Thank you, I will bookmark this. The times that I quote have worked for me. White oak has a membrane, so to speak, within the grain that makes the wood almost waterproof. This makes it just as hard to remove the moisture.

There are some commercial dehumidifiers that will work nicely in a homemade kiln. Some have heat as well. A word of note, If you dry wood too fast, especially for thicker stock, you can create a situation where the ends are dry and the center isn’t. Moisture works a little like a rubber band, when it is moving, it tends to pull other moisture with it, if the band snaps, the remaining stays put. The same happens when you heat the wood, it changes. When a part of the wood gets down to a certain level of dry, it is less likely to move water – in or out.
Sometimes slow – if you can wait – is good. The slower you dry wood, the less the checking – unless it is under stresses from bends and twists.
