It's hard to align the fork unless you have some accurate measuring tools. I make wood V-blocks to clamp the fork steerer in a vise. Then spin a 2-foot section of broomstick down to 22.2mm and stick it up the steerer from between the blades. Using a T-square, you can measure the fork blades centering relative to the broomstick. Bend as necessary. However, you'll still need to visit a shop and use the dropout alignment-tools to make sure the faces are parallel.
