Glenn,
You used the same wire that I did with my toroids although I measured mine at
650 and 700 microheneries. We need to wind these with many more turns of
smaller wire - like 16 or 18 gauge. The goal is to get up to 4 to 6 mh. The
voltage rating of the wire should not be a problem since the delta voltage
between adjacent turns is very small. You should wrap the toroid core with
some insulating tape before winding the wire on however.
