Wiring the entire circuit

Hello Again. Thanks to everyone for their responses to the post I made a 
two weeks ago on 'Advice on Primary'. This is for my senior design project 
which is due by MAY but our goal is to start testing ASAP and then modify 
our design to enhance the performance of our TC. We are at the point of 
connecting the entire circuit but before I go into that I want to tell you 
about our primary.

I decided to go with notches instead of holes. It took about 7 minutes to 
wind the copper tubing through notches. I had my partner holding the roll 
of copper tubing and I was snapping it on each notch.

We first mounted the 4 supports to the plywood and then started snapping 
the copper tubing (inwards to outwards) as my partner gradually moved the 
roll of copper tubing (in a CW direction). It's hard to describe in words. 
BUT, honestly, it was VERY EASY. I thought it would be a nightmare. I will 
show you the images later on. We got 13 turns so we will splice another 
roll of copper tubing to this end to get a total of 15 turns.

We are using a 15 kV / 30 mA NST and a RSPG (using a 1/6 hp asynchronous 
motor with a variac) similar to the setup shown below:

For the NST I am using what type of wire/strap/clamp is recommend:

1. From the secondary side of the NST to the Capacitor?
2. From the secondary side of the NST to the spark gap? (This connection 
goes to the stationary electrodes?)
3. From the Capacitor to one end of the primary coil? (Is it connected to 
the tap turn?)
4. From the spark gap to the other end of the primary coil? (Is it 
connected to the inner turn?) And from where in the Spark Gap does the 
connection have to be?
5. How is the toroid connected to the top of secondary? Materials used for 
this?
6. RF Ground ­ base of secondary connected with the ground of the NST and 
the strike ring? The primary is not connected to the secondary since the 
transfer of energy occurs as a result of coupling, correct?
7. The strike ring shouldn?t have both ends connected (soldered) correct? 
Are there any rules as to the spacing between both ends?

Sorry for the lengthy email. But thanks for your time and 
suggestions/assistance.
