Well, My main focus is to make a seconday single winding able to produce about 20KV + and a little more AMPS then a standard ignition coil, so I'm going to use 36 gauge since I have some already. The standard ignition coil I took apart uses much thiner wire.
A bifilar secondary would require some special wire with supper heavy duty coating, so I'm sticking with single winding for that.
Now the bifliar chokes will be done with 24 gauge wire heavy coated.. still don't have it. trying to find some.
if you guys know a good place to get it let me know.
The primary will be done with 20 gauge wire standard coated.
I'll be posting updates.
