A jump cutting device for use in forming a wooden work piece includes a cutting tool, and a mechanism for moving the cutting tool at an angle between the direction of a crosscut and a direction perpendicular to the cross cut direction. The deepest portion of the cut into the workpiece occurs on a tangent point of the tool. The profile of the cutting tool is a blend of the lineal and cross grain profiles.

A bearingless groove router bit includes at least one cutting element affixed to a head of the router bit and has a first end spaced from an end of connected shank connected to the head and a second end adjacent to the second end of the head. The cutting element includes a cutting edge extending along the cutting element between the first end to the second end of the cutting element. The cutting edge may include a radial side edge that projects radially inwardly relative to a central axis of the router bit and a straight side edge that extends from an end of the radial side edge outwardly relative to the central axis to minimize tear out during cutting of a groove in a work piece.

A method and device for inserting a tongue in an insertion groove in a panel. The method includes displacing a first tongue to an end position of a tongue queue, which comprises tongues under compression, in a tongue queue device, compressing the first tongue, displacing the tongues in the tongue queue by compression forces from the tongues under compression, displacing a second tongue, which is at a front position of the tongue queue, to an inserting device, displacing the second tongue into an insertion groove in a panel by said inserting device.

The Handheld Dovetail Joint Template and Saw Guide is a handheld jig device utilized to mark and/or cut pin and tail cuts forming a dovetail joint. The jig device includes a base with two angled, planar surfaces-a pin surface and a tail surface-opposite each other. A user holds the pin surface along the top edge of the pin board and marks and/or cuts the lengths of the pin portion of the dovetail joint. Next, the user places the tail surface of the base along the top edge of the tail board, aligns a retractable arm against the length of a pin cut, and marks the tail board along the angled, planar surface of the tail surface. Once all pin and tail cuts are formed in this manner, the pin and tail boards are fitted together.

A handheld mortise forming device includes a base unit having a first support extending parallel to a first axis. The first support includes first and second working ends. A first sidewall and a second sidewall are connected to the first support. One of two connecting units is rotatably mounted to the first sidewall. The other connecting unit is rotatably mounted to the second sidewall. A second support extends parallel to the first axis and is connected to the two connecting units. The second support is rotatable relative to the first and second sidewalls and includes an abutting face. A clamping unit includes a pressing member located on a side of the second support adjacent to the abutting face. The pressing member can clamp lumber. The pressing member is jointly rotatable with the second support and is switchable between the first working end and the second working end.
