Miter table for portable power saw

A portable device for controlling the travel of a circular power saw while cutting wood board, comprising

• (1) a circular base having a flat upper surface
• (a) intended to removably rest on a fixed surface during a cut,
• (b) having on its upper surface a straight edge raised element intended to position a wood board on the base,
• (c) having support means on the outer circumference of the base;
• and
• (2) an outer member having a flat upper surface
• (a) an interior circular opening conforming in diameter to the outer diameter of the base,
• (b) an outer circumference extending beyond the interior opening,
• (c) support means on the interior circular opening intended to cooperate with the support means on the base for rotatably journalling the outer member on the base, and
• (d) a pair of horizontal parallel tracks extending above the base and supported at both ends from the outer member
• (1) the tracks having a horizontal surface on which the circular power saw can be slidably supported, and
• (2) vertically extending portions of the track which laterally restrain movement of the circular power saw while it is positioned horizontally along the tracks;
• whereby cuts at different angles can be made through a wood board by a circular saw in a guided manner, by selectively rotationally adjusting the outer member and tracks with respect to the base wherein said flat upper surfaces lie in the same plane.
