Tesla coil advancements - Was- Build own capacitors

Original poster: Terry Fritz <vardin@xxxxxxxxxxxxxxxxxxxxxxx>

Hi,
There have been many major "leaps" in Tesla coiling technology recently!! Bill Wysock's big toroids, Medhurst formulas re-discovered by Malcolm, the Corum's suggesting there might be "science" behind TC's, Paul "finding" that science, MandK, E-Tesla, Bart putting it all into "one" universal computer program, MMCs, LTR, Computer models all over the place, finding "exact" capacitances and optimal systems, and now we have the stunning DRSSTCs!!! Many long long stories behind each and many I forgot to mention because there are so many things changing %;-))
I too had to stop and "take a breath" when Malcolm Tesla simply "ordered his Tesla caps from DigiKey"!! For those of use that have oil stains from Tesla caps attempts from 30 years ago "all over everything" (like Chip's house roof ;-))) Simply ordering up the caps from DK for $30 just seems "way way tooooo easy" >:o)))
It is funny how we ran out the World's supply of DK-P10516-ND caps out, then the supply of CD-942C20P15K went dry >:o)))) Now CD-942C20P1K is dry, but I am not sure that one was all "us"??... It was funny calling DigiKey up and ordering a "thousand" caps for "private individual use". They once asked what I was using them for :-))) I don't think they understood the explanation :o)) I just told them I will need another 2000 real soon :o))) I am not sure Rell.com knows why odd private folks keep ordering all those CD caps... Cornell Dubilier "does" understand the "Tesla coil cap thing". We are a big "blip" on their cap manufacturing numbers :o)))
Oil filled poly caps became a "thing of the past" almost overnight.... Many stopped dead in their construction and they tried to sell the unbuilt parts... Some still use them just fine since they have them ready to go! But new construction of oil poly caps is "rare"... Glass and mica cap new construction is best described as "retro" ;-))
Tesla would still recognize the primary and secondary coils (unless you use technology like this http://dkc3.digikey.com/PDF/T053/1618.pdf Part number P6002-ND *8o)))) but everything else is all high tech now ;-))
I used to think we reached about 10% of the coilers directly, I now think it is 20 to 30% based on how fast "non list" folks pick up on things...
With the Internet putting all our minds together, we really have changed "everything"!!!! And, I don't think we are done yet ;-))) 

Cheers,

        Terry

Just a little story: I used to defend all the homemade
caps with a vengance, totally set against the idea the
of spending money.  I had just completed my 14th
homemade capacitor (polyethylene-60 mills thick) and
waited 5 days to drive the air out.  Upon powering the
cap with 15kvAC.  I was delited to see such great
preformance from my first run with the cap.

Only 10 seconds into the run "BANG"... I killed the
cap!  As the oil became darker, my concept of
capacitors melted away and I told myself "There MUST
be something better, something more DEPENDABLE"

I frantically began to search the web for lastng
solutions and I came across something I had never
heard of, It was called an M.M.C.,  I decided to go
and spend a bit of $ and see if this thing called a
Multi Mini Capacitor was really all that great.

Let me tell you that since that fateful day, I have
never even considered building another homemade
capacitor, NEVER!  The cd942 series capacitor is THE
BEST CAPACITOR for tesla coil use, PEROID!
It will OUT PREFORM and OUTLAST *ANY* other
comercially available capacitor for the price.  It is
also MORE COMPACT than even some of the maxwells out
there.

Just a thought...
