Love your fantastic Tesla Coil in the living room!!!
I have a (I hope kit) that needs assembly, but I can't find anywhere the
details about it.
When my friend gave it to me, he lost stuff, including a diagram,
possibly a part or two and instructions with a video how to safly assemble
it.
On YouTube.com I have a video of the parts that I do have and I'm looking
for someone to help me.
If you know someone who can help me, please don't hesitate to send them my
way.
I finished building my lab so now is the time to make a project that would
be my largest Tesla Coil.
Here is the video:

Thank you.
Tony
PS: I have lived in Lincoln, NE since 1981, but English is my 7th language,
so in my retired days, I haven't learned everything yet. So pardon my
version of English! ha ha ha
I'm originally from Czech Republic (Czechoslovakia when I lived there), but
my parents were Hungurain..... for some of you who want to know.
