That toroid looks fine. In fact the whole system looks fine. It
looks a bit funny because we wind our primaries backwards from
each other. I start winding from the inside turn out... you start
from the outside turn in. The primary looks smart! You should
have no trouble placing a six inch secondary in this primary and
firing at pole pig power levels...

I see you took my advice and installed a smooth copper plate
ground terminal on a hermetically sealed secondary coil form.
Looks good and my experience is that it will be a super
performer. 

BTW, don't overly worry about the secondary exploding. If the
coil form is sealed tight, there is little chance a spark will
get inside to ignite fumes. After a couple of years the fumes 
will gradually migrate out of the coil form and the explosion
hazard will eventually diminish to zero.
