 Looking for the 8-10" hollow metal sphere with about a 2mm wall and roller material.

Thanks for the response

Have you seen the various VdG projects on this site?  Many of them use "scrap" materials you could find most places, and you could go through them, mixing-and-matching ideas to suit the materials you can get hold of.

Off the site, this classic DIY model uses household plumbing, a cheap electric motor, rubber bands and an empty soda can.

+1 I like that soda can design.  Simple is good. 

Another good resource is Bill Beaty's VdG pages:
