Hereare a couple of alternate sources for stainless steel hemispheres obtained by trolling around using the Bulls Eye search engine:
Sharpe Products www.thomasregister.com/olc/sharpeproducts/prod8.htm Stock SS hemispheres to 6", cheap prices, other sizes on request.
AMS Industries www.amsind.com Custom spinning house, large sizes available. I must point out though, that if you opt for a size larger than 10", the price for the necessary flanges will be extremely painful...
Of course, there is also J.G. Braun at www.jgbraun.com, cited in the old BBS and elsewhere.
