Stop rounded edges with this corner-sanding block
When sanding the edge of a workpiece, it’s easy to accidentally round the edges slightly, but I made a square-edge sanding block that eliminates that. Before assembling the block, I sanded a small chamfer along the inside of the upright. This allows me to tuck the sandpaper strip—cut from a 1"-wide sanding belt—tightly into the corner. I secured the abrasive using double-faced tape.
