I find that #7 parameters "following the rule of thumb" is... minor dia.of toriod is approximately = to secondary dia. and the major dia is approximately = to secondary length for a good starting point when building a coil.If you want a good performing coil, then you need to design with the following in mind:1) 900 to 1300 turns. 2) H/D ratio between 4 and 5. 3) A coil diameter of 4" or larger. 3) Good static gap with lots of air cooling or srsg. 4) A transformer about 12kV or near with at least 60mA.5) An MMC cap designed for LTR operation (it's value) for the static gap or srsg (and those values are different).6) A primary that tunes between 10 and 15 turns.7) A toroid sized appropriately for breakout, loading size, and as smooth as you can get it.

It of course takes work, time, and money to make a decent coil. It's not rocket science but there are pit falls to watch out for and experience is the best teacher.Take care, Bart_______________________________________________ Tesla mailing list Tesla@xxxxxxxxxxxxxx http://www.pupman.com/mailman/listinfo/tesla
