I use a 4 jaw chuck to hold pistons in my Bridgeport all the time. I f I need to mill any off of the top I clamp the chuck to the table and if I need to gas port them I put the 4 jaw in the super spacer so I can gas port above the top ring land from the side.
All of my 4 jaws are independent but I have seen one that was a scroll type.
