Using grommets to create additional leakage/creepage distance is clever! I never would have thought of that!
Best is to turn the material on a lathe, but in a pinch you can use a bolt as a mandrel in a drill press and do it that way. Not as nice, but lots more people have drill presses than lathes. -Bill > That problem can be cured with rubber ribs, or by using a larger insulator and > turning ribs or skirts in it.
