  • Patent number: 12172259
    Abstract: A straight edge guide system is presented that makes clamping of a workpiece faster and easier. The straight edge guide system includes a guide member that extends a length from a first end to a second end. A clamp member is connected to the first end of the guide member and includes a compressible bias member therein. An adjustable stop member is connected to the guide member that moves between a locked position and a free position. When the adjustable stop member is in the free position, the adjustable stop member slides along the length of the guide member. When the straight edge guide system is placed on top of a workpiece, the workpiece is clamped under spring bias force between the clamp member and the stop member.

  • Publication number: 20230382003
    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.

  • Patent number: 11787078
    Abstract: A portable cross cut system is presented that includes a main body having a reference edge configured to be aligned against an edge of a workpiece and an engagement member configured to be laid on top of the workpiece. A first guide edge extends along an outward edge of the main body and the engagement member and is configured to guide an edge of a baseplate of a cutting tool during a cutting operation. The main body includes a blade offset member having an arm that moves between an extended position and a retracted position. When the arm is extended the outward end of the arm indicates the position of a cut line so that the user can easily align the position of the portable cross cut system to easily and accurately make cuts in a workpiece.
