Yesterday and today I started building myself a cobblestone generator. I found a great guide on the minecraft forums and rebuilt one based on the diagrams.
I started with an empty island not too far from spawn.

I flattened it out, tested the generator I’d seen online to see that it worked, and then built a fully functional factory for craeting cobblestone and then converting it to rock.

I chose to use an iron door activated by levers to make it look more factory like without letting mobs inside.

This here is a screenshot of the whole inside part of the generator.

It works by mining these two cobblestones here, as you mine them, the lava and water regenerate the cobblestone in the same spot.

This is a view from the roof of the factory.

Once the cobblestone has been mined, it is sent to the next area by storage minecarts.

It is either sent to the furnace room where it is converted to rock.

Or it (like the rock) is sent to the storage area in the middle of the factory.

I’ve also taken the time to build a subway station that passes through the area, although once I’ve eventually built a central hub, I may build a second line from the factory to a secure storage area somewhere.


That’s it for now, still trying to decide what to build next, any thought or suggestions would be appreciated.
