RE: [TCML] Bombarder transformer grounding

I believe Tony of Specialfx Neon has built a nice coil which is powered
by a bombarder. 
I see him on here once in a while. 
I'll send him an email and tell him his expertise is needed.

Subject: [TCML] Bombarder transformer grounding

I have a Voltarc/Hyde (Willick Engineering) 30KV 250ma 7.5KVA bombarder
transformer that I am planning on using for a teslacoil.
It comes with a big slide choke.

>From talking with an engineer at the company, it sounds like neither 
>the
primary or the secondary are grounded to the core at all. The thing
looks like 2 big coils wound over the primary. The core is just a big
rectangle with the primary and secondary on the same side. I am guessing
that the secondary winding starts from the outside of one coil, goes
down to the middle, near the primary, hops over to the inner side of the
other coil, and then would back out.

I am wondering how I would hook up the grounds on a Terry filter and
other parts of the system. It is not the same as a neon transformer
where the windings are connected to ground on one end. Right? Do I use
just one leg of a Terry filter?
Which ground would I hook the core of this thing to?

I would like a clear picture of how the whole thing should be hooked up
and how the grounds should be hooked up to things here.

I know it is not in oil like a pig. But with a big terry filter should
it hold up better than a neon transformer? Then again, it is not potted.
It sure looks beefey. Overall it is 19 x 15 x 10 and weighs an awefull
lot. Not counting the terminals. What is the concensus here, should I
use this for a coil?
I thought I remember someone here on the list using one of these on a
coil once.

It looks kinda like this:
