Herb's project is a beauty. I wonder if you could make the box, then use one of the plastic or metal grids that go on flourescent light fixtures. Then have a couple of thin, rectangular masks with rectangular openings to lay over it, leaving openings just a little larger than the item being sanded? You could add a small chamber below the unit to slide in and store the masks out of harm's way. Just thinking.
I really like Stick's idea of, say a 1/4 or 1/3rd inch wire screen below the grid to strengthen it and catch dropped small parts. I'd also use very light weight materials wherever possible so I didn't get a hernia every time I hauled it out for use.
I think I'd put some very smooth material on the slanted boards to keep sawdust from hanging up on tiny rough spots.
The more I do, the less I accomplish.
