After releasing the ends you have a roughly radiused brace. I suppose going up one dimension one could, if strong enough, deform a cube and plane it into a sphere. (That was a math joke. I promise math people are laughing. Somewhere.)
Thanks for posting the pics.
Yeah, at first I was concerned about that too (hence I put screws in circular fashion) but as you can see from the picture partially sanded board looks very "round". You could also use thinner material attached to thicker bottom board and more screws if you're concerned about having "perfect radius". This method certainly beats the sanding-by-hand method but it doesn't say nowhere that you can't "touch it up" by hand, around the perimeter for example.
I do bend the braces and sand them on edge sander, I keep them taller so that when I finish sand them on the radius board they're stiff enough to keep the shape and don't bend as the brace is pressed down. Later they're cut down to right size.
Thanks for comments guys.
