Issue with a frame.
When the forks are fitted and you turn them, the motion is not smooth and is staggered /jumpy as if there is an obstruction in the head tube or an issue with the H/S or H/S bearings.
Taking apart the H/S to investigate, I find that the crown race and bottom Cup have indents pretty much all the way around from the H/S bearings -
