Terry,

Yes, the place is only maybe 1/2 mile from here.  I agree, the s s material
is thick.  You really have me thinking of building a Van de Graff now.  I have
a small sewing machine motor that I could use.  Have you cut the hole in your
gazing ball yet?  What design criteria have you got figured out so far?  What
diameter form (pvc?) and how long from the base to the bottom of the sphere?
