Good points. For that matter, the round portion of the ID is equally non-critical to be round or centered, as far as i can surmise. The key is that the clamping screw and V-saddle align to allow proper clamping.It strikes me that the V that serves to hold the round work can be most any angle, shape, even not parallel to the outside faces and off center and not matter an nickels worth. It is the outside surfaces of the block that are the rotational references. The work just needs to be held tightly to the block. Your mill vice provides the constant axial reference for the work. In order to maintain the outside diameter of the work as a reference, I.E. the multi sided work concentric to the round, your mill vice has to be gripping the round. This entire exercise is just another example of maintaining a constant reference.
The reason this fact is valuable to me is that I do not have a rotary table to cut the partial circle. I may cut a square, hex, etc.
It also strikes me that one could mill the several 60 and 90 degree angles with good accuracy using angle blocks against a static reference. For many, perhaps the bottom of their kurt vise. I may need to take a slightly different approach but same concept.
I will add this to the list and probably make it from aluminum. It seems the most force the tool should see is the axial load on the clamping screw threads.
