Make this simple jig for turning full sheets of sandpaper into smaller sheets to fit your finishing sander, sanding block or other device.
Cut the 1/8-in. deep grooves in the base using a table saw and thin-kerf blade, then attach the stop block. To use the jig, place the sandpaper grit-side down and run a sharp utility knife down the appropriate groove.
