Tesla Coil.

It sits there spitting, like a fugitive from a mad scientist's laboratory. The current it's discharging - in a wicked, noisy 2 inch brush - is of such a high frequency you can't measure it, but maybe it runs up to 40,000 volts. Feeling just a bit suicidal, you move a coin toward this geyser of fire. The greedy tentacles snatch toward it, but there's no shock.
Even if you poked a finger into the brush, the current would just splash over your skin.

Five pages ( 3 sheets - front and back on first two sheets, front only on third sheet ) B & W photos, illustrations, expanded view, parts list and instructional narrative.

My plans are from original source materials such as books, magazines and other publications and the pages are carefully removed.
