Oak Boards and Blocks, Milled and Air-Dried

The same chainsaw mill that cuts pine boards cuts oak, but oak dries slowly and checks if it dries too fast. The old rule of a year per 25 mm of thickness is close for oak. Thin boards are cut for joinery; one thick slab is kept for blocks. Compared with pine: a slower cut, a heavier log, and a drying time measured in years, not months.
