This invention is a work carriage used with a cutting tool's table surface to make straight-line cuts. The device responds to the need for cutting a wide range of angles and positions on workpieces of different sizes and shapes more accurately, consistently, and safely. The invention consists of a main support which rides on a slide attached to the table surface's guide slot using a wedging action to fill the width of the guide slot. Clamps hold the workpiece to the main support along a t-shaped channel. Once set up, the main support moves precisely along the slide parallel to the guide slot and cutting plane. The main support also has threaded holes to attach workpiece stops and a fence, as needed, for making consistent cuts. A secondary support is used to provide the necessary support with a larger workpiece that has a center of mass beyond the main support.
