1. A saw support for cutting a workpiece, comprising:
- a frame having at least one side edge and at least one end edge;
a supported table slidably mounted to a free sliding supported carriage assembly mounted on said frame, said table being adapted to support the workpiece thereon, the table having an upper surface aligned in a predetermined plane;
a motor assembly operatively supported by said frame including a motor and a saw blade connected to the motor to cut the workpiece; and
said free sliding carriage assembly being mounted for movement parallel to the edge of the frame for cutting of the workpiece such that said table and free sliding carriage are moveable to a predetermined position beyond at least one end of said frame.

Abstract
A saw with a compact frame that permits the cutting of large workpieces and that can be repeatedly operated repeatedly without requiring manual activation of an on/off switch. A special pivoting support arm pivots outwardly away from a motor assembly to allow the cutting of large workpieces while allowing the size of the saw to remain relatively compact and portable. An automatic power switch mechanism also is provided to automatically turn on the saw motor upon the placement of a workpiece adjacent to the saw blade. The saw table can be slid beyond the frame for the cutting of large workpieces.
