There are three measurements that matter. 1. If the two blades are off to one side, that's the easiest to fix, and I have done it successfully.

2. The rakes must be the same. This is the distance forward of the plane formed by the steerer tube. This is harder to get right.

3. The length of the blades must be the same. Sometimes when correcting the rake of one blade (2), you alter the length. This is why I've found fork alignment to be so tricky. When you fix (2) or (3), you worsen the other.
