Iron ingot farm - 20 mills - 32 ingots/15 minutes - by Tryhardion
I have decided to make efficient iron farm. After placing the schematic, put lava and water as you can see in the pictures + infront of every encased fan. Than just turn on the windmill or replace it with your own powersource. The rates are approximately 32 ingots per 15 minutes. The contraption was made so it wouldn't clog the machine, so you don't have to worry about that.
