Topband: Insulator problems- Notr og caution

[Bill Wichers]

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.
