  • Patent number: 11148216
    Abstract: The Table Saw Depth Gauge comprises a gauge, slide scale, or ruler, that is positioned onto a table saw so that the depth that the saw blade will cut into a piece of wood, or board, can be measured by the gauge, slide scale, or ruler prior to cutting, allowing a user of the table saw to confirm saw blade depth prior to making a final cut. The device also comprises a handheld gauge holder that holds the gauge, slide scale, or ruler into place onto the table saw, securing the gauge into the opening of the table insert/throat plate of the table saw. The gauge may be moved relative to the handheld gauge holder to calculate saw blade depth.

  • Patent number: 10632643
    Abstract: 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.
