This is an Ice Factory I created. It generates about 2000 ice per hour. When the schematic has been imported you will need to place water to power 2 water wheels. There are also stairs in the farm that all need to be waterlogged. The farm needs a player to be nearby to spawn ice and needs to be supplied with silk touched pickaxes to work. There are two valves set to turn 45 degrees, these can be right clicked to get the roof into it's slanted position as a contraption. The mechanical bearing should be set to only place blocks in it's starting position.
