How do you make planks?

i think that you take logs to a sawmill, or get some from wildy :]

Chop ordinary trees and take them to the Sawmill Operator. Your logs can be turned into planks for 100gp each.

Chop oak trees and take them to the Sawmill Operator. Your logs can be turned into planks for 250gp each.

Chop teak trees and take them to the sawmill. Your logs can be turned into planks for 500gp each.

Chop mahogany trees and take them to the sawmill. Your logs can be turned into planks for 1500gp each.

The Sawmill Operator is located at the entrance to the Lumberyard northeast of Varrock. He sells saws, cloth and nails, and changes logs into planks for a fee. Players can make nails themselves, of course (using the Smithing skill), rather than buying them here.

find them, or take logs to the man north east of varrok but it wil cost you 100gp per normal log i think more for oaks teaks and what ever the other one is
