Abstract: A cutting guide for cutting plastic laminate material is used in conjunction with a conventional router. The cutting guide includes an elongate, flat base plate having an opening in one end portion thereof for receiving the bit of the router which has been mounted thereabove. An elongate guide fence is disposed transversely below the base plate and is mounted on a sliding carriage for movement toward and away the router cutting tool. An upwardly biased support roller is axled on the horizontal leg of an L-shaped axle to make rolling contact with a strip being cut from a larger sheet of material along a line parallel to the length of the fence. An auxiliary roller is axled to the trailing end portion of the fence to support the edge portion of the strip of material opposite the cutting tool.
