Abstract:
1. A portable sawmill with bi-directional cutting circular saws, comprising: a primary support structure having a first end and a second end; a log support supported by the primary support structure; a saw support supported by the primary support structure above the log support; means for providing relative movement between the log support and the saw support in a first direction from the first end toward the second end and in a second direction from the second end toward the first end; the saw support being pivotally mounted to the primary support structure for pivotal movement about a pivot axis which is transverse to the direction of movement; two circular saws rotatably mounted one above the other on the saw support, a first one of the two circular saws rotating in a first rotational direction and a second one of the two circular saws rotating in a second rotational direction, with the teeth on both of the two circular saws always moving toward a log resting on the log support as the log is being cut; and an actuator for selectively pivoting the saw support to invert the positioning of the two circular saws so that the teeth on both of the two circular saws continue to move toward the log being cut upon a change in direction occurring.
