I expect spark output using a 1 x 7 inch toroid to be approx 16 - 18
inches long. Not bad for a complete system weighing less than 6
lbs.! I'm having O.W. run a batch of toroids for me. The more
orders the cheaper the toroids will be for everyone.
Anyone that might be interested in a board please advise as I plan on
placing the board order early in November. Contact me off-list and
advise. I will add you to our board bulk purchase list.
Also, contact me off-list and I will email you the pri-sec coil
geometry plans so you can start working on gathering your parts. PVC
tube, wire, phenolic plates, etc.
Happy long sparks!
