Actually, that is not what I meant. To keep the wires from sparking between themselves (thru the insulation), the wires need to never get any closer together than the spark gap. If you have a 1/8" spark gap in the spudgun the wires should never get any closer than that to each other. Generic wire insulation is usually only rated to 300V or so, at 100KV the insulation is not very effective. If you hold onto the insulated wires and fire the stungun you will get a shock, though not nearly as bad as if you touched the stunguns gap.Surlyman wrote:Good info to keep the spark gap the same as the stu gun.

The actual gap in the spudgun should be a lot less than the gap on stungun. My "100KV" stungun has a 3/4" gap. It won't actually spark that gap, which means it isn't putting out anywhere near 100KV, probably closer to 20KV. (I suspect the spark is jumping between things inside the gun.)
The gap in the gun should be smaller than the main gap and secondary gap (backup gap, safety gap?) of the stun gun. You want the spark jumping your spudgun gap, not the gaps on the stungun, or somewhere inside the stungun.
Another reason to keep the spark gap small, compared to the stungun's gap, is that it'll keep sparking even as the stungun's battery goes dead.
