Air Drying
Traditional method of drying lumber using natural air circulation.
Beginner
Very slow - 1 year per inch of thickness
About This Technique
Air drying lumber relies on natural air circulation to slowly remove moisture. Boards are stacked with spacers (stickers) between layers to allow air flow. The traditional rule is one year of drying per inch of thickness.
Historical Context
The only drying method until kiln drying became common in the late 1800s. Still preferred by many craftspeople for its gentle treatment of wood.
Tools Required
Stickers (spacers), level ground or foundation, roof or tarp, end sealer
Advantages
No energy cost, gentle on wood, develops rich color, minimal equipment
Considerations
Slow, weather dependent, cannot reach low moisture levels
Modern Relevance
Many woodworkers prefer air-dried lumber for its workability and color. Often combined with finishing in a kiln.
