Provided are a porous media bearing for a band saw, a band saw for cutting cant and a method of cutting cant using the band saw. The band saw has a continuous loop blade supported by a drive wheel and first and second support arms having porous media bearings. A location of a blade cutting section, an angle of the blade in relation to the cant being cut, and tension on the blade can be adjusted by moving the first and second support arms.
