Mahogany plank

Construction
Mahogany planks are made by taking mahogany logs to the Sawmill operator near Varrock to be converted into planks for a cost of 1500 coins. Alternatively the Lunar Magic spell Plank make can be used (and can make a small profit depending on the exchange price. Planks are then used in the Construction Skill to make high level furniture. Mahogany logs are the most expensive of the four types of planks and give 140 Experience points each. It is also sometimes used to make money by making furniture with it then selling to people with lower construction levels.

Tip
If players have access to the Balloon transport system they may use it to make Planks quickly. Start at Castle Wars, using the Bank chest, and use the balloon to travel between there and the Varrock Sawmill. Due to weight restrictions, players may only carry about 18 logs to be made into planks at a time (as well as the money to make the planks and the Willow logs for the transport and a Ring of duelling to return to Castle Wars. Players can take the maximum 26 logs per trip by using Weight-reducing equipment.

Note: Familiars cannot be used on the balloon transport system.
