How to Make a Cobblestone Generator in Minecraft

Cobblestone Generator

Cobblestone is a popular building material in Minecraft.

Usually, these need to be mined using a pickaxe, however, there are ways to create an endless supply of cobblestones, without having to carve up the landscape. 

In this article, we will be showing you how to build a cobblestone generator in survival mode as well as the benefits of doing this.

Making a Cobblestone Generator in Survival Mode

In Minecraft cobblestone is created when lava comes into contact with water.

The basic principle of a cobblestone generator is to create the conditions where the two substances can meet and then collect the resulting cobblestone.

There are many different ways to achieve this, but the simplest way is to dig a four-block long trench with a one-block gap in the middle. Then place water in the end closest to the hole and a lava block at the other end. This then creates a cobblestone where the two flowing materials meet.

When you are making cobblestones it’s important not to let the water touch the lava source block or it will be destroyed and turned into an obsidian block.

Pistonless Generators

The usefulness of pistonless generators is limited because cobblestone is readily available and these generators require you to collect the fresh cobblestones from lava.

This not only runs the risk of the cobblestones being destroyed by the lava but also puts the player in danger in case they touch the lava.

Trench Generator

The most basic form of cobblestone generator is the trench generator.

It is important to place the water block first because if the lava begins to flow first it may resist the water and not create cobblestone.

It can also lose some cobblestone to the lava unless a slab is placed over the lava block. This also stops the player from accidentally falling into the lava.

Fountain Generator 

The fountain generator offers more convenient mining and uses two lava streams for production. However, it takes more work to construct than a basic trench.

This more complex generator uses 80 blocks, four buckets of water, and two buckets of lava.

The two blocks of obsidian are optional but help prevent the player from digging through the back wall by accident.

First, build the walls, then place the water source blocks on level 5 and then finally add the lava blocks on level 3.

This produces two blocks of cobblestone at a time and will be washed towards the player when they are mined.

Piston Generators

Piston generators are composed of three basic components.

The core. This is usually based on a basic generator plan and includes the water and lava source blocks

A clock circuit or block detector which drives the piston and pushes the fresh cobblestone out.

A clock generates a signal at fixed intervals. Any basic repeater clock will work but you ideally want a period of at least seven or eight ticks. 

A block detector is a circuit from a power source to the piston. This passes through Redstone repeaters before and after the point where the cobblestone appears. At this point the repeaters p[ush current through the cobblestone and reactivate the piston. Pushing the cobblestone forwards.

Additional pistons. Since pistons can only push a maximum of 12  blocks the core can only produce 13 cobblestones. 

By adding additional pistons to push the blocks in a different direction the capacity of the generator is greatly increased.

Below is the schematic for a basic piston generator.

Level 1

Level 2

The above design uses the same principles as a basic core generator and adds a piston driven by a clock.

The repeaters should be set to at least six as the cobblestone needs time to form.
