Hiya, all you vintagestoryers. I am coming to you today because, I, had an epiphany. I have myself reached the late stage point in the game where I produce a lot of grains, and my quern can simply not keep up anymore. So I thought, "Wouldn't it be nice if we had a larger sized quern?" And then it hit me! We already do!
Mill stones! So my proposal is as such. There are 2 components, the bed stone, 9 stone blocks, place fiest, fills a 3×3 space, then the runner stone. 6 stone blocks, same size, and goes on top! You connect it like you would a quern, and instead of only accepting 1 stack at a time, you can grind 3 separate stacks at the same time eith 3 separate outputs for each stack!
Of cause such a large mill is not cheap and will require a beafy mechanical power drive, but if you can run it you can process flour/grains way faster.
