Tekkit Version	v3.1.4

BuildCraft is the oldest Minecraft mod which revolves around automating tasks. Its best known for its machines and pipe-based transport systems, which are all powered by engines.

Uses

BuildCraft has two main uses: the moving around of items via pipes and engines, and digging, pumping and mining with various machines. The BuildCraft mod really is the key to world automation, as it is compatible with almost every other mod, and definitely those in the technic pack; it is the best option for moving items from place to place. Mine factory does this to some extent with its conveyer belts, but the BuildCraft options are far more advanced.

  @blackopsman99999 The new version (v2) makes ctenlbsoobe as fast as 4 quarries. You can see it by going to my channel. I also have an unreleased version that has a skeleton trap that makes bonemeal to get wood faster. That can fill up 12 chests of tools in 30 minutes. I don't think there's any need to make it faster, and quarries are expensive. I want this to be renewable and realistic to build legit.
