9,000 x mahogany plank (14,706,000)
Making mahogany planks at the sawmill has long been a decent way to make money. With portable sawmills being added, this method is now much more profitable. At the portable sawmill, each plank requires one mahogany log and 1350 coins to make. To make planks with maximum efficiency, deploy a portable sawmill near a bank or bank chest (for example, near the bank chest in Castle Wars), make a preset with 28 mahogany logs, and load it. Then click the sawmill and choose to make planks. Additionally, you can use portable sawmills on the one already deployed to increase its duration by five minutes per sawmill. You can make just around 1000 planks on one portable which gives 12000 planks per hour at max efficiency. If you have a Construction cape, you can wear it to save about 150gp per log on a portable sawmill. Thus increasing your profit per hour by about 1,350,000gp
