If you try to use a palm sander to sand a small piece, the motion of the random orbital sander can cause the piece to spin away. This jig holds it in place.
To begin making the jig, trace the puzzle shape on a piece of Masonite.
Cut around the traced line using a rotary tool. Use a 360-degree bit so you can cut in any direction. Cut slightly wide of the line. You may choose to make a clearance hole.
