Cobble gen best one?

This thread is for anyone who has a cobble stone generator. post your ideas here. its not a competition but if it was who will win? ill start.

First the floor.

We'll remove the wood later just showing where to put the holes in the ground.

Next we build 8 pillars to hold the water doesn't mater how high.
Notice the pillars are around the wood (soon to be holes).

Next comes the water. fill in the top and leave 4 spaces in the center and on the edges.
The 4 spaces in the corners are for water.

Remove the wood if you put it there as a guild line. Place water
Off to a good start but wheres the lava come in?

Now put a cover over the water sorce blocks. and fill in the middle 4 cobble with 4 air on top.
Doing great.

Now for the lave put your 1 bucket in 1 of the 4 air spaces on top. and dig out the cobble below.
Perfect.

Now just mine and build your island as big as you want.

Decorate how ever you want. my island has 4 of these with 1 lava in it Good luck.

 

Very efficient and reliable.
