I've seen it demo'd one time, on a big OneWay. He really leaned into the tooling, so I expect a mini lathe on it's rubber feet on a workbench would be difficult to accomplish metal spinning. I'd think this is one where you want a solid foundation and some extra weight added to your bench would benefit you. I'm not sure what kind of HP you need either, but probably another case where more is better. Although, I'm sure PSI's kit would be suited for smaller spinnings to be done on mini/midi lathe setups. I have not looked at PSI's setup to know otherwise.
It's definitely a practice thing to spin the metal to learn how the metal moves and rolls, and how to avoid the see-through thin spots. You will also need to think about your forms when you start making items that close over on themselves, like a vase -- you need to think how to get the form out, and build your form like a jigsaw puzzle to do it. Building the forms looks like it would be a craft in itself. Your tools need to be well maintained, keeping the mirror polish blemish free on each of the "spoons" or "burnishers".
That said, he made some great looking pieces - some were stand alone metal items, and others were used to compliment other wood turnings.
If you decide to take the plunge, it sure will be nice to see photos of your progress.
