When trying to deepen the curve on a 20" piece of glass with a
15" tile tool where would you say is the best place to set the tool, I
currently have it set with a 3/4" overhang and thing are progressing
in the right direction albeit slowly,would it be better to move it in to zero
overhang or am I looking at this all wrong?
Just so you know I am trying to get to an F 4.5 from F 5 and have
moved the RoC. by almost 10" already, just hate to continue only to find
it would not go deep enough where it currently sits and really do not want
to waste grit.
words of wisdom would be appreciated.
