Re: Aluminum Sphere for sale

For what it's worth, I paid $14 each for 12-inch-diameter stainless 
bowls from Ikea that I plan to weld into a sphere... um, sorry, to be 
absolutely accurate, it'd be an oblate sphereoid with 3" diameter 
flattened poles, for you mathematical ANALysts... so, about $30 with 
tax for a foot-(major)diameter sphere(oid).

If I'd seen the auction sooner, I would have bought it, sanded down 
the rim, welded it back together, and sanded and polished it again to 
make it smooth, as I plan to do with the bowls. Seems a good deal for 
the price, if you're willing to put in a little elbow grease and have 
a TIG welder and belt sander laying around.

Oh come on! Sure, the definition was generalized but there was also a
picture to go along with it. It isn't a big deal. Semantics? Are you
kidding me? Please, let's get back to coiling! Woo Hoo!!!

Take care,
