I've only made 3 or 4 coils, and even with CNC they are very labor intensive, mainly due to the kapton tape insulation. I'd like to find a thin enamel which I can brush onto each layer to insulate, which would wick into the wire and replace the tape.
One of the coils was mounted into a gas turbine "buzz-box" ignitor. Pressing a button on the box causes a continuous buzzing spark through a 1/4 X 32 plug. This caused instant ignition in my MW54 gas turbine, but the stray votages played hell with ECU electronics, so it was shelved in favor of a conventional glo-plug. |
