I rescued an optical flat that was being tossed because it was chipped on the edge. I'd like to use it to locate burrs on gage blocks. What do I need as a light source? I have heard that a white ping-pong (table tennis) ball illuminated with a laser pointer might work. Simple, small, inexpensive suggestions welcome!
