Take the pain out of scrapes
Bending a card scraper and holding its shape when using it can be hard on your hands. End the pain with this simple jig. To make one, cut a concave arc—I made mine 1⁄2 " deep at the curve's apex—in a wood block. Then, drill a hole through its center and the center of the card scraper. Finally, fasten the scraper to the block with a machine screw, washer, and wing nut.
