Wrench (BuildCraft)/bg

The Wrench, added by, is the primary tool for manipulating the orientation of BuildCraft pipes and engines.

Pipes
The wrench is used to manipulate the orientation of s, s, s and s. For a Wooden Pipe that is between two extractable machines or chests, right-clicking on the pipe with the wrench will change the side that items or liquids are extracted from.

Using the wrench on an Iron Pipe will change the output direction of items or liquids, since Iron Pipes have multiple inputs but only one output.

Engines
The Wrench reorients the direction of engines if there is an appropriate item block next to the engine, such as neighboring machines or pipes.

Thermal Expansion
The BuildCraft wrench also changes the direction of the side face of machines from the mod.
