Then pass through it one of those carbide covered wire saw , garotte type
things, or even a coping saw blade, kept under tension. Would some scratch
damage matter? If so then perhaps spaced , glued-on, guard rings along the
blade
That's sort of what I've been doing, and have been contemplating making
a tool that is more matched to the job than the strips of aluminum and
other random items I've been using.
I'm coming to believe that any chemical approach will take to long, not
to mention the mess and health issues.
