The Primary Coil

The Primary Coil is one of the two parts that makes up the primary circuit. This is the high voltage exposed coil so DO NOT touch it when the coil is on. Now you can use a normal wire for the primary but it is better if it is a copper tube. This part is harder than it looks as getting and securing the tube in place without it moving is not easy. I did it by cutting holes in pipes and sticking the pipes with supper glue onto the coil base I made in the first step. You can just drill holes in the wood as it would be easier but I did not have a drill at hand so I used my solder to burn through the plastic pipes.

Now just thread the primary coil tube through the holes to make the pancake shape we need. Don't forget to use the measurments in the CAD program when making the primary. If you are making one with the same ratings as mine you will need 5 meters of this

Tapped between turns 6-7.

AS this wire is not very malleable you will need to put the pipes on the coil of wire BEFORE you glue it to the wooden base. It takes a long time but it can be done with some patience.
