Workpiece holder for cutting a 45 degree bevel

A workpiece holder for positioning a workpiece for a bevel cut by the saw blade of a table saw comprising:

• a frame including first and second vertically disposed end plate members and a plurality of stabilizer bars extending between said end plate members and attached thereto;
• said first and second end plate members being identical in size and shape and parallel to each other, the shape of each said end plate member being a right angle triangle having a vertical edge and a horizontal edge of equal length, and an angled edge extending between said vertical and horizontal edges, said angled edge being at a 45 degree angle to said vertical edge and said horizontal edge;
• a base plate having opposed upper and lower planar surfaces, said base plate being attached to the horizontal edges of said end plate members, said base plate having a longitudinal guide rail extending from said lower planar surface, said guide rail being adapted to slidably engage a guide groove located in a table saw top;
• a table plate having opposed upper and lower planar surfaces, upper and lower longitudinal edges, a leading edge and a trailing edge, said table plate being attached to the angled edges of said end plate members, said lower longitudinal edge of said table plate being adapted to meet said table saw top at the edge of said saw blade when said guide rail is engaged in said guide groove of said table saw top;
• and
• a workpiece clamp member attached to said upper planar surface of said table plate and adapted to hold a workpiece with that edge of the workpiece to be beveled in alignment with said lower longitudinal edge of said tale plate.
