A band saw includes a first blade guide assembly and a second blade guide assembly which guide the band saw blade through a cutting zone. The first blade guide assembly and the second blade guide assembly are each supported for pivotal movement about a pivot axis between a first angular position and a second angular position. At the first angular position, the first and the second blade guide assemblies hold the band saw blade at a first angle with respect to the wheel contact plane. At the second angular position, the first and the second blade guide assemblies hold the band saw blade at a second angle with respect to the wheel contact plane, the second angle being different than the first angle.

In a band saw that is provided with a tension adjustment mechanism in which tension for an band saw blade can be adjusted, first and second wheel support shafts are provided in paired first and second wheel support portions, respectively, such that the first support shaft is parallel to the second support shaft. The first wheel support portion is configured to be movable in a direction in which a straight line extends, the straight line being perpendicular to both the first and second wheel support shafts. A first support is provided at a first end of the first wheel support portion, and a second support is provided at a second end of the first wheel support portion. Furthermore, an intermediate support is provided between the first support and the second support. A first load and a second load are configured to be applied to the second support and the intermediate support, respectively, such that the first load and the second load are parallel to the wheel support shaft and the direction of the first load is opposite to that of the second load.

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.
