Timber
From Cantr II Wiki
Timber is used, for example, in the construction of a log cabin. Timber is different from wood, however. It is a separate resource that can be gathered in a jungle or a forest. Timber can in the future also be used to produce planks and logs.
Timber is gathered at a rate of:
0 grams per day without tools (the project can be worked on, but no progress will be made)
2260 gram per day with a 3/4 axe
3000 gram per day with an axe
2200 gram per day with a steel battle axe
The maximum size for a project is 163838 grams.
