I've straightened a couple of forks to good effect but lately I've had a couple of really difficult ones. Turns out one of the blades on each fork (the one with the chrome missing) had been slightly straightened (lost it's rake). I need to re rake these so that the dropout is the same distance from the crown. As the bend get's straightened out it effectively lengthens the blade which makes any other alignment useless. Here's the fork alignment jig that I made. It gets things pretty darn good from side to side and front to back but I need to make a good guage to measure from the dropout to the brake hole as a millimeter off in length means 3mm side to side.
