Hand Crank

The hand crank is a required block to operate the Mill Stone in Age 0 and the early part of Age 1. It is placed adjacent to (next to) the mill stone, and is right-clicked in order to power the mill stone's operations. It is crafted using two (2) sticks, two (2) cobblestone, and one (1) Wooden Gear. You can find the recipe in the JEI interface.
