Portable sawmill detail

The portable sawmill is an item won on Treasure Hunter that acts as a lumber mill when planted. Planks made using it receive a 10% discount.

It can be placed anywhere that you can light a fire and is both visible to and usable by all other players. It vanishes 5 minutes after being placed. When using the sawmill, players are asked how many logs they would like to convert into planks. The cost for making a plank with the sawmill is 10% lower than the cost from the Sawmill operator.

Profit calculator

The following table estimates profit for every 1,000 logs turned into planks. Milling rates are typically around 8,000 planks per hour, but easily can be higher with use of a one-step bank, such as at the Combat Academy bank chest in Lumbridge, along with a bank preset with mahogany logs.
