I use a straight edge and calipers to measure the movement. If you go too far, repeat the process but squeeze the stays. When your done just align the DO's and you're finished.
One note of caution, I always clamp the brake bridge to take stress of the joint.
Even simpler! So you just use a long straight edge on the head and seat tube back to the dropout, and measure the gap, repeat on the other side, and iterate the process until you get the spread and the gaps match? Must be longer than a yardstick, right?
