looks like an easy one
these steerer deformations just above the crown are quite common
with the fork out of the bike i take a half round file to the interior of the lower end of the steerer to deburr it
then i have a long mandrel just the right diameter to go up inside
with the steerer clamped in the vise using wooden blocks made for the purpose i use the mandrel to do the cold setting
check everything with a straight edge
when steerer looks good put fork in alignment gauge to double check everything and make sure no other cold setting is needed
then back in the bike and robert is thine uncle
whole thing takes no more than three or four minutes
