Sounds off topic ;-)  Maybe someone can help you off-list with that.

There are a few problems.

A TC needs a single layer of wire.  Your's probably has multiple layers on
top of eacy other.  The voltage is so high that it will arc from layer to
layer.  With a single layer the voltage can gradually build up to like
300kV along the length of the coil.

A TC needs to be air cored.  However, you could probably remove the iron
easily.

7" is really not tall enough.  It would tend to arc to the primary easily.
A single layer coil naturally gets long to help this.

Cheers,

	Terry
