Then what happens is you end up somewhere down the line with the dreaded "clicking crank syndrome". So grind or file that seam off nicely so you get a good seat for the cups.

It would be easier to point it out on a bike than it is to describe it. The steerer is one of those extra heavy duty ones from Schwinn as well, so it takes a smaller stem diameter.
