Making the Secondary Mirror

Sometimes the strokes used didn't work as expected, so Eric Lee and myself would go backwards from our target. The NC equipment only allowed a thousandth of an inch accuracy +/-, and we wanted to be at least quarter wave and ten micron. So we had to use the polishing equipment and treat it as if it was an optical surface. The cracking problem was the big problem we faced, but we weren't allowed to "kanegen coat" (nickle). We found that aluminum work hardens fast, and gets cracks easy.
