Eccentric turning chucks

The only experience I have with them is watching, but I own one of the Ruth Niles set ups which is mostly for smaller pieces. Carl Jacobs sells them now. You can do a lot with them, but I think they are more for smaller flat pieces, like 1/4 inch thick or so.

What sort of work do you want to do with one?
Absolutely the correct basic question! Followed, perhaps, by "why".

Most -- if not all -- multiaxis / eccentric work can be done without the expense of a commercial chuck. I do a wide variety of multiaxis turning without a special chuck. At club show-and-tell sessions, people often ask "what eccentric chuck did you use?" which assumes that one is essential. Or "what vacuum chuck setup?" I have yet to find the need for any. For example, for spindle work see Barbara Dill's work (and her book). The Duxchuck, and many variations, provide a nearly no-cost alternative for smaller things. For perhaps the ultimate , look at Derek Weidman's work -- he does everything between centers. I've taken two of his classes. I don't do animal sculpture, but I learned how much can be done with very simple equipment and setups. My greatest expenses have been a safety drive and a couple steb centers. Anything further that I need I can make from scrap material. You can make aids to do what you want, rather than adapting what you want to do to the demands of the equipment.
 
Wow, talk about dangerous...... smashed fingers, ouch.

Interesting idea, how about using an offset boring head in the tailstock to do the cuts keeping your fingers away?

I agree with this. There is so much you can do between centers if you can work out the geometry. I took a class with JF Escoulen a few weeks back and did several variations of multi-axis just between centers before we switched to the No.1 chuck.

The biggest question, as you said, is what do you want to achieve? Multiple parallel axes? Axes rotated around a point? There's a chuck for each effect.
