Abstract:
1. A saw comprising: a table having an elongated axis; a rotary joint fixed to the table and rotatable about the elongated axis in response to an external torque; a longitudinally extending guide rail spaced radially from the elongate axis and fixed to the rotary joint to pivot with respect to the elongated axis during rotation of the rotary joint, the guide rail having a shape selected from the group consisting of an annular cross-section, cross-shaped cross-section, I-beam cross-section, regular polygonal cross-section and an irregular polygonal cross-section; a saw housing receiving a saw blade and mounted on the guide rail; and a linear motion bearing assembly mounted between the guide rail and the saw housing and rotationally fixed to the housing to provide linear displacement of the saw housing along the guide rail, the linear motion bearing assembly and the guide rail being shaped and dimensioned to prevent rotational movement relative to one another during angular displacement of the saw housing between beveled positions of the saw blade, wherein the saw housing has a lever provided with opposite ends, one end of the lever having a bore receiving the linear motion bearing assembly, and the other end of the lever being coupled to the saw blade rotatable about a saw axis which extends transversely to the elongated axis.
