There is an 8 inch set-rite at 495.00 if anyone is interested. I believe this is a set-rite anyway. You would have to find a back for your lathe though. He had a 6 inch, which I got for 425.00. They are both in "as new" condition and include shipping. I thought about bidding on this, but I don't even have another lathe for the 6 yet. These chucks are extremely expensive and this is the first one I have ever seen. By reputation, they are a step above Bison. I think I found a back for 220.00 for my 6. His catalogue numbers don't jive, but by images it appears to be set-rite.
