What is the fastest way to dry wood for woodworking?
The fastest way to dry lumber is by kiln with high temperature and high airspeed. These can dry lumber with a thickness of 25 mm in about 10 hours to a moisture content of 18%. However, if you want to dry lumber to a moisture level of 8%, an oven needs about 28 days to dry.
Can I kiln dry wood at home?

What moisture level is acceptable in wood?
In order to be usable for a construction project, wood must be kiln or air-dried to a moisture level of 19%. But wood that is intended for indoor use— that is, wood intended to be used for woodworking— must have a moisture content level that is less than half that amount, at only 9%.
How can you tell if wood is kiln dried?
Ways to tell if firewood is kiln dried include:
- It’s stated on the bag that the wood is kiln dried (if it comes in a bag).

This can speed up the drying time from months or weeks to just a few days. Even better is if you add an air fan into the mix to produce some extra airflow.
How can I dry wood fast without cracking it?

Is it OK for kiln dried wood to get wet?
Even though high humidity is the major problem, it should be emphasized that kiln dried lumber should never be exposed to rain. This inevitably leads to severe surface checking, a loss in color quality and many other forms of degrade depending on the species.
What humidity should kiln dried wood be?
6-8 percent
