Tool Tip #14: New Grit for Sanding Sponges

The aluminum oxide abrasive used on sanding sponges typically wears off quite fast, but those sponges make excellent blocks for other sandpaper.  In fact, the grit provides a flaccid velcro to hold sheet sandpaper (same width as your block sander) or a used disc from an orbital sander.  You'd be surprised how effective even a used disc can be for contour sanding.  Note also the crutch tip on the vise's release lever...to prevent power cords drawn across the vise from pinching and getting stuck.  Am I the only woodworker to whom that's happened?
