Sorry for the confusion. I'm talking about a 1930/40s clip-style headset, widely used on road bikes in the UK back then. But replaced by the threaded headset after the war. For those not familiar, the races are built into the head tube. The ball bearings sit in floating races that, in turn, sit in the head tube races. The whole thing held in place by the head clip and a lock nut. A fair number have survived on vintage bikes. But there's not much documentation I can find about adjusting them. I think Mark Petry, above, has it right. In the end, its like any other headset, you have to get the bearings adjusted correctly and lock everything down. I was hoping some of the
older more experienced members here might have come across this.
