Make sure you're actually using the High capacity plank maker, instead of the regular Plank maker. If you do not, the profit gained from this activity will be lower than shown on this page.

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.

With a Jumbo generator, up to two High capacity plank makers can be run at a time, potentially resulting in doubled profit, at the expense of being limited in terms of what other machines can be used. To allow profit to be easily calculated for any combination of machines, this page calculates profit on a per-machine basis.
