My '90ish Giordana Spica wanted to veer strongly to the left when riding. I tried the fork alignment that Sheldon had on his site without much success (
https://www.sheldonbrown.com/brandt/align-fork.html ). I decided to build my own jig to try to fix the fork. I built it using parts I had around the shop. I was able to straighten the blades so they were centered and was able to adjust the rake as measured at the dropouts. I used a hub with a mark in the very center and used a straight edge to measure down the center of the steerer to determine how much to adjust. After removing the hub I was able to bend the blades into the proper position. After making the adjustments I was able to ride with my hands off the bars instead of fighting to keep the bike going straight prior to making the adjustments.
