According to popular opinion, 1 year per inch for air dry. Your “hobo kiln” would speed that up by XX%.

I like to stack and sticker outdoors first. Once core M.C. is 15% or so, oak is okay to bring indoors and dry in the fashion you describe. Note that any bugs will not be killed unless you reach 140 degrees.

Problems with bringing green lumber directly into the shop include mold on the lumber, and rusted cast iron tools.

Oak has to dry slow, so fans and a dehumidifier on green oak can be tricky to control the drying rate. Go too fast, and you will get case hardening and honeycomb. My red oak green off the sawmill takes about 6 months to air dry to 15% in Georgia, so the 1 year per inch of thickness is way way off.

Buy a moisture meter. Speeding up the process may work against you, slow and easy especially at first, water has to work it’s way from the center of the board through numerous cell walls one molecule at a time. It is not a fast process, if you dry the outer portion too fast the inner wood can’t catch up and that leads to problems such as WDLT15 pointed out.

Thanks everyone, Even at 50 cents a bf i think i am going to pass on the lumber. Having it kiln dried is not feasible due to the minimum amount required. I am not crazy about working with oak anyway and by the time it was dry i wouldn’t need it.
