If there is too much air flow on green red oak and it is drying too fast, the core of the boards will honeycomb. I would not run a fan on air drying red oak until the moisture content of the wood is below 30%. Then, the fans will be a big help without the danger of honeycombing. Some species like maple, yellow poplar, pine, can stand the fans immediately after sawing, and this is important because maple and poplar are prone to sticker stain and gray stain. The air flow from the fans speeds the drying and really helps to prevent staining.

Nothing wrong with using air dried wood for furniture if the air dried wood is stored with stickers between the layers in a heated and conditioned interior space for about 4 – 6 weeks for red oak. It needs some time inside to acclimate. I did an experiment with some 7/8” thick red oak where I stacked some in stickered layers behind a couch in my house in Georgia in April. Initial moisture content was 13.5%. After 5 weeks the moisture content was down to 9.5%, and it stayed at that level for the next 4 months.

Wood in most climates except for the dry desert will not dry to below 12% moisture content outdise. 15% in most cases. Giving it time inside to acclimate reduces the danger of additional shrinkage in use in a piece of furniture and just requires a little pre-planing and patience.

When it comes to fast drying, the word “fast” is not in a red oak’s vocabulary.
