Andesite alloy farm

I present to you a farm of andesite alloy and gold nuggets, housed in a 19th-century building.

To get the farm fully operational, you'll need several buckets of lava and water. Pour the water into all the leaves, and pour the lava into the cauldrons and between the leaves near the drills.

Once all the liquids are in the right places, all that's left is to turn the speed controller (no matter which direction), BUT make sure it's set to 16 counterclockwise.

There's enough space under the building's roof to build a base or warehouse (if desired). Building a staircase from the first floor up will be enough.
