    It's interesting to see how far a simple request for accuracy in 
description can lead. At least some useful information on steel 
spheres came out of it. (and a few snotty comments) ;-))

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.

Hi Thomas:

They sell garden ornaments called Gazing Balls, they are made of
stainless steel. They have no recognizable seam and a mirror finish.
They are resonably inexpensive,and come in many sizes (save yourself a
lot of work).

So I don't get flamed by Star-buck intellectuals, they are also called
Spheres.  And yes, I am well aware that when observed travelling at
the speed of light they would look like flat disks. I am also aware
that there are many Non Euclidean descriptions of spheres,
etc...............
