Abstract: An inexpensive jig for holding a piece of crown molding, and guiding a hand-held jigsaw at a particular angle to aid in coping the molding. The jig has a horizontal base plate 1 and two vertical side fences 2A, 2B. A guide plate 3 is attached between the front ends of the fences, and is spaced from the base plate by a gap 5. The guide plate is oriented as if rotated through two particular angles about two respective axes from a position normal to the fences and base plate. The resulting front surface of the guide plate guides a jigsaw in the coping process. An opening 4 in the guide plate is aligned with the upper surface of the base plate, and allows molding to be placed on the base plate with an end in the opening to interfere with the jigsaw blade at a desired coping angle. First, the molding is placed inverted against a miter saw fence, and an end of the molding is cut at a 45-degree angle. Next the molding is placed in the jig, with the cut end in the opening of the guide plate.

Abstract: An architectural millwork jig for the cutting of at least one cope in a strip of architectural millwork such as crown molding. The jig includes a base for stabilizing the millwork and further includes a table with a through opening positionable over the end face to be cut. A powered jig saw rides on the table about the opening, where the powered jig saw includes a foot for riding on the table and a blade reciprocating between two toes of the foot, and where the blade makes the cut in the end face of the millwork. The table is swingable about at least the x and y axes so as to provide a proper alignment for the surface of the table on which the foot of the powered jig saw rides. Swinging of the table about one axis permits one jig to be used for right hand and left hand copes and further permits the table to be adjusted to the exact angle of the right hand cope or to the exact angle of the left hand cope. Swinging about this one axis further permits the table to be swung into position to cope flat miters.

Abstract: A saw system includes a support table (12) and a first elongate tower assembly (50) pivotally mounted relative to the table (12). A second elongate tower assembly (60) is also mounted for rotation relative to the table (12) and is spaced from the first tower assembly (50). The second tower assembly (60) is moveable towards and away from the tower (50) by roller wheels (42 and 43) which engage on guide rails (34 and 36) to enable the second tower assembly (60) to be moved. The second tower assembly (60) and the first tower assembly (50) are rotatable to set the tower assemblies at a predetermined angle with respect to the table (12) and carry saws for making a cut in the workpiece. Ram assemblies (130 and 160) on each tower enable movement of the workpiece downwardly relatively to the saws so that the workpiece is driven past the saws and cut by the saws.

Abstract: A miter attachment capable of use on radial saws, table saws, drill presses, router tables, and the like, comprises three legs of a triangle. The longest leg constitutes an elongated base member. This base member is pivotally attached at one end to a fence member. The base member has a track in it for engagement by a slider, which is capable of movement along at least a portion of the length of the base member. The slider is pivotally attached to one end of a coupler arm, the other end of which is pivotally attached to the fence member at a point spaced from the end pivotally attached to the base member. As the slider is moved to different relative positions along the length of the base member, the coupler arm causes the angle between the fence and the base member to change.

Abstract: The invention is directed to measuring the length of a piece of wood to be cut in a miter box, a frame and trim saw, a radial saw and the like. The miter box includes a back (24) having a surface (24a) against which the piece of wood is placed and slid into position for cutting by the saw blade of the miter box. A roller (30) is positioned at and extends slightly beyond surface (24b), and is mechanically and thence electrically connected to a LCD display (54). The roller is mechanically connected to a rotary disc (42) by any suitable means, such as by a secondary roller (34) and gears or by a cord (40) and pulley mechanism. Wiper contacts 60 are slidable on and against a surface of disc (42), and are electrically connected to LCD display (54). A reset switch (68) and/or a spring switch on surface (24a) enables the reading on display (54) to be reset, for example, to 1/2" which is the distance from a starting point and the path of saw blade travel.
