Here's one. I had to bite the bullet and spend some $$ to get it. The PSI one that I was using just was insufficient. I thought about making my own, but then saw Carl Jacobson demo this one. I was having to re-chuck this chalice every few minutes with the PSI steady rest. Obviously it just wasn't designed for something this size. No catches yet and I turned for about a half hour on it today. This puppy is beefy and very steady as one would expect. Of course it stays in place quite well, too. I got this from Steve at Absolute Metals via Ebay. Before I got it, I was ready to just forget this project and go on to something else. I'm sure this steady rest will work quite well for vases also. I'm including a couple of pics.
