Sawmill

The Sawmill is your way to increase your wood-output. It is a basic machine that uses EU to cut your logs down into planks. It takes 320 Ticks (16 Seconds) to process 1 item and it uses 2EU/t.

The Sawmill GUI contains 7 slots and 2 indicators. The upper-left and center-right slots are the same input/output as a regular Machine. The lower-left slot can hold an RE-Battery to power the machine. The lightning bolt symbol is a charge indicator, showing how much EU the Furnace contains. The right four slots are Upgrade slots. The Sawmill can accept Machine Upgrades and Inventory Upgrades.

The Sawmill has Specialized Upgrades which allows it to speed it up for almost no Powercost increase.
Because of these Upgrades the Sawmill is a machine that has no Advanced Version of it.
