Hey Mark, The average time recommended to air dry most hardwoods is one year per 1" of thickness. Your best solution is to find someone with a wood kiln. There is a lot more things that need to be done to air dry, From stickering and stacking, to sealing the ends of the board and so on. Then when the wood is ready to work, you will need to mill the wood. You will need a planner, Jointer and table saw. So is it worth it to you? There is no wonder why hardwoods cost us so much.
