On a related note, I just came across a 5", 5C collet chuck at a website called Little Machine Shop. I can't post any links to it, yet, since I'm still new here and need 5 posts before I can. Has anyone had any experience fitting this collet chuck to their Atlas lathe? How much work is involved? Is the quality good? It's about $225+, which is a lot more reasonable than a Bison or something like that.
