16.2-Inch-Mirror-Blank-Project

I originally started with a 16.2 inch diameter mirror blank with circular web back pattern. This was a mistake due to stress being concentrated in the narrowest part of the webbing. This being said a 16.2 inch disk was worked and a good figure attained in spite of what might be considered a risky anneal.

What does this tell us? Because my anneals have gotten much better and the circular webbing moved away from that our end product is workable. Whether picky anal astro types wince or not is not the issue. The issue is not emotion but rather IF something can be done and with what level of difficulty. The answer is YES it can be done and at reasonable and comparable effort levels for the mirror design at hand.
