Re: ATM Advice with Flexing a 16"
Here is a thought on support during grinding.
After the back is shaped, cast a plaster or cement "tool" against it as if
making a lap support. When it is cured, flip it over, line it with something
firm but springy like firm, thin foam rubber and put the mirror on top to work
the upper face. shouldn't be too much different from working a thin mirror on a
cushy pad.
