...interesting conversation. While people are talking about chucks, what are your opinions on Cole jaws for reverse mounting? I am pretty new to turning, and it takes me a long time to make a true jam chuck. Many times I over cut it, and end up using my poorly fitted jam chuck as a friction chuck. I am not a fan of friction chucks because I like to turn the entire bottom. I have been using the "blue tape and hot glue" method, and it seems to work well for me. I've thought about buying another chuck and leaving a set of large Cole jaws on it, but I don't know how well they work. How well do they hold ? Do they self-center well? Thanks as always for your good advice.
