I buy my lumber at our local pallet company here in east Tennessee. I buy 4" x 8" square beams that are ten feet long for $7.25 each. I get seven 1x4x 10' out of one log. Oak, cherry, maple, ash, and sometimes walnut. Only bad thing is, the wood is green and has to be dried....also, I get the majority of my wood for free. I help tear down old barns and old houses. A half a days labor usually nets me three or four pickup loads of strait, wide hardwood. ..
