Jim, Nice write up and explanation. I read previously that not using a breakout point of a nail tip, needle, pin (how is the pin attached - from the inside of the toroid where the flat round end is touching the toroid and pin breaks through the outside of the toroid to emit sparks?) will cause a 40% reduction in spark length (vs having a breakout point) by having multiple sparks randomly around the toroid.
I stick the thumbtack on with tape: shove the pin through the tape's sticky side and then stick it on the toroid.
It sounds to me that having a breakout point is the way to go for having the longest spark length then. I will still build a bigger toroid with 8" aluminum ducting but if you don't need the $20 a roll aluminum tape then a breakout point should be the answer then.
