For the price, I'm very happy with chuck. It's a little loose, but I just can't believe the price. I wasn't familiar with a chuck on wood lathe, but this really holds irregular shaped projects. I am trying to make some bowels out of branches. I turn 3" round for base , then turn around and work on bowel side . I was taking too much time to center jaws up on 3" base. So I found some 3/4" round stock, threaded one end and screwed it into chuck.Now when I finish the 3" base, I drill a shallow 3/4" hole in base.flip it over , slip it onto 3/4" stub shaft, then screw jaws up to bowel base. Really speeds it up !
