[TCML] Secondary self frequency

[Andrew Robinson <teslamad@xxxxxxx>]

Does this sound strange to anyone. A 4" OD x 22" (windings) secondary 
using 22 gauge wire with a 4.5" x 18" spun alum toroid having a self res 
freq of around 515kHz? I ran the tests in the lab today and thats what 
im getting. For some reason though, I had reason to believe it was going 
to be much lower. I'm gonna resubmit this email next Thursday when I get 
a chance to get back in the lab and im gonna take a video of myself 
taking the measurements. Maybe im just doing something wrong. I just 
threw this website (http://www.teslamad.com) together just now for the 
purpose of this email. Please go check out the pics to get a better idea 
of whats going on. This coil isnt finished yet. You may have noticed the 
quickie ghetto gap and, my old rotary disc from an old BIG coil on my 
new RSG mount. In addition to my freq question above, I also have 
another... im not getting anywhere near what I expected to, performance 
wise with this coil. 2 - 6in max off a break out point. By the way, that 
toroid i just got in the mail today from OW landergren... Most amazing 
craftsmanship I have ever seen and extremely robust and heavy duty! Took 
it to the machine shop today to center tap it and it was "over" a 1/4" 
thick of aluminum in the center. Just google them.

I know everyone needs numbers to even begin to help me and I figure I'll 
resubmit a detailed report of my findings to the list like I said, next 
thursday. Hopefully then with plenty of data, pictures, video, etc... 
someone out there will say that catchy phrase "Well theres yer problem!" 
Thanks everyone! Hope you all enjoyed my new coil pics... even if it 
doesnt work hahahaha.

Regards,
Andrew Robinson
