Miniature coil winder
Alphawolf45:
Ohh my goodness I own a commercialy mnufatured ccoil winder that is 1/2 as complex.I have use it for making precision resistors for precision circuits in super precise bridge curcits circa 1950
It aint entirely that I can speel.. I cqant spell. But also this keyboard double tqps on it's own.I get tired of fixing the spelling mistakes.
ddmckee54:
I know what you mean about the keyboards. It seems that there are an awful lot of dyslexic keyboards being manufactured lately. At least that's the way it feels with my last 3 or 4 keyboards. The words that get miss-spelled I'VE known how to spell for YEARS!

Doc:
Well did get my first coil done AND IT WORKS. I tested it on 6v and no problems. I now need to incase it I'm planning on a box a smaller version of a model T coil. Here is a pic I took from the video.
Doc:
Here are some pics of the finished coil. It puts out a nice spark at 6V. The primary resistance is 3.0 ohm and the secondary is at 5600 ohms. I'm happy with the way it turned out one more thing I can cross off my would like to build if I could.
awemawson:
Well done Doc.
(Though I'd be nervous of using plywood as the insulator at that sort of voltage)
