Re: discharge sphere?

Original poster: "Dave" <dgoodfellow@xxxxxxxxxxxxxx>

Since Waterscapes gazing balls went down, I have found the best overall price/service on the gazing balls to be from, believe it or not, Amazon.com Prices are a bit higher than what I paid from Waterscapes, but the service is far better. Waterscapes lost my order twice. There is of coarse the occasional lucky ebay find. I purchased 2 12" stainless gazing balls from a seller on ebay, brand new and flawless for 20.00 each, and actual cost shipping.

Sorry, he IS showing an 8" one with stand - his main description was just poor.

There's a gentleman on Ebay that sells them in various sizes pre-done with insulated handles or stands and long ground cable for relatively cheap. I've bought a few from him and they're good quality, but they are quite easy to dent.

Here's one: <http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=7614867472>http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=7614867472

He isn't currently showing any of his larger ones - I've bought some 6" and 8" units from him, both handheld and with tripods.

Sure!  Those stainless steel gazing balls are fine.

The metal is roughly 1/16 inch thick so they are pretty light.  The
steel is very hard so they don't dent easily.  Not as perfectly
shaped electrostatically as a toroid, but they are cheap and easy
"nice" terminals.  They are pretty scratch resistance and can be
wiped clean easily.  The surface is mirror polished with small
distortions and where the two halves were welded but they polish all
that out in a final step so you don't notice.
I used to get them here:

But the link is dead now.  But they are common if you search
around.  Be careful of the price since the fancy home center stores
have a high markup on them.
