Excellent little coil. Good workmanship. Nice sparks too. Thanks for sharing the photos.
You've built a very neat, sturdy-looking pedestal for your coil. Any plans to package your components on the bottom shelf? I doubt the salt water capacitor will fit under there, but an MMC with similar rating (9-10nF I'm guessing?) would fit easy enough. Any plans along those lines?
14kv at 90mA NST? What an odd size. Where did you find it?
