Just wondering, how did you build that beautiful Primary I see here: http://K2.peakpeak-dot-com/~terryf/tesla/misc/manyc009.jpg I would LOVE to make one that looks that nice! What kind of wood is the base from too... I couldn't find much in circles, I could get a large sheet and use the jigsaw though.. ;) My primary just didn't turn out well.. lots of kinks in the pipe.. any hints for a beginner? On the MMC, what are those caps you are using? Travis
