Brian -

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.

Regards,
Herr Zapp

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?
