[TheForge] metal spinning

[Ben Barrett]

I also found http://en.wikipedia.org/wiki/Metal_spinning to be
informative... there are some links on that page you might enjoy:
external resources like a little movie, other websites of reference,
etc.

If you order online & are patient enough for book-rate shipping, they'll ship for free on a $50+ order.  Sorry for the plug but they've been a terrific source for my workshop library!
