I am making collet blocks for some 3C collets. I turned the blanks yesterday. Just finished the square block. I got it to less than .0003 concentric using just a mill and sand paper. Finished at .995 I was shooting for 1.000 square. That will work for me. Next up is the Hex. Not sure if I will start today or not. All depends on work load. I only can work on down time.
