Abstract: A guide comprises one or more brackets for securing the guide to a cutting tool, a horizontal support member secured to and moveable with respect to the brackets, and one or more arm assemblies secured to the horizontal support member and adapted to secure a working piece relative to the horizontal support member. With the working piece secured to the guide in this manner, the working piece may be readily advanced over a blade of the cutting tool by grasping and moving the horizontal support member relative to the brackets, thus ensuring a precise cutting of the working piece while also allowing a user to keep their hands away from the blade.
Abstract: An apparatus for cutting dados in two boards used to form a box joint includes a support member and a rear member adapted for securing the apparatus to a miter of a table saw or to another type of a woodworking power tool. An insert assembly in the support member includes an adjustable elliptical pin having an oval shaped cross-section. The elliptical pin is adapted for rotational placement into a dado cut and, subsequent to its rotation sufficient to remove all slack intermediate the pin and the boards followed by a tightening thereof, for securing the boards in place for subsequent dado cuts. An insert is placed in the insert assembly and is used to establish the proper offset from the elliptical pin to a dado blade or other type of a cutting instrument. Different sized elliptical pins and inserts are used with different sized dado blades or cutting instruments. The step sequence necessary to make all of the dado cuts in both boards is described.
Abstract: A carrier adapted to securely hold a workpiece for manual movement through cutting engagement such as with the saw blade of a band saw in a manner that allows for precise and predictable cutting of the workpiece into boards of desired thickness. The carrier is slidably positioned in the miter guide slot that extends in the saw work table parallel to the cut of the saw blade, and is adapted for manual positioning of the workpiece transversely with respect to the guide slot to adjust the depth of cut of the blade into the workpiece.

Abstract: An apparatus includes a structure supporting a circular blade, a carriage on the structure for linear movement relative to the blade, and a lathe mounted on the carriage, the lathe rotatably supporting a workpiece in proximity to the blade. In one aspect, the support structure is pivotally connected to the carriage to allow pivoting of the lathe between an orientation for engagement of the workpiece with the blade and an orientation in which the workpiece is supported remote from the blade to facilitate operations on the workpiece with a tool implement other than the blade. In another aspect, the support plate is moveable with respect to the carriage in a direction orthogonal to a line parallel with the direction of allowed movement of the carriage relative to the frame, and a pattern plate is mounted to the support plate to control workpiece depth of cut.
Abstract: A machine for use with a table-mounted router to form a wide variety of woodworking joints by manipulating a workpiece to engage the router cutter in predetermined locations, in some instances by reference to a joint element template, and in other instances by reference to predetermined lateral locations, to form joint elements with predetermined shapes and spacing.

Abstract: The present invention is a jig system for precisely positioning the placement of multiple cuts such as in the placement of dovetail or box joints cut in a wood panel. A row of multi-use adjustable spacers controls the indexing of a workpiece and can be used with a stationary and/or a portable cutting tool. The movability of the spacers permits a workpiece to be cut on both sides of a guide bar fence thereby assuring that the first cut will always be made on the same side of a drawer and will be esthetically pleasing regardless of the width of the workpiece. Additionally, the adjustability of the spacers accommodates any desired cutting tool height, angle and/or size.
