David,
You may want to try using stones rather than sandpaper. Commonly used for polishing molds and dies, they are available in various shapes, sizes and grits. The good thing is they will conform to the surface you are polishing and won't round off the corners like sandpaper. McMaster Carr sells them as smoothing and polishing stones. They cost $6-$10 each, but if you use them with a lubricant like WD-40 or kerosene and they will just about last for ever.
