Our first coil was done off of a 12/30, but the construction was not as 
great as it could have been, so we only got about 15" sparks at best before 
we had to dismantle it. (Sniff...) You could easily get better sparks if 
you take your time and make really neat electrical connections. Also make 
sure you build a coil-winding jig so you can wind your coil and avoid the 
skips that we got.
The best way to improve the coil would be to use an mmc. Although you could 
also say that a more efficient spark gap would be better performance-wise, 
the one reason that I would go with an mmc is that you don't have to deal 
with the saltwater bottles. We did those on our first also and was amazed 
at how much more convient mmc's are when we did our second coil. Hope this 
helps. Good luck!

Hi guys
I am in the process of building my first coil with a 12/30 NST
i've read about jon freu's coil on a 12/30 supply and the 42" arcs he can get

im just wondering if anyone has any idea on the spark/arc size id be able
to get using:

A 2 inch secondary with ~860 turns AWG29

a a static gap of 3-6 copper tubes w/ fan across

primary and torroid are too be made..so any ideas or suggestins
welcome.......?

geek group bucket cap for a LTR cap value (on 50hz) of about 11.9 nf

any ideas or suggestions appreciated

1.what kinda spark out put do you think the above specs would give
2 . how could it be improved (i know this is kinda pre-emptive given i
havent even finished the coil yet....)

thanks
Ruben
