Hi all,
I researched the archives and couldn't find a definitive answer so I am
going to the list with this question. I am using a sub diameter tool with
this mirror. I'm working exclusively TOT. I know I can control the depth of
the curve with the length of the stroke. I am primarily working COC with
25% overhang. The question: When I do a sharpie test, the lines dissappear
first in the center and then in an evenly expanding circle till the lines
are completely gone over the entire surface by the time I have made about
three trips around the barrel. Logic tells me that this is what I should
expect with a sub diameter tool. Experience tells me that logic might lie.
Can someone verify this for me?
Clear skies, Jerry
