Re: [TCML] A few questions, any help would be great
I would like to say something here. I don't post much. I leave it to the "experts" most of the time. I agree that there is a vast amount of knowledge in the archives. In fact, one could and should read for weeks at a time in there. There is NO better place then PUPMAN for the Tesla Coiler New or Veterian. The more you know about this hobby the safer you'll be. One could be killed! Now, if all you want to do is sit back and just say that 99% of the info is in the archive and not answer the often over-whelmed new guys specific question, what good is this part of the site. If all of the info is already here, there is nothing left to do! All I am saying is that at all levels, we are here to learn. Some of the people, maybe even me, probably shouldn't mess with this stuff. My knowledge of Tesla coiling is limited. I have built spark gap, VTTC, and a 1/2 bridge solid state coil. I consider myself still new to this. Interest is the limiting factor right now. I have been looking at my 12K 30ma NST for the last couple of weeks. I am thinking of building another. This time, aiming more towards craftmanship rather then spark length. Thanks to everyone for all of their help in the past. By the way, what tank cap will I need for that Franceformer I have and who has the best looking design for a Terry Filter. Thanks...<wink>

All these questions have been asked, and answered in detail, many many times
before on this list.
All the posts to the TCML for the last 16 years are archived on the TCML
website at www.pupman.com. You can easily search these archives for answers
on almost any Tesla coil topic you can imagine (the "Search the Archives"
link is on the left-hand margin of the home page).
If, after searching the archives and reviewing the information therein, you
cannot find the answers to your questions, then feel free to post the
question to the list.
By doing a little research FIRST, you will find the answers to 99% of your
questions, and be able to see the responses, experiences and opinions of a
number of list members.

Subject: [TCML] A few questions, any help would be great
Hi,
I sent these a week or so back and never got any replies, maybe the message
didn't go through. I have done lots of research and recieved much guidance
in building my TC, these items that folow are some of the gaps that I would
like to fill in, to get the best, and safest, performance out of it.
Even if you know an answer to just one of the questions, or can help point
me in the right direction, any help would be appreciated.

How does one calculate a good bleed resistor Ohm and Wattage rating for each
cap in an MMC?
Let's say for example, connected to the 15/30 NST, I have 20 caps, each one
2000 volts and .22 uf, all in series (for 40kv @ .011 uf total)
Is there some kind of equation that I can plug those numbers into, to get
the right value for the bleed resistor between the leads of each cap in the
MMC? Does SG size get involved?
Also, for items that need to be RF grounded to a metal pole in the dirt
-case of a 15/30 NST
-secondary coil
-backflow protection for the NST, gaps to over-arc to a ground point instead
of blowing out an NST leg (I think it's called a Terry filter?)
Should I also ground the strike rail? (also is there an equation for how
wide the gap in the strike rail end points should be, and how high above
/what radius gap should be, between the outermost turn of a flat spiral
primary and the strike rail?)
And can all the above be grounded to the same earth point? Or should
separate ground points be used on .. which items?
