Hello David, All,
I know this topic has been beaten to death, but I just had a moment to find old and relevant files. Below is my failed design.
I built an EDM oil (made for high voltage oil) quenched spark gap circa 2002. See links below for pictures and design. I connected a 10,000 volt 60hz transformer across it to test it. The gaps were set too wide at first and I finally narrowed them until it started to spark thru the oil across the gaps. Upon sparking, it immediately created gas bubbles. This could have been vaporized EDM oil or broken down precursors, I really don't know. I think I remember carbon flecks in the oil afterwards too, but not for sure. It was instantly obvious that this was not a viable way to have a consistent, rigorous quench. In less than 10 minutes, I turned it off, never to run again.
