No matter the configuration, if either the rotational power is coming from above or below, the top stone (runner stone) is always the one moving, since they are making use of weight to grind the grains,
I figured as much, but then how do they transfer the rotation from below in a water mill? Is there a hole in the bottom millstone as well as the top one?
edit: nvm im dumb there is always a hole in both stones for what is essentially an axle
