I have a great deal of "true" 2 x 4 and 2 x 6 rough sawn oak lumber from which I'd like to make flooring for a backyard office. Most boards are warped, cupped and/or bowed to a degree. What saw could be used to best slice each board in half...in other words a 2 x 6 x 12' would become two 1 x 6 x...
