Ok, so I managed to finally get a diamond transport pipe. Since there are so many things I want sorted, I had to use two sides of the pipe to get everything I wanted. I have about 13 items going to one chest and a two cobblestone pipes that merge into one pipe that leads to the chest. At the point where the two cobblestone pipes meet, the items that I want going one way, head backward up another way. Is there a way I can force objects to go one way so that every item heads to the chest, and not circles around? Thanks for helping.
