Original poster: "Scott Bogard" <teslas-intern@xxxxxxxxxxx> Adam,The .75in. total spacing I use, is to make my primary tap easier to move around (I am using some random clip thing I found, I don't know what it is for, but it is a copper/aluminum alloy, and it is too wide for 1/4 in spacing). I am out of tubing, could I use a couple strands of 12 AWG house wire? I have tons of that, and I could insulate it in some PE tubing (that costs 15 cents a foot!) I have used a similar method for the inter-power supply connections, and have not been shocked. I have a shop vac, that "died" but still runs, so I could construct a SG similar to the one you showed me, I don't know if "power arcing" is a problem for me as I have not actually looked (it wouldn't suprise me though), and I cannot check until it stops raining here. If the new blower does not help, I will build a sucker gap, and see how things go. Thanks
Scott

It's fine to use smaller conductors from your transformer to the tank, but once your spark gap conducts, you want really big conductors involved. Consider using 1/4" tubing if you have any left. Forget about insulation; just run your conductors with lotsa space. Your primary has .75" spacing between turns? Is that center to center, or clear space? In any event, unless you're using higher than usual voltage, most folks use the tubing diameter for the clear space, or twice the diameter for the center to center diminsion. As to your gap, bolts filed to a point are not the best configuration. Consider a sucker gap like this: http://www.hot-streamer.com/adam/shopvac_gap.jpg I've run it with a fair amount of pig power before. It took over 20 kVA to melt it. Good luck Adam
