It looks like this lapping operation is normally done on a vertical mill with the spindle being dead perpendicular to the table. I don't know if you've seen this site, but here's a guy demonstrating it:

There is also a ton of other info on flywheel alignment on the site.

I have and the problem with it that he indicates the bore of the taper but then does not fixed the wheel to the table. It's allowed to wander and seek it's own true.

If all you want to do is correct misalignment then the wheel can be allowed to float and the technique in the video would work fine. The only reason that it would need to be fixed to the table would be if you needed to change it's position.
