Attaching Race to Fork
So isn't there supposed to be something to keep the race from moving? I had to press the race onto my other forks but this one is new to me.

Three possibilities
1- the steerer in bulge formed and there is a crown seat, but not as a separate piece. This is fairly common on 1-1/8" threadless forks, so try the crown race and see if you get to an area where it needs to be pressed.
2- there is a seat in the form of a pressed on ring, that a prior owner removed with the crown race.
3- the fork was made for a split crown centering cone, of the type used with many cartridge bearing headsets. These don't need a larger diameter seat since they are a slip fit, until the matching conical lower bearing race constricts them.

It's on there snug but I slid it on by hand.

Some crown races are split so they can slide on easily. I would think that as long as it mates properly with the lower headset bearing, you're golden.

To be a bit more precise, these aren't crown races, but crown race centering cones. They're used with sealed or cartridge bearing headsets, where the actual crown race is part of the bearing.

Right, Chris King calls these "Base Plates" , not crown races since they aren't races at all.
