As pictured above, putting two chunk hoppers in the same chunk (one into a chest and one into a dispenser) allows for duping. Fill the dispenser and it's chunk hopper with whatever item you want to dupe and just start dispensing the item. The dispensed item will be collected by both chunk hoppers in the chunk thus doubling the amount of said item.
