Building wooden toys requires sanding small pieces, often in hard-to-reach places. To speed up the process, I bought an inexpensive battery-powered toothbrush from the drugstore and turned it into a miniature detail sander.

To make one, first pluck out the bristles of the toothbrush with pliers. Then use a gasket hole punch (Grizzly G9845, 800-523-4777, the same size as the toothbrush's head to make tiny sanding disks out of adhesive-backed sandpaper. Apply the sandpaper disk to the head and show off your smile as you brush away your project's rough edges.
