Build Your Own "Cordless" Detail Sander
For small or occasional tight-spot sanding chores, try building this hand-powered corner/detail sander. Cut the handle from a scrap piece of 3⁄4 " hardwood plywood to the shape shown. Make the grip end long enough to fit comfortably in your hand and round its edges.
Now, make the triangular pad with 21⁄2 " sides, each cut at a 60° angle. Attach the pad where shown, apply a piece of self-adhesive sandpaper to the bottom of the pad, and sand away.
