Yes, it's Woodturning Workshop, hosted by Tim Yoder. The link is:
http://www.iptv.org/series.cfm/13055/wo ... hop/ep:408
He did 2 episodes on metal spinning, episode numbers 310 and 408. You can purchase copies of the episodes through the website, or wait until they are replayed on your favorite local PBS station.

I have a set of heavy-duty tools for spinning metal that I picked up a few years back but never got around to giving them a try. As I recall from many years ago watching metal spinning, a heavy metal turning lathe was necessary as the metal being spun seemed much thicker than the .040" aluminum being sold by Penn State Industries. The tool post/tool rest was rather stout so that the necessary pressure could be applied to force the metal to conform to the pattern/mold. Also, it was a very noisy process. Some of the tools used were homemade of wood. Another point is that the wooden forms or patterns used to shape the metal need to be quite smooth otherwise any defects in them may be telegraphed to the metal.

Not done this myself. Haven't quite had the need yet. I do think a few mods would be required but for light work the shopsmith should handle it. I think the standard tool post would need a pivot point though.

Great information and thank you for the feedbacks, you guys are great.
I am looking at doing only lightweight spinning, and the Penn State kit looks like an attractive way to get started at least to get me feet wet with entry level work.
I'm looking specifically to work my way up to chalice like objects and bowls. So it wouldn't need to be too "uber" a set up.
