Corner Edge Drill Jig
Use this with a center punch tool or deep-hole marker to place a mark equidistant from each edge. Holes are placed at 1/8-inch increments, starting at 1/8-inch to 2-inches. The hole diameters are set to match my center punch tool for the given thickness of the material. The tool tip tapers, so the center punch tip’s diameter changes depending on the thickness of the wood. Use offsets to adjust hole diameters, as needed. I used 1/2-inch stock, but 3/4-inch will work fine.
