Re: [TCML] Begining Tesla Coil Project

You never really need a Terry filter, it is just insurance, I've never 
used one.  Just be ready to pay the price if something dies (which is 
not too unbearable if your caps and transformers are cheap.)  I'd 
recommend downloading TeslaMap for sizing your stuff up correctly, it is 
free and is a small download (hmm, it seems it isn't free anymore) and 
is easier to understand than JAVATC which is much more thorough but 
intimidating to a complete newbie.  But rule of thumbs,
1000-1500 turns secondary
4.5/1 height to diameter ratio (so for 3-in diameter you want 13.5 
inches of windings)
use multi segment gaps with a little airflow, or a single gap with much 
more airflow,
gap width doesn't exceed the distance the xformer can ignite an arc by 
more than a tiny tiny bit.
if you use homemade caps insulate them.
If you want a more detailed document I can send you one and give 
recommendations for a 6/60 NST, just shoot me an e-mail
