Abstract: A concrete cutting machine, for wet and dry dual-use cutting, includes a saw blade, which is configured to cut concrete, a motor, which is configured to drive the saw blade to rotate about a first axis, and a bottom plate, which is configured to support the motor and the saw blade. The bottom plate is formed with a first cutting space for the saw blade to pass through. The concrete cutting machine further includes a sliding plate assembly, which is at least partially disposed in the first cutting space, to form a second cutting space smaller than the first cutting space.

Abstract: A fence attachment apparatus for a table power tool equipped with an existing rip fence has a longitudinal member that includes a first side member having a top surface, a bottom surface, a cutting-side lateral surface, and a fence-side lateral surface. The longitudinal member has a bridge member that extends transversely from the first side member and connects to the first side member along a major portion of the first side member adjacent to the top surface. The fence attachment has a sliding member in sliding engagement with the top surface of the longitudinal member, where the sliding member has a top sliding surface and a bottom sliding surface. A slide mechanism is disposed between the bottom sliding surface of the sliding member and the top surface of the longitudinal member, where the slide mechanism provides longitudinal movement to the sliding member.

Abstract: An assembly is used upon a powered saw table to accurately cut at a centerline of a workable piece or other material to be cut or, if desired, to accurately cut the cheeks of a tenon to fit a mortise. The trigonometric functions of a right triangle—sine and cosine—are used to assure that as a component of the assembly is moved a certain distance longitudinally, parallel the cutting direction of the saw blade, the guide fence is moved just one-half that distance toward the blade. The longitudinal distance moved is made to equal the width of the piece, thereby indicating a centerline. If the width of the mortise is also considered in addition as part of the longitudinal distance moved, the guide fence is moved toward the saw blade just one-half the distance of the combined widths of the piece and the mortise, to cut the tenon cheeks.

Abstract: A guide assembly in one embodiment includes at least one guide rigidly supported by a table saw, a bearing assembly including a first, a second, and a third bearing engaged with the at least one guide, and a fence base assembly supported by the bearing assembly, wherein the first and the second bearings are biased in a first direction with respect to the at least one guide and the third bearing is biased in a second direction with respect to the at least one guide, the second direction at least partially opposite to the first direction.

Abstract: A fence engagement and blade guard includes a column mounted to a table saw with a horizontal member received in a channel in the column. A vertical rod extends through and is vertically adjustable in a hole in the horizontal member. An engagement cart is suspended from the vertical rod and includes a beam having axle apertures and axles received in the apertures to support wheels. The wheels frictionally engage a work piece. An axle suspension system is supported from a shield. The engagement cart is angularly rotatable for engagement of the wheels on the work piece to directionally urge the work piece against the table saw fence.

Abstract: A sheet material punching device comprises punching pins, a die member having die holes formed therein, a frame having a housing space defined by wall portions inside to house therein the die member and the punching pins, the frame having a longitudinal direction extending in a width direction of a sheet material W, and paper feed ports formed in the wall portions of the frame for the sheet material W to be transported through, wherein the die member being bridged across the paper feed ports is supported in a predefined length in the width direction of the sheet material W. The sheet material punching device thus configured can prevent deflection of the die member caused by a punching force applied to the die member by the punching pins during the formation of punched holes.

Abstract: A mounting system for a table saw accessory such as a power feed. A carrier is slidably mounted on a rail or flange at the rear of the saw table so that it may traverse the rear of the table. The rear of the saw fence is secured to the carrier. A mounting plate for the power feed is on either the carrier or the fence allowing the power feed to be moved between use and out-of-the-way positions. In the out-of-the-way position, the power feed allows the user to safely feed materials into the cutting blade area.

Abstract: A fence assembly for a cutting machine includes a body which is adapted to guide a workpiece on a worktable during cutting process. A coupling mechanism includes a sliding bracket slidably mounted to a rail and connected to the body such that movement of the bracket along the rail causes movement of the body relative to the worktable. The sliding bracket is adapted for providing stable sliding movement with respect to the rail and engaging with at least three sides of the rail. A locking mechanism is utilized for selectively locking and unlocking the sliding bracket on the rail.

Abstract: The present invention relates to a manual vegetable cutter, for selectively varied cutting. Furthermore, the cutter of the present invention does not expose the user to risks of serious cuts. The cutter comprises a frame fitted with at least one cutting blade mounted transversely facing a slot through which the cut vegetables pass and also two side rails providing guidance in to and fro translational motion for a guide chamber equipped with a loading volume for the vegetables to be cut up and acting in conjunction with a press-down cap which the user grips in order to move the guide chamber to and fro along the guide rails while constantly exerting pressure on the vegetables contained in the loading volume so that they are pressed against the cutting blade or blades fitted to the frame and can be cut up by the blade or blades.

Abstract: The multi-functional woodworking adapter for use with a multi-functional woodworking guide is a modular portable universal guide, adapted for guiding multiple hand held power tools, that is extendable with the use of multiple guide plates, side bars and edge bars in order to increase the size of the guide device to any length, thus being capable of cutting, grooving or sanding an unlimited length of material with the use of side extension clamps. The multi-functional woodworking guide is compact, portable and easy to transport, as it fits into the back seat or trunk of a car. The multi-functional woodworking guide is easy to secure to a work piece by various integrated clamps, which do not have to be move when cutting, grooving or sanding the material.
