Mini Spark Gap Tesla Coil

Step 6 Toroid

I thought about buying a toroid to put on the top of it but im not going to pay 1 to 2 hundred dollars for one so I made my own! So your going to take the 1 Ft 2.5 inch drain pipe and curl it in on itself so it should be in a circle. Stretching it out a little bit will help it some. Measure the inside diameter of the circle and cut a piece of wood or cardboard and place it in the center of the tube. It will look like a space ship when your done! Take the Aluminum plated tape and start taping from the bottom of the cardboard, around the tube, to the top of the cardboard (it is extremely sticky!). Get the tape as smooth as possible! Its easier said than done but get is as best as you can! Once you got it covered with aluminum tape, Drill a hole in the center, put your nylon bolt threw the hole, place the washer and nut on the other side. Be sure to scrape the enamel off the wire to make a good connection with the toroid!

I was just wondering if metallic spray paint would be conductive enough for this purpose? A can wouldn't cost much more than a roll of aluminum tape. It would be easier to keep it smooth.

Not really for sure, I can get some and try it but I dont know how much metal is in the paint.
