Headset replacement continued.
Mount the fork on a 2×4 section sitting on something the has the fork dangling as pictured. The boxes are for reference only. I actually used stacks of bricks. Remove the old headset nut. Slip on the new fork crown race. Turn the old fork crown race upside down and slip on above the fork crown race. Slip on section of PVC pipe. Hold section of 2x4 to PVC pipe. Strike 2x4 with hammer until crown race is fully installed. Remove old crown race and PVC pipe.
