Sanding an Arc

Sanding a curved surface with a square sanding block is like trying to fit a square peg into a round hole. So whenever I have to sand an arc smooth, I use the waste piece from the arc cutout to make a curved sanding block.

To do this, simply cut a small section from the middle of the waste piece (as shown at right). Then apply a piece of self-adhesive sandpaper to the curved edge of the block (see Detail illustration). The curve will match the arc perfectly.
