I like to use the half rounds on the side of mine when making bells and the hollow on the one face when dishing bowl shapes. The large holes are handy for punching and enlarging holes. I have never used the hex nut slots for anything and the cursed thing is so heavy that I can't lift it to turn it over unless there are three men and small boy handy. The small boy is there to put chocks under it so we don't kill ourselves if it slips. I now have it at friends smithy for safe keeping. I don't want anybody tripping over it.
