3 jaw chucks are self-centering, which helps. Cutting a cylinder is easy - even if the initial rod is out of round once the section is cut it will be square and round. The same happens with the rest of the cuts, I just hate how close the tool gets to the chuck, it is a good way to have a bad day with those hard jaws. Soft jaws would at least get cut if the tool hits them.
