Step 1: Supplies for a Secondary
To build the secondary coil, you will need magnet wire, a form to wind the wire around. The form can be cardboard, PVC, or other non conductive material tube.
Step 2: Good Place to Wind
Winding the secondary is the longest most tedious part of making a tesla coil (IMHO)
So its a good idea to find a nice place to wind for hours on end. I picked a shady spot in the backyard.
Grab a stool to sit on, I also recommend a pair of gloves, magnet wire can be pretty rough on the skin after a while.
Also, have a roll of tape sitting near so you can tape down your progress as you go along, its no fun seeing hours of work unwind!
Step 3: Now the Setup
This is a pretty simple setup if you have these supplies sitting around. I just flipped a bench upside down, and covered the legs with old rags so the form would rotate easily as I wound the wire by rotating the tube.
