So, is the left leg bent back of is the left end bent?

Tools: Var fork jig, dropout/fork end alignment tools, fork/stay straightener, vernier calipers, vice




Assessment:

Fork is placed on flat surface with the shoulders of the crown resting on the surface. Some forks have a more pronounced center section of the crown where the brake bolt goes through thus preventing the crown from lying flat. If your fork is like that place a quarter or 2 under each shoulder.

Pics 2 and 3: Place a stack of pennies under each leg and slide them towads the crown until there's no gap. Notice that in pic 2 the pennies dont go up as far. The left leg is bent back.

Pics 4 and 5 show height of ends from granite counter top. The number is irrelevant because the steerer isnt level, what's importent is the difference in height.

Pics 6 and 7 show fork in jig. Fork is placed in jig, T bar rests on crown squaring up the crown, steereer is then clamped firmly in jig.

Pics 8 and 9 show the end of jig extension. Cross bar on extension slide up and down. I double checked the cetering of the cross bar in pic 9
