they're not required. Once the windmill is built, the access stairwell can be deconstructed. Since the windmill is "hanging" in midair, removing the millstone will cause the windmill to fall down.

(Alternatively, the whole operation can be shifted down one level, so the windmill is built on a stable surface on the ground level and the millstone is underground.)

Level -2 has the millstone built beside a gear assembly.
Level -1 has a vertical axle built over the gear assembly (first remove the floor by designating a channel). You can skip this level if you want a millstone right below the surface, or you can repeat it multiple times to take power deep inside the mountain.
Level 0 has the windmill (the center tile is above the vertical axle).
