spun aluminum spheres



I have for sale spun aluminum spheres from 3"dia. to 12"dia.  They are
made in two halves one of which is crimped on the edge in order to fit
into the other half.  hole sizes for mounting can be made according to
buyer needs. They could be used for electrostatic experiments in tesla
coils and Van de Graaff generators.  Please email me for more
information. Ernest Tetirick
