Hi Bent,
No they get further refinement. I think about 8 steps in all. After sawing them off a fixture was needed to do the surfaces on each side of the rocker. I already have an assortment of small clamps that I have made along the way. The fixture has a center post which locates the rocker then the two small clamps hold it in place. .015 is taken off the center boss and another .015 for the area around the boss which defines the circular shape and the bosses on each end.
