Tesla Coil: Secondary Coil





Introduction: Tesla Coil: Secondary Coil

How to get a nice/free winding station set up for a medium to large sized secondary coil.

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.

    Hi,good day.My secondary coil just cutd away from my tesla coil please help me

    if i used 22 guage wire instead of the 24 magnetic wire do i have to redo it?


    No, you just have to make sure your coil tunes

    Good luck, and do some more reading!

    I wish somebody would make an easy to understand, small, and as un-complicated as possible tesla coil. I'm a long exposure photographer and just want BIG sparks. I'm not AMAZING at electronics but i do have alot of know-how, but all the instructions available make no sense. Will somebody just make it simpler.

    if your looking for sparks, try a microwave mots transformer, use the middle prong on the base plate. big sparks.

    one of the best resources for making a tesla coil is http://www.pupman.com/ - they have years of archives of coil building adivce to search through, or you can join their mailing list and ask what questions that you cant find answers to in the existing knowledge base

    Tesla coils are extremely simple. They are just air-cored resonant transformers. Capacitor charges, sparkgap fires, primary coil fires, secondary coil picks up current, bang you have sparks. If you can't get an even basic understanding of tesla coils then maybe it isn't for you..

    I have done a lot of research on trinary coils. They seem cool. I kind of built one, but it wasn't very big. I got 4 foot sparks from 5 amps, though!

    I'd love to see an instructable on it. would you just design the secondary circuit similar to the primary's, except with all tolerances, ratings, and values adjusted accordingly?

    I'm just a curious bystander in this conversation, but has anyone thought to try to set that pvc pipe up on a motor to slowly rotate? Then you let the motor do the work while you simply guide the wire. Seems like it would save a LOT of time, given how much wire you have to spool onto it. Just an observation.
