If the cutting edges are cut by hand, the cutting edges will not all be the same length and the average radius of the frustum formed by the cutting edges, measured to the middle of the cutting edge, will be different for each flute. That is what I meant by "changing around the circumference". Its hard to explain in words - a sketch pad and a couple of beers would help this discussion come to an early conclusion, I would guess!
