While other people might dissagree, I see little need for them at low
power levels like your's. Be sure to include a properly set saftey gap,
though. (though even that, if things are working well, and there is no
danger of a strike on the primary side, isn't neccesary).

You may be better off using bypass caps and power resistors is you really
want RF protection. They'll be easier to make/use.

Check the "Almighty Terminal" section of my site: www.electrophile.8m-dot-com
for toroid making info. BTW, a "toroid" refers to the donut shape, the
sphere is just a sphere, though both are types of terminals. The most
commonly used material seems to be Al dryer ducting. I, and many others,
use it as-is (i.e. no covering with anything else) with superb results.
For spheres, i would suggest brazing, soldering, or epoxying two
stainless steel mixing bowls together, with first having removed the rim.
And one more question, with
> transformer above, how many salt water capacitors should I use?
Try somewhere between three and six, depending on the size of the caps
being used, and the number of turns in your primary coil
