Headset replacement continued.
Put the old headset nut on the fork. Wrap the fork in protective covering. Put it in the vise with the blades vertical of each other. TIghten the vise tight enough to act as a ledge for the crown race. Do not tighten enough to engage the fork blades. Hold a 2x4 section on the headset nut. Strike the 2x4 section with hammer until the crown race comes off.
