If Muzi is right that there are dimensional differences in the steerers, it certainly wasn't enough to prevent my CK headset from fitting and adjusting perfectly.
My threaded Fuji steel steerer is 1.000", my Bianchi threadless is .997" and my Kestrel EMS threaded is .998'. This would suggest there is more variation just in the threaded steerers than between threaded and unthreaded.
For what it's worth, the highly regarded Columbus steerers aren't terribly round, based on my small sample size and talking to a few framebuilders. The ones I get from Nova Cycle are very round - they spec their own tubing. That doesn't mean that Nova steerers make a better/stronger fork than Columbus, but it sure makes it a bit easier to build a fork. I need to use the file a bit for one, hardly at all for the other. Less Vitamin I at the end of the day...
