Not much to say about the strike ring. It was constructed from 1/4 inch copper water pipe with 4 elbow joints that were sweated together. It was directly grounded to the bottom of the secondary coil. Mounted it to the base using wood blocks to elevate it above the primary coil.

The wood blocks had a piece of PVC pipe glued to the top that the strike ring could snap into. The photo below shows the sweated strike ring.
