I just traded frames and got an 80s Raleigh frameset that I'm gonna convert to a fixed gear. The fork crown race is actually loose, so that it spins around the fork crown more or less freely. On removing it, I can see that there are some small grooves worn into the crown race seat. Also, the crown race seat is painted, which surprises me.
Is there any way to re-secure the crown race? I was thinking JB Weld, but that could be a bad idea. If I buy a new headset, will I be able to fit the new race tightly onto the steerer?
