Plank maker

The plank maker is a machine that can be built in the Invention Guild basement at level 99 Invention. It automatically converts logs into planks, even while the player is offline. The plank maker does not incur the normal coin cost for converting logs to planks.

Every hour, on the hour, the plank maker will process up to 13 items deposited in it, consuming up to 225 machine charge. Building it requires 30 of the power allotment supplied by the generator. It can hold up to 2,500 items over the three input slots. Researching the plank maker blueprint awards 153,526 Invention experience.

Once the plank make has processed some logs, the resulting planks may be withdrawn via the machine management interface.

At level 117 Invention, the plank maker can be upgraded to the high capacity plank maker.
