Ok this is not the most efficient system in the world. But this should be something you could make in the first hour or two of game play. You can get loads of cobble and usually enough iron for two buckets. If your not into collecting a bunch of cobble by mining you can usually fine at least one block of lava within the first hour if you dig down and could use that to make cobble gen. Obviously this is much easier in modded MC but since everyone keeps asking me how I can get stacks of ender...
