Wooden Axle
The Wooden Axle is used to transfer continuous mechanical power in conjunction with Gearbox.
These wood and rope devices are only able to handle 3 blocks in a row before breaking under the stress. This is where Gearboxes come into play, allowing junctioning and repeating the signal from the Axle.
Axles are also where [Windmills] and [Waterwheels] are placed to begin creating Mechanical Power
