Mahogany planks are always in high demand because of their use in the Construction skill.

The player can build a High capacity plank maker Machine in the Invention guild. If provided with Divine charges, this machine will convert logs into planks. The machine requires about 336,000 coins to run for a day, and will convert 960 logs to planks every single day. It can hold up to 7,500 items at once, and thus can be left to run for about a week without any required input.
