Abstract
The present invention involves a metal structure which has provisions for mounting a common hand held electric circular saw while supporting the wood being cut. Using the same tool, a woodworker may make accurate crosscuts, miter cuts, compound cuts, and rip cuts in a wide variety of wood components. Adjustable support wings can be employed to support long pieces of wood, particularly during the ripping process. Integrally mounted wheels provide means for easily moving the invention from one place to another. The invention's small size and light weight allow it to be stored when not in use.
