2nd diagram
That looks much better, Mart. Thanks. As can be seen in the 2nd diagram, the capacitor value is 1 picofarad, 20 kilovolt. The spark plug gap is suggested to be 1 to 2 millimeters, which would be .040 to .080 inch. I would start on the low side for the gap, using .025" to .035" which will give you lower voltage spikes, but the spikes will occur more often. See what your results are, then try larger gaps under similar weather conditions to see what the difference is in battery charging rate. It's important to compare under similar weather conditions, because colder days and inclement weather will naturally increase charging activity. Remember too, that whatever your spark plug gap is, the gaps in your overshoot device should be about .010" larger. As I said before, you can make your overshoot safety device form two parallel boards with adjustable bolts to make the gaps. You could also use three more spark plugs instead of the bolts. Here's a diagram of the solid state antenna charging system, with the overshoot protection seen at the left side of the diagram. [IMG]

I haven't seen the SG rotor made from steel though? Is that because regular mild steel is magnetic and would interfeir with the magnetic feild? If so why not use a 300 series stainless steel as it is non-magnetic in annealed form plus it is nice and heavy so it would carry alot of momentum, granted I know stainless steel isn't very cheap.
