In general, breakout voltage is determined by the smallest radius of
curvature, 1.5" in this case.  71 kV/inch * 1.5 inches -> 100 kV.  For
toroids, the breakout voltage may be a bit higher.. but for such a small
toroid, it would be unusual if it were greater than 200 kV.

For very smooth spun aluminum, you can probably find a table with measured
corona inception voltages, etc., at somewhere like Ross Engineering, at
least for the toroids that they make.
