In Roblox Timber! , the usual way to turn trees into fuel timber is to cut the tree into logs and feed those logs into the fuel/processing setup so they can be used for crafting, power, or selling depending on the machine in your build.

Quick Scoop

From the Timber! guides and forum advice, the basic flow is:

  1. Chop a tree down until it becomes logs.
  1. Move or send the wood to the right conveyor or output path.
  1. If you’re using a machine that needs fuel, place the wood or coal in the fuel input and let it process.
  1. Collect the output, which may be fuel timber, processed wood, or sellable logs depending on the machine.

What players are saying

A Timber-related forum post explains that for an industrial tree cutter, you place a sapling on the opposite side of the input conveyor and add coal as fuel; when it finishes, both wood and a sapling appear at the output. Another Timber guide shows that farming a strong tree repeatedly can generate large amounts of logs, which players then sell or use for progression. That means “fuel timber” is usually part of a machine loop rather than a separate tree type.

Simple setup

  • Chop trees for wood.
  • Use conveyors or a filer/planter setup if you have automation.
  • Add the required fuel, often coal, if the machine asks for it.
  • Collect the finished timber from the output side.

Practical tip

If your goal is money or fast progress, focus on higher-health trees and repeatable farming spots, since guides show those produce far more logs over time. If your goal is automation, the industrial cutter setup described in the forum is the clearest example of how fuel is used in the tree-to-timber loop.

TL;DR

In Timber!, you usually chop trees into logs, feed them into the right machine, and add fuel like coal if needed to produce timber or processed wood.
