I needed a buzz coil for a little Stove Pipe Domestic I just got from a friend (the Herder engine casting set, with about 4" flywheels). One of the things I always loved about my good friend George Luhr's models what how he hid the coils in a relatively small base and used 2 AA batteries for ignition so you could walk around with his tiny models.
Well, I wanted to hide the ignition in the small coil box on this engine, so I was looking at how others used the standard auto relay's and a regular coil for a buzz coil. The complaint occasionally is that the 12v relay needs 12v for the ignition. Enter George's use of the Modelectric 3v model aircraft coils. I thought why not get a cheap 3v coil relay and try the same setup. Well, I must say so far it looks great! I need to hook it up to the engine and test longevity, but it seems to throw a wonderful healthy spark!

Looks like a fine spark from here!
If that doesn't light the cylinders "candle", I'm not too sure what would!?!?
Very well done, Jared..!!
Yet another reason to be thankful for having George in your life.
I just know he is still with you and smiling!
