Cobblestone & Stone Generator(s)

Introduction: Cobblestone & Stone Generator(s)

Hi , in this guide I'll be telling how to make different cobblestone generators . At one point , its easier to make a stone generator , so there's also one stone generator among them .

These can be useless at the overworld , in survival , but are the most important machine at skyblock . You can also make one in the end , and make stuff there without having to take lots of stone/cobblestone .

Step 1: Model 1- Super Simple

This one requires one bucket of water and one bucket of lava , and some 2 block high surface .

Dig some of the ground , like the pictures .

Then , place water and lava , and you should have a cobblestone in that blank space between water and lava , destroy the cobblestone and another one appears .

Step 2: Model 2- Super Simple Alternative

This one uses much less space than the previous model , but is just the same .

Make a base or dig the ground , like the photo . I decided to make a base .

Then , dig a hole to stop the water flow .

Now , add lava and water . Works like the previous one .

Step 3: Model 3- Super Simple With Hopper

Both super simple models can be made with a hopper , to decrease amount of lost cobblestone . Sometimes , cobblestones fall into the lava and you lose them , the hopper can help decrease this .

Make a channel for the water and lava like the photos . Then destroy one block and place a hopper .

Now place lava and water .

Step 4: Model 4- Super Small W/hopper

This is the little one with a hopper .

First , place cobblestone , like the photos , to make the base . Then destroy one of the cobblestones and place the hopper .

Now place lava and water .

Step 5: Model 5- Piston Stone Generator

The ultimate stone generator . It creates very fast , and If youre using a stone pickaxe like me , it produces faster than you destroy . It needs 6 redstone , 5 repeaters , a lever , and some non-flammable blocks ,(It requires 2 water buckets instead of 1) , and 2 pistons (normal ones , sticky pistons wont work)

[ I've managed to make another one with 2 less redstone , but I should rewrite it all , and take new pictures :( ]

Steps :

1- place repeaters and redstone and 2 block , like the photo .

2- click on the repeaters 3 times to put them on maximum delay mode .

3- place 2 blacks and a lever on the second one . This lever can be removed but you can keep it to re-calibrate the device if it gets damaged .

4- place pistons . To make sure they are heading the right way , go stand in the front of those blocks and place them

5- make a base for water , like the photo .

6- put 2 blocks like this (No specific block , just used new stone so everyone could understand which blocks have been added .

7- add more blocks .

8- Double click the lever very fast , not very important how fast , it is auto-fixed by the repeaters .

9- add lava

10- add water

You can make a cover for the redstone stuff and for the lava , even for the water . I do not recommend a cover for the water , as in some cases the device might jam , and a cobblestone is created that blocks the way of water , not allowing water and resulting in no stone .

Step 6: Piston Generator's Troubleshooting

The piston generator can sometimes have lag or full jams , or sometimes it will make 1-2 cobblestone on start but continues to make normal stone .

- If no cobblestone is coming , open the redstone part and make sure the signal is spinning around .

If that didn't help , look at the water container and make sure it's not jammed .

- don't mine too fast , this may cause jams for some reasons .

- To make sure your device is running , listen to the piston sounds . They keep making the noise even when they stop working (pistons can't push more than 13 blocks and can't push some blocks due to some reasons . These blocks would be bedrock , obsidian , chests , signs , dispensers and more )

- To stop the device from making more stone , simply put a sign . The pistons can't push it .

-How to restart : Remove the redstone under the lever and wait a bit . The device stops . Place the redstone and double click the lever , fast .

-It's a good idea to put a bunch of signs in the redstone part . Just in case the lava container breaks - only 2 redstones are destroyed , signs can protect the rest .

Step 7: Final

Please note that cobblestone generators are not 100 % stone : sometimes the stones falls into lava . A hopper helps , but the piston one is the best . More minecraft guides are coming soon , including a superior stone generator , more redstone guides and a command block guide .

    This may not work as planned due to Minecraft updates and discrepancies between bedrock and java. This is java version might work on bedrock.

    Why do you say to make the bases out of cobble, but then you use stone in the pics?
