Are you sure the steerer is where it's binding? Sheldon talks about the headset locknut being the limiting factor, which would require different work to make it fit.
I'd loosen the locknut and see if those 2 non-fitting stems are being held up there before sanding down the stem.

It's for sure not stuck on the headset. I had the fork removed and the other stems wont fit. I filed the inside of the steerer a bit to see if that helped, but it wasn't close to enough.
I'll take some emery cloth then sandpaper to the stem and call it a day.
