Wooden Gear

Gears are necessarry to craft Buildcraft Enginesand machines, like the Quarry. The gears must be constructed sequentially, so in order to make one diamond gear you need four sticks, four cobblestone, four iron, four gold and four diamonds. To make a wooden gear you must put sticks in the top middle, bottom middle, middle left and middle right. In order to upgrade, put the previous gear in the center and surround it with your chosen material as you did with the wooden gear.
