Abstract: In one or more arrangements, a guide system for woodworking operations is presented which has a rail and a pair of side members operably connected to, and adjustable along a length of, the rail. In one or more arrangements, the side members are connected directly to the rail while in other arrangements the side members are indirectly connected to the rail, such as through use of a front member. In some various arrangements, the side members are laterally adjustable in order to accommodate various shapes, sizes, and configurations of base plates on various cutting members.
